[AMD Official Use Only - General] 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? 01.09.22 12:46:37.240 | Main | INF - backend version: v0.2.1-6-gb276 01.09.22 12:46:37.240 | Main | INF - libxenbe version: v0.2.1-11-g2e55-dirty 01.09.22 12:46:37.240 | XenStore | DBG -
