So I’ve got a Dell XPS 9560 running openSUSE Tumbleweed with pipewire-pulseaudio
installed. At first everything was great, but then at some point I ran prime-select nvidia
and when I restarted, my audio devices were gone, and KDE says “No Audio Devices Found”. Running prime-select intel
doesn’t bring them back.
USB audio works fine, it’s just the on-board speakers and headphone jack.
running sudo lspci -nnv
gives me this for the audio controller:
00:1f.3 Audio device [0403]: Intel Corporation CM238 HD Audio Controller [8086:a171] (rev 31) (prog-if 80)
Subsystem: Dell Device [1028:07be]
Flags: bus master, fast devsel, latency 32, IRQ 17
Memory at ed128000 (64-bit, non-prefetchable) [size=16K]
Memory at ed100000 (64-bit, non-prefetchable) [size=64K]
Capabilities: [50] Power Management version 3
Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
So the system sees the controller and loads the driver. Running sudo fuser -v /dev/snd/*
outputs:
/dev/snd/seq: colin 1986 F.... pipewire
Running alsamixer
shows this:
At this point I’m pretty lost. I think maybe it’s related to the HDMI audio out from the 1050 chip in here, because like I said, selecting the Nvidia is what caused the issue to begin with, and because USB audio still works.
Any help of what to investigate would be appreciated?
