Hello,
i am using Proxmox on an Igel M340C Thin Client / UD3-LX 50 / GX-424CC SOC with Radeon(TM) R5E Graphics (1 Socket).
VT in Bios is enabled and i can run "Normal" VM's.

The goal is to get Sound output on Display Port running in a unprivileged Container running Linux Mint (Lyrion Music Server and Squeezelite Client running there).
For testing i connected a Monitor with Spakers.
My problem (at the moment) is NOT to "provide" the /dev/snd stuff to the container - i did read all that.
According to some posts and my logic i should get running the sound within proxmox at first.
I do not get it running.
BTW - tried it on the front speaker out jack.
Here some outputs - I do not know what might help to identify the problem:
