[SOLVED] Need help confirming if my soundcard is dead

I had sound working fine until yesterday when volume control disappeared from Polybar.
Running alsamixer produces the message 'cannot open mixer: No such file or directory'

I'm not really sure what diagnostic info I need to provide, but I ran the following and got these:

pacman -Q alsa-utils

alsa-utils 1.2.1-1

lspci | grep -i audio

00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

lsmod | grep -i snd

Re: [SOLVED] Need help confirming if my soundcard is dead

Hi,

I am having the same issue on my laptop.  It looks like a known bug in the new kernel.  I have been googling for a few days.  The only solution is fallback on the lts kernel for now.  My sound works perfectly on the lts kernel.

Thanks for pointing out its a kernel issue. Wouldn't have thought to look there.

It's been suggested on this thread to add the following to kernel parameters

snd_hda_intel.dmic_detect=0

I did so and sound is back on now. If you haven't tried that, give it a shot!

hey,

I know this is a stupid question.  I tried to run a systctl but it didn't work.  How did you add this to the kernel?  which file did you add?  thank you for your help.

Re: [SOLVED] Need help confirming if my soundcard is dead

You'll need to add the kernel parameter to the relevant entry for your bootloader. I use systemd-boot so mine looks like this:

/boot/loader/entries/arch.conf

title	Arch Linux
linux	/vmlinuz-linux
initrd	/intel-ucode.img
initrd	/initramfs-linux.img
options	root=UUID=426cf49d-82c2-4e71-9960-1c8451cc0ed2 rw nowatchdog quiet loglevel=3 rd.systemd.show_status=auto rd.udev.log_priority=3 nvidia-drm.modeset=1 snd_hda_intel.dmic_detect=0

This page has a list of the different boot managers. You can find the relevant wiki for your setup to see how to specify kernel parameters

Ah I understand this part.  I was sure if you need to add it in sysctl kernel parameter or boot.  Thank you very much.

Re: [SOLVED] Need help confirming if my soundcard is dead

Disabling it in a modprobe.d conf seemed to work as well.

[darose@darosevr tmp]$ cat /etc/modprobe.d/intel-audio-fix.conf 
options snd-hda-intel dmic_detect=0

One negative, though:  my internal microphone doesn't seem to be working - might be related.  Still looking for a fix on that.
