Failed to play test tone

Question

When ever I try to play any sound, nothing happens.  When I go into the control panel and double click on the “sound” icon, it shows my speakers.  And when click on my sound device or speakers, and hit test, the message I get it "failed to play test tone".
 
Now for some background. 
1. I had a different soundcard that was doing the same thing, but I thought maybe it just "went bad", so I bought a new one.  I’ve installed it with no problem.
2. Yes, all the drivers are up to date.  I've run Windows update numerous times and I've double checked the driver version against the one on the manufactures website - they are the same.  Everything is up to date.
3. The device manager can see my speakers/sound card and it says its working.
4. I started out on another forum "Media foundation development - Re:Vista/No Sound/Failed to play test tone" and read the whole thread, did everything it told me to, and I even e-mail Microsoft to get a hotfix.  I installed the hotfix, to no avail.  Nothing has changed, my sound still does not work.
5. The posters/answers at the above thread said they weren't really audio experts and were directing everyone to this thread.

Please help.

Answer 1

I have had the exact same experience up to and including the purchase of a new sound card and absolutely no sound whatsoever.  This is a huge problem for me as my PC does some sound editing as well as provide access to classes on that net that require sound.  I'm completely frustrated.  I have done the same things Chris did above except go for the hotfix from Microsoft but I have scoured the net for sites liket his with any clue.  Sounds like a lot of us are having this problem. 

 

Truth is, my sound was working just fine for months... not a glitch, none of the lag that so many other users seem to be getting.  It worked just great.  Now, nothing....

 

I'm using an onboard ENVY 24 Family Audio with March 2007 drivers which I am told is the latest.....

 

Thanks!

Answer 2

Hi there

Your not alone with this  ... I have the same problem with Vista Ultimate and Motherboard P4M890T-M.

I've searched many hours for a solotion but there seemes not to be one right now ?... I've reinstalled Vista two times already but the sound disapperas when receiving a Microsoft update called CAPICOM ?. I don't now if there is a hardware problem with this motherboard & Vista because others have no problem after the updates .

 

The only way to get the sound back is to load a restore point before the uppdate ?!??!

Please help if you have any clue 

Thanks

Dan

 

 

 

Answer 3

The solution that worked for me without a restore, I didn't have any, or re-installing Vista is to restart the service called "Windows Audio". Just go to start>all programs>administrative tools>services and navigate to "windows audio. Then right click that and click restart. This is only temporary though.

Answer 4

i did the exact same thing, bought a brand new sound card for no reason.

found this solution in another forum, thanks garyd11:

I had the exact same problem and here is the fix.  You're not going to believe it!   1 Go to control panel 2. Double-Click on the Sound Icon 3. Single-click the Speakers to highlight them 4.

Answer 5

Thank you so much, this has been driving me up the wall. good luck to those who didn't have luck with this solution.

Answer 6

This solution did not work for me. I have noticed that my sound works at the Log in screen. It is when I sign in that somehow my sound is stopped and won't come back on. Same for all log ons... Any ideas would be appreciated.

Answer 7

Thanks for posting this solution...it helped me too!

 

 

Answer 8

I want to let everyone know that I found my problem. I had Vipre Beta 7 installed. This antivirus program blocked the sound. The developers are working on the solution. If the program is shut down (or uninstalled), the sound returns.

Answer 9

 

I was watching videos on youtube, and as I went to play another video, the sound just stopped working. I tried to play a test sound, and the error message "Failed to play test tone" popped up. I've tried everything! I have an hp tx1000z laptop with Realtek audio manager.

Answer 10

Thank you SO much! I did this and now have sound again. I can't believe it was such an easy fix !

Answer 11

Aargh, this cannot be! I was so hopeful after I read this and you know what, I don't see the speakers!!! I only have an icon for the soundcard itself, but it does not have the Enhancement Tab. Shouldn't everyone have the speakers??

