Hi Oleksandr, Christopher and others,
I am trying to enable audio playback from HVM guest as per discussion above using ALSA as back end.
I have compiled and installed libxenbe (https://github.com/xen-troops/libxenbe) and snd_be (https://github.com/xen-troops/snd_be).
Following is my vsnd detail in the HVM configuration file:
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=alsa<default>, type=P' ]]
Here is the virtual card listed in HVM guest:
amd@amd-HVM-domU:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vsnd [], device 0: dev1 [Virtual card PCM]
Subdevices: 0/1
Subdevice #0: subdevice #0
I am trying to play audio in guest HVM using aplay command: aplay sample.wav. However, I am not able to hear any audio in this case.
Please note that if I play the wave file from dom 0 using the same command, audio can be heard. This means that audio is working fine in the dom 0 using default card.
Below is the log from snd_be. Has anyone tried ALSA back end before? If yes, can you help me in understanding the issue here?
