HDMI alsa Sound
« on: 2022/01/15, 12:26:07 »
Hello- while setting up the actual Siduction Repo (Wintersky-KDE) on a Shuttle DS81 mini-pc I got the problem having no sound on a HDMI connected TV. When I switch playback in Pulse from onboard- Soundcard hda-Intel- ALC-892 to HDMI playback stops in any software system wide. I've research the internet for any solution where I could read that this problem often appears with some laptops (HP, and other) but with no success. The system is a Haswell corei 4700 series with Intel- H81 chipset.

In Detail:

Also fixes like the grub starting parameter "intel_iommu=on,igfx_off" doesn't help

The next I'll try is to install an older Repo with older kernel than 5.15.14-1-siduction-amd64. What I've found is that some people has reported trouble while upgrading to "Bullseye".

Is anybody out there having a hint or solution to fix that problem?

After a long time of not being able to check out further investigation on this issue I've found the solution in the internet today. The problem I can't get any sound out off the HDMI- port connected TV is intel_iommu for me too. While giving grub2 the kernel-parameter intel_iommu=igfx_off before booting the system sound-output on a connected TV via HDMI is working now!!  ;D

So the problem is solved!