 

 

Answer 12

I have a HP a1410n desktop, just upgraded to Windows 7.  Fought the Realtek drivers (uninstalled, reinstalled, etc.)  Finally clicked enhancement tabs on both Speakers and Realtek Digital Output, set digital output as default (what I use), and Disabled All Sound Effects.  It worked and I was able to play test tones and Sample Rates.  My audio codec is ALC 883.

Answer 13

The property key Deepak mentions is PKEY_Endpoint_Disable_SysFx.  This registry key is controlled by a checkbox in the Sound control panel:

Control Panel | Hardware and Sound | Sound | Speakers (or whatever the playback device's name is) | Enhancements | Disable all enhancements (check the box)

Audio drivers can provide their own UI for the Enhancements tab, but there is a logo requirement that there be a checkbox on the UI that disables all the enhancements.

4. Click on Properties (bottom right corner)

5. Go to the Enhancements Tab and Click on it

Answer 15

I have tried all of these solutions but nothing has worked.

My initial problem was when I purchased a usb headset. I plugged it in to use it but the sound keep coming through my computer speakers. I when to the sound properties and disabled the speakers and the sound came through my headset. But then there was a big red x on my computer speakers. I enabled the speakers but now i have no sound. I have tried everything and nothing is working. Everything appears to be working fine but when I test the speakers i get the failed to play test tone message.

i've tried restarting the Windows audio
I've tried the registry trick
I've tried the disable all sound effects trick.

I still have no sound. What else can i do. I am very close to throwing this computer out the window, lol

Answer 16

Goto the following key in registry.
HKEY_LOCAL_MACHINE  à SOFTWARE  à  Microsoft  à  Windows  à  
                                    CurrentVersion  à MMDevices  à Audio  à Render  à   
                                    {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} à FxProperties

In the right hand side of the registry window change the value of {1da5d803-d492-4edd-8c23-e0c0ffee7f0e},5  
(value type is REG_DWORD) to 1 (one) instead of 0 (zero).

INCASE YOU DON'T FIND THE ABOVE MENTIONED KEY UNDER fxproperties, PLEASE CREATE IT BY YOURSELF. (COPY & PASTE

{1da5d803-d492-4edd-8c23-e0c0ffee7f0e},5

TYPE IS REG_DWORD AND PUT VALUE 1

The audio start working at the moment you change the above value !!! (even before closing the registry editor).

No one has any idea?  Please, does begging help?  I have had a similar problem since 1/17/2010.  The above is my link.  "Failed to play test tone"

When I do a system restore to 1/10/2010 my computer initially works 100% fine.  However, windows request I reboot the computer to finish the restore/config/install.  As long as I postpone that reboot it works!  But, once I reboot nothing works.  If you need additional information please ask.  This might help multiple people,  I have a lot of info in my thread here.  This thread received 16,000 views.

Thank you very much

Answer 20

Ok, hello everyone who seems to having sound issues for the HP model a1410n. Lets go over a few basic issue troublesome tips for you on this model. First is BIOS> make sure in BIOS when your booting up that settings for BIOS is set on audio is not auto or disable> but enabled. Also when upgrading from the XP Media Center OS to > Vista (any) or Windows 7 (any) there a few BIOS flash updates you must run. I suggest backing up all your file before running a BIOS flash. Check the http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=1841799&lc=en&cc=us&dlc=en&lang=en&cc=us
select your OS type on current running. Find the latest driver for the realtek audio. Download to desktop or documents however you wish to do so.
Before running this driver update completely uninstall any audio drivers of the system. Check to also make sure you don't have any other type pf audio drivers installed from like the example Nvidia GT Galaxy 220 has a build HDMI HD audio. Just uninstall the Realtek driver. Before rebooting> run your current windows updates to see if maybe a recent patch is provided for such issues. Then if not or so reboot. After rebooting and checking to make sure your BIOS settings for audio is set for Enabled. Login to windows and install the driver. If the driver came into a winzip file> go to> start>computer> : right click my computer: > go to properties> device manager> find the [!] device for audio and open properties of that device. Then run update this device from winzip location or check for updated installed driver. I have a HP a1410n > using windows 7 64 bit. No issues for the audio. I did have to install a driver from windows 7 and HP to use it for the audio on mine is a Nvidia HD enchanced audio. Also for those who are running a 64 bit using any version of Vista and windows 7> the away mode has not been patched fixed yet. BIOS power settings should be SQL4 so when in stand by doesn't cause full system black shutdown.

