Thread-topic: Re: Enable audio virtualization in Xen

[AMD Official Use Only - General]

Hi all,

Forgot to mention that I am able to play audio from HVM guest with Pulse Audio as back end. Here is the corresponding HVM configuration:

vsnd = [[ 'card, backend=Domain-0, buffer-size=65536, short-name=VCard, long-name=Virtual sound card, sample-rates=44100, sample-formats=s16_le', 'pcm, name=dev1', 'stream, unique-id=pulse, type=P' ]]

I have used xen front end and snd_be (along with libxenbe) as back end as suggested by Christopher earlier in this thread.

Only when I change unique-id=alsa, audio is not working from HVM guest.

If anyone has tried ALSA back end (instead of PA), please let me know what I am missing.

Regards,

Jyotirmoy
