No sound output

So I recently re-installed arch on my computer and the sound was working completely fine before but for some reason I can't seem to be able to enable sound on my machine. Alsamixer shows only S/PDIF with no sound controls.

lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04)

Re: No sound output

Potentially moved over to sof firmware in current kernels:  https://wiki.archlinux.org/index.php/Ad … A_Firmware

check dmesg | grep sof if that lists the card wants to be detected as sof you'll need the sof-firmware and alsa-ucm-conf packages.

Re: No sound output

I tried installing sof-firmware and alsa-ucm-conf but it still doesn't work. Any suggestions on what should I do, I've read through the wiki but couldn't find a solution there as well. I've been struggling with this for a week now.

dmesg | grep sof
[    0.273249] PCI-DMA: Using software bounce buffering for IO (SWIOTLB)
[    0.273251] software IO TLB: mapped [mem 0x0000000096abf000-0x000000009aabf000] (64MB)

Re: No sound output

If you don't get any other output here you don't have a SOF card so you'll want to post more general information, do you use pipewire/pulseaudio?

sudo dmesg | grep snd
sudo fuser -v /dev/snd/*
aplay -lL
amixer -c0 #Or whatever card you intend to have output from
pactl list cards
pactl list sinks

post these in [ code ], not [ quote ] tags

I do have pulseaudio installed with pavucontrol but pavucontrol shows only dummy output. Never tried pipewire/jack

Re: No sound output

Mhm... I'd expect more in that dmesg at the least. Do you have any snd_hda_intel module parameters? On which kernel did this work last (... test LTS)? Do you have a Windows dual boot? One thing that pops to mind ehre might be some issue with the codec initialization try a

sudo alsactl init

for what reason did you reinstall? Was a BIOS/UEFI update involved, have you checked there on whether the integrated audio is disabled?

Re: No sound output

sudo alsactl init
alsa-lib parser.c:260:(error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0xd1810000 irq 34)
alsa-lib main.c:1014:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6

Hardware is initialized using a generic method

I had a corrupted partition which i was unable to fix, so i reinstalled my arch.
There was no BIOS update involved and i think the sound was working in the kernel 5.10, stable

Re: No sound output

hmm, though there's no obvious evidence towards it the fact that it tries to mess around with UCM here might still be a teller that it does try to do something with SOF/SST here.

Create a file /etc/modprobe.d/dspfix.conf

options snd_intel_dspcfg dsp_driver=1

and reboot.

Re: No sound output

Just rebooted, nothing's changed.

I wonder if there's a problem with the hardware itself
