Hi
We have implemented two audio mini drivers for Bluetooth using AVStream, One
for Handsfree ( communication device i.e With render and capture pins) and the
other for music streaming ( playback device i.e with Render pin).
Both the drivers works fine individually i.e audio streaming and skype call
works fine. But we have a problem in the below mentioned scenario.
1. Music streaming through playback device. Pause the streaming
2. Start a skype call, it uses communication device ( Handsfree).Accept the
call.disconnect the call
3. Resume the music streaming from Windows Media Player. Audio is noisy. But if
we change the track / close and open the media player, audio is perfect.
This issue is seen only after disconnecting the call, otherwise pause/resume
works fine.
This issue is seen only on Windows 7.
I have tried disabling the playback endpoint for a short while using
KsFilterFactorySetDeviceClassesState. But didnt help.
Any pointers on how to debug this would help.
Thanks
Girish