Answer 21

Hey tony  don't know if you tried re-installing your windows but I just did that yesterday and I have sound. Isn't that crazy how long has it been with no real answers. If you haven't already try that and see if it works. I hope you have or will find success. Thanks!!!

Answer 22

I had this same issue today, and found the most bizarre fix

however I will quickly go over the problem:
 
Vista, with latest updates and driver for everything, no audio at all, getting failed to play test tone in sound devices, windows media player brings up an error when playing any file.

Tried:

I've tried
*  rebooting
*  uninstalling and reinstalling the driver for the sound card
*  "disable all enhancements" in the sound control panel
*  Registry fix: (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\DefaultAccessPermission)
*  Followed this: (http://www.consumingexperience.com/2009/04/failed-to-play-test-tone-no-sound-on.html)
* KBKB930883 and some other KB cant remember the number
My fix:

I decided that I was going to format and start again, so i went to my network and sharing center but found an error "network and sharing center server execution failed"

i figured this might have something to do with my problem so after i quick google i followed these steps

>>Right click "Computer"
>>Click "Manage"
>>Under the "System Tools" section, Double click "Local Users and Groups"
>>Click "Groups"
>>Right click "Administrators"
>>Click "Add to group..."
>>Click "Add"
>>Click "Advanced"
>>Click "Find Now"
>>Double click "Local Service"
>>Click "Ok"
>>"NT Authority\Local Service" should show up in the list now
>>Click "Ok"
>>Close Computer Management and reboot.

After my reboot my audio works again as well at my network and sharing center.

Hope thing brings joy to someone else :)

Robin Fleming

Answer 23

There wasn't a "Local Users and Groups" under the "System Tools" section. So I wasn't able to proceed with your solution. But in my case the issue got resolved after disabling USER ACCOUNT CONTROL. What a very unusual case.

Which solution worked for you to solve the audio problem ?

Answer 31

Deepak et al. - I'm a very technical guy and been struggling with this for three days now.   I knew it had to be permissions....the resolution that worked for me was adding the Local Service account to the Administrators group and then restarting the computer.   Nothing as sweet as hearing the start-up chime after making this change.   Thanks!

Answer 46

Hello Matthew -

my problem is pretty much exactly the same as those listed above...

I'm on W7, with a Soundblaster X-Fi card, and up until 2/15 everything was fine.  Then there was a windows update overnight, and when I logged in on the 16th, there was no audio on the computer.  All audio players returned error messages - even test tones wouldn't work. 

The soundcard was still fine in device manager - no conflicts - but the system would play no audio (and videos had a tremendous lag). 

I tried disabling/enabling, updating drivers etc etc...   I restored to the oldest point, which was 2/9, but the problem persists.  I backed out all the recent updates - but still no audio.

I would like to try Robin's solution above - but the network sharing and users/groups isn't accessible in W7.  (Boy do I miss windows 2k pro)

I was hoping that one of the users above who had success on Windows 7 would post the sequence.

Thanks,

THE SAME EXACT THING HAPPENED TO ME! 

Answer 49

Issue with new HP 8560p. Without updates and programs sound worked correctly.

Suddenly after a few days only sound with headphone. No sound via Speaker. Maybe after updates from Windows or installation of software.

Solution was for me:

Control Panel, Sound, right mousebutton on 'Speakers/HP'
 Properties, tab Effects
 Enable: Disable System Effects

Directly after this i have sound without rebooting the laptop.

THANKS A LOT ROBIN!!!!!

I was spending my last 3 days to solve "failed to play sound" issue. On my desktop volume icons were active but i couldnt get any system sounds. After this workaround i was able to get all sounds from my OS. Thanks a lot guys but does anyone have an idea about why adding local service to computer administrators was able to solve the problem??

