http://code.msdn.microsoft.com/windowsapps/Basic-Media-Playback-003619be#content

I run the sample. Choose a video and play it. It plays normally.

Then I plug in my headphones. 

Sometimes the video not playing when the headphones plugged in. And the playback picture disappears.

Sometimes it happens when the headphones unplugged.

Any help is appreciated.

Answer 3

hi, Eric. Thanks for your reply. It still happens when I watching this video. And it shows “Errors: Video could not be decoded” when the headphones plugged in. Then I refresh the page, the video plays normally with the headphones.

Answer 4

Did you download the WMV or mp4 version of the video?

Answer 5

Also are these headphones a 3.5 mm jack, USB, Bluetooth?  Which computer are you using?

Answer 6

When I view the WMV version on a laptop and plug in a set of headphones using the 3.5 jack I do not see the issue.  What is your configuration?

Answer 7

If you play the same file from a local hard drive in Windows Media Player do you see the same behavior?

Answer 8

hi Eric, thanks for your reply.

These headphones are a 3.5 mm jack. 

The computer that I used is a product of our company.

If I play the same file from a local hard drive in Windows Media Player, it plays normally when the headphones plugged or unplugged.

Answer 9

Does the machine have a separate jack for the microphone and headphones?  Or simply one jack that is dedicated to a purpose or perhaps does both?  If it does both have you tried the splitter designed to work with it?

Answer 10

smilefishcc,

If your machine takes a splitter be sure to use that.  I believe the issue is a missing codec.
