Dear Volker,

do you still need help with this issue? I think I can reproduce the error. It's a alsa-lib configuration problem.

Yes, I still need help!


On my system I see errors similar to yours, if I start qemu as a different user than my currently logged in user. To hear audio with ALSA I specify the audio device to use on the command line. Here is an example for my system:

-audiodev alsa,id=audio0,out.period-length=5000,out.dev=hw:1,,0,in.period-length=5000,in.dev=hw:1,,0

The first number after hw: is the card number and the second the device number. To list your audio devices use aplay -l and arecord -l. Please note the doubled ,, to pass a single , to alsa-lib.

With best regards,