Answer 53

Robin,

I tried this fix along with the same troubleshooting as you and it worked! Thank you!

Do you have any idea why your fix worked?

My techs are reporting that the sound works before said machine is put on the domain, once added, the sound doesn't work. This issue isn't on every image we are running, but a specific Vista 32-bit SP2 image. The network is closed so updates are locally administered. Once the local group policy is re-applied, Local Service is then removed from the Administrators group, but the audio still works.

Normally I would just tell my people not to worry about how I fixed it because it now works, but this is a secure network, so I have to give them something.

Any further input you could offer is greatly appreciated.

V/r,

Luke

Answer 54

this would have been great if only 7 home premium trusted me enough to make those changes. argh!

Neither thecraigmcrae's nor Robin's suggestions worked for me, but I thought I'd post instructions on how to add a user to the Administrators group for anyone with a Home version of Windows (as Local Users and Groups is not available).

Go to Start -> All Programs -> Accessories and right click Command Prompt.  Select "Run as administrator".  The command prompt will open.

Type in net localgroup administrators and hit Enter.  This will show you the users in the Administrators group.

Type in net localgroup administrators localservice /add and hit Enter.  This will add the NT Authority\Local Service user to the Administrators group.  To check, type in net localgroup administrators again.

Answer 55

After 2 days of suffering no sound, I found your fix.

Thanks a million.

Answer 56

thankyou so much, this is the only thing that has worked for me and i have spents hours and hours and hours to fix the problem. thankyou

Answer 57

First i disabled the speakers.

Then I clicked on the sound icon on the taskbar to start the sound diagonostic.

However I got the "Failed to play test tone" message again.

Then in the advanced tab of the speaker headphon properties dialog box I selected a different default format to test.

And then the problem was solved.

Answer 58

Thanks, this works for me... and was pretty easy without making the tedious restore hehe, Thanks again!

Answer 59

Before I could see an "Enhancements" tab in the speakers' properties, I had to roll back the driver (it had a 7/2012 date) which I did by selecting "Properties" from the "General" tab on the speakers' properties - "Controller Information" "Properties" - then selecting the "Driver" tab and choosing "Roll Back Driver". It required a re-boot. Then I could find the "Enhancements" tab mentioned.

Answer 60

Would all the people thanking someone for a solution please either quote the solution or state who it is they are thanking.  Otherwise the gratitude has absolutely no informational value to anyone.  I suppose after people hit reply to offer someone thanks they don't come back to see that it goes to the bottom with no clue as to whose solution it is.  This damn forum should be fixed so that doesn't happen (sub-threads aren't new or challenging technology) because it is a ubiquitous problem in virtually every thread.  But this is MS, after all.  Heavy sigh.

Among those that did receive actual attribution the most popular solution seems to be Robin's.  Anybody know how to effect that solution if you have Home Premium which has no "Local Users and Groups"?

>>Right click "Computer"

>>Under the "System Tools" section, Double click "Local Users and Groups"

Dead end.

Neither thecraigmcrae's nor Robin's suggestions worked for me, but I thought I'd post instructions on how to add a user to the Administrators group for anyone with a Home version of Windows (as Local Users and Groups is not available).

Go to Start -> All Programs -> Accessories and right click Command Prompt.  Select "Run as administrator".  The command prompt will open.

Type in net localgroup administrators and hit Enter.  This will show you the users in the Administrators group.

Type in net localgroup administrators localservice /add and hit Enter.  This will add the NT Authority\Local Service user to the Administrators group.  To check, type in net localgroup administrators again.

Thanks, asterismW.  This fixed it for me on Windows 7 Home Premium.  I sure wish I knew what suddenly made this necessasary.  Had me in a bit of a panic since this system is an audio workstation with gobs of unusual devices and software on board. 

FWIW, just prior I had installed Splashtop Streamer and accessed the system from my iPod Touch.  Uninstalling it didn't fix the problem and I can't blame Splashtop with certainty, but...

