How to access VLC container to use alsamixer?

Installation
1

Hi,

I’ve installed up-to-date HAOS in a VM on an up-to-date Proxmox host and passed through a Focusrite Scarlett 18i20 USB audio device.

After installation MusicAssistant sees the VLC player and starts playback but without sound from the 18i20. The sync-lock LED of the 18i20 is off. I assume a mis-configuration of ALSA in the VLC container (maybe using TOSLink/ADAT as clock source instead of the internal clock?).

How can I access the VLC container to use alsamixer directly on the hardware instead of Pulseaudio in the Homeassistant container?

Thanx for any hint! :smiley:
