Playing a sound from CLI


Apr 21, 2023
I'm trying to setup Proxmox to play some audio, I have a USB sound card attached to it, but an error is thrown everytime I try to play something. Any idea?

root@pve:/etc/pve# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: USB [Scarlett Solo USB], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
root@pve:/etc/pve# aplay a.mp3
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
aplay: main:830: audio open error: No such file or directory
