Linux HTPC 5.13.11-1-MANJARO #1 SMP PREEMPT Sun Aug 15 13:15: x86_64 GNU/LinuxĠ0:00.0 Host bridge: Advanced Micro Devices, Inc. ![]() I’m running KDE plasma, on a Manjaro system that claims to be up to date. I know it is not hardware related, because the sound was working under KDE Neon with problems. The interesting thing is, when I do that, Plasma suddenly “sees” the hdmi sound card – but I cannot do anything with it. I have tried using aplay, the only hardware device the responds is 0:3, but no sound comes out – it just locks up, and I cannot kill it. It is almost like something else has the sound monopolized… but with pipewire out of the way, I don’t know what that could be. I installed pavucontrol, but it never seems to be able to connect to the pulse server (even though I see it running in the background). ![]() I’ve confirmed that all channels are unmuted in alsamixer. I’ve disabled pipewire, I’ve ensured pulse is running, I set up an /etc/pulse/nf file. The sound is going out the HDMI on the back of my nvidia card. I installed this two days ago, and have been fussing ever since.
