Hi,

I’m trying to use my 7.1 surround system on Arch Linux PC with pipewire. Currently 1 DP connected to the main monitor and 1 HDMI connected to the 7.1 sound system. Sound system has 4 HDMI IN and 1 HDMI OUT to the TV. First issue is without activating second monitor I can’t output any sound. Second issue is sound is always 2 channel. There are no other options on pavucontrol app. What i’m trying to achieve is

  1. Using only main monitor and outputting sound through HDMI to sound system

2. Outputting both video and sound through HDMI, which is working but only on 2 channels.

Thanks in advance

EDIT:

silly me, I changed HDMI cable and it detected all possible audio outputs including PCM 7.1

    Sometimes the solution is simply to replace broken hardware. It’s not always our first thought, although in many cases it should be. ;)
