[SOLVED] Audio on proxmox (host)

[noobalaboomer]

Now it's strange... After apt update & dist-upgrade:
$ alsamixer ALSA lib confmisc.c:855:(parse_card) cannot find card '0' ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory ALSA lib confmisc.c:422:(snd_func_concat) error evaluating strings ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1334:(snd_func_refer) error evaluating name ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:5701:(snd_config_expand) Evaluate error: No such file or directory ALSA lib control.c:1528:(snd_ctl_open_noupdate) Invalid CTL default cannot open mixer: No such file or directory
I have no clue... Help, please...

I'm assuming you run that inside the VM? Maybe the audio device did not get number 0; try alsamixer -c1? I don't know how to configure stuff inside your VM, sorry.

Yes, that wai inside the VM. Problem is it doesn't recognize soundcard, but I can see it in lspci.

$ lspci | grep Audio 00:10.0 Audio device: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio (rev 03) $ aplay -l aplay: device_list:274: no soundcards found...

 

[noobalaboomer]

That's super crazy:

$ aplay -l aplay: device_list:274: no soundcards found... $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC671 Analog [ALC671 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0

This is from connection via ssh. Difference between the two is I additionally logged on VNC after first aplay -l.

Another crazy thing - after restoring backup (just after configuration of PCI device) and installing only alsa and snapclient, aplay behives the same, but snapclient works well and plays music w/o VNC and login.