I had this same issue today, and found the most bizarre fix

however I will quickly go over the problem:
 
Vista, with latest updates and driver for everything, no audio at all, getting failed to play test tone in sound devices, windows media player brings up an error when playing any file.

Tried:

I've tried
*  rebooting
*  uninstalling and reinstalling the driver for the sound card
*  "disable all enhancements" in the sound control panel
*  Registry fix: (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\DefaultAccessPermission)
*  Followed this: (http://www.consumingexperience.com/2009/04/failed-to-play-test-tone-no-sound-on.html)
* KBKB930883 and some other KB cant remember the number
My fix:

I decided that I was going to format and start again, so i went to my network and sharing center but found an error "network and sharing center server execution failed"

i figured this might have something to do with my problem so after i quick google i followed these steps

>>Right click "Computer"
>>Click "Manage"
>>Under the "System Tools" section, Double click "Local Users and Groups"
>>Click "Groups"
>>Right click "Administrators"
>>Click "Add to group..."
>>Click "Add"
>>Click "Advanced"
>>Click "Find Now"
>>Double click "Local Service"
>>Click "Ok"
>>"NT Authority\Local Service" should show up in the list now
>>Click "Ok"
>>Close Computer Management and reboot.

After my reboot my audio works again as well at my network and sharing center.

Hope thing brings joy to someone else :)

Hi there, I have a problem with my sound system. I use a TOSHIBA Laptop. Do not know exactly what type it is but it has Windows 7.

My main problem is that I cannot play any sound (Failed to play test tone). I've tried almost everything that's written here. But no luck.
I've tried Robin's, but I had a problem in it. I couldn't find "Local Users and Groups" titled under the System Tools. I have tried the adding a local service which was mentioned before by asterismW, by adding a local service manually -->

"Go to Start -> All Programs -> Accessories and right click Command Prompt.  Select "Run as administrator".  The command prompt will open.

Type in net localgroup administrators and hit Enter.  This will show you the users in the Administrators group.

Type in net localgroup administrators localservice /add and hit Enter.  This will add the NT Authority\Local Service user to the Administrators group.  To check, type in net localgroup administrators again."

When I did that, the command prompt said it was successful, and I checked with typing "net localgroup administrators" and it does show another administrator called local service. But, when I tried Robin's, there were still no "Local Users and Groups" titled under the System Tools.

The cause of my laptop sound failing to work was because I was listening to music, specifically on Youtube, and I wanted a better sound so I clicked the sound icon on the bottom right corner, and clicked Mixer, then the speaker icon right above the title Speaker, and at the Enhancements I checked Bass Boost, Virtual Sound, and Loudness Equalization. I wasn't aware of what they would do if I checked them so I just decided to try and I clicked Apply. Then the real problem started. It was loading, and I waited, then I noticed it's taking pretty long, it said "(Not Responding)", then I waited for about a half an hour, took a look at it and it was still loading.  At that time, I had to go because I was in my office and I had to go home. So I decided to shut it down because I had to put it in the laptop case, and when all the programs are closing, the system showed me that there was one application waiting to be closed before it can shut down, it was the "Turning Off Sound.exe". I couldn't quite recall what it exactly said but I was sure the last program that needed to be closed was the turning off sound, and it had .exe on it. Then I waited for about 15 minutes and it hadn't shut off. I was impatient, so I held the power button to turn it off (Hard/Forced Shut Down) so I can put it in the case, and figured I'll deal with it at home. Then when I got home, turned it on and I knew windows would tell me whether to Start Windows Normally, or Start with Safe Mode. I chose Start Windows Normally. Then, I noticed something odd, when I entered my user account (there's only mine and a Guest), it didn't make a sound like it would usually do. Then I started to check the volume, wasn't muted, tried to maximize the volume, didn't make any sound. Then I tried testing it with the speaker properties, and it said Failed To Play Test Tone.

Now I don't know what to do, I don't wanna try restoring my laptop yet, maybe there are some of you who can help me with this problem. If there are details about this problem that you might want to know, please ask and I'll help you as I can.

Thank you.
Sincerely,
Ferris.
