Aborts in USB Audio. RRS feed

  • Question

  • Hi,

        I have a Working USB Audio Headset with UAC1.0 operating at full speed. The HeadSet configurations are 2 channel, 48KHZ.  HeadSet has internal loopback(playback buffer is connected to capture buffer). My goal is to play a wav file using Wasapi Exclusive mode and record the wav file using same mode and to verify the bit exactness of data. What i am observing is, the usb is sending and receiving isochronous data but in between it is aborting the requests. Every time i got an abort request, i am seeing mismatches in my recorded file. How to debug this ? Why aborts will occur in usb. I am windows 7. How can i proceed with this ?

  • Does the USB etw log have anything interesting in it?

  • Sry, The logman commands in https://blogs.msdn.microsoft.com/usbcoreblog/2009/12/04/etw-in-the-windows-7-usb-core-stack/ is not producing USB events. Can you please provide me the logman commands for etw in Windows 7.
