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:

I'm running Proxmox VE here as a full desktop env with Plasma, and the sound works right out of the box. I've never tried this on a server without a GUI.
But you could try configuring it with alsamixer, maybe that'll help:

Code: 
apt install alsamixergui

Then run "alsamixer" from the CLI.
 
Hello,
I installed alsamixer. When I chose
Card: HD Audio Generic / Chip: Realtec ALC662 rev3
and do
Code: 
aplay -D plughw:CARD=Generic,DEV=0 /usr/share/sounds/alsa/Front_Right.wav
then i get Sound on the Speaker out.
No Sound over HDMI/DisplayPort

When i Change in alsamixer to Card: HDA ATI HDMI / Chip: ATI R6xx HDMI
Sound on the Speaker ist stil working an no sound over HDMI/DP

When i start a Linux Mint Live CD ich can choose HDMI/DP output in the Sound settings and it works.
 
Well, that sounds good. So it works with the built-in sound card, but not via HDMI. You can select HDMI, but there's no sound. And I'm guessing the corresponding controls are set to ON? These things are often muted.

Is there anything helpful in the journal?
