Hi,
I am trying to use this for a Proxmox LXC on my Raspberry Pi 4 based on this solution:
https://github.com/pimox/pimox7
This works fine, but in LXC containers I get no sound. Any idea what I could do to make this work?
What I did:
- Using Proxmox 7 (Pimox7) on Raspberry Pi 4 2GB ("HyperVi")
- Setup a privileged Proxmox LXC ("MediaCenter") via the web interface using a Debian template
- On the host, aplay sees my 2 HDMI connectors as audio devices and speaker-test gives an output through the speakers
- On the LXC, aplay does not see any audio device
HDMI "soundcards" are showing in the container under proc:
**nano /etc/pve/lxc/100.conf on the host:**
