[SOLVED] Sound chip not recognised

Hi,
I tried to turn my combo headphone/microphone port into a line-in port with HDAJackRetask. It did not work, and after I rebooted my laptop, I could not play or record anything with the internal speakers and mic.
alsamixer displays this

Chip: Generic ffff Generic

. Previously it was

Chip: Realtek ACL***

I tried reinstalling alsa-lib and linux to no avail. What should I do to fix this?

Re: [SOLVED] Sound chip not recognised

Start hdajackretask and click the disable boot override option.

Re: [SOLVED] Sound chip not recognised

Start hdajackretask and click the disable boot override option.

Did it. It says "No boot override is currently installed, nothing to remove." It should be that way since I never enabled boot override. Anyways, I wandered around the file system and noticed a few things. The file 'HDAJackRetask' used for overriding is '/sys/class/sound/hwC0D0/reconfig'. So I assume this 'sys/class/sound/hwC0D0' directory refers to my chip. These are the content of some files in it.
/sys/class/sound/hwC0D0/vendor_id:

0xffffffff

/sys/class/sound/hwC0D0/vendor_name:

Generic ffff

/sys/class/sound/hwC0D0/chip_name:

Generic

Looks corrupted right? Idk actually, I'm a total noob to this audio/kernel stuff. I'm desperate for help!

Re: [SOLVED] Sound chip not recognised

That's just the in kernel file system, that doesn't represent anything on disk. Let's see if you have any remnant files here:

stat /lib/firmware/hda-jack-retask.fw 
cat /etc/modprobe.d/*
#If you don't actually have these files, or modprobe doesn't read problematic
sudo fuser -v /dev/snd/*
sudo alsactl init

I'm not sure what specifically caused the problem or how it got resolved, but I just had to uninstall alsa-tools and reboot. Now everything is working fine. I had checked both lib/firmware/ and /etc/modprobe.d/ before and there was nothing related to hda-jack-retask. Anyways, the problem is solved now. Thank you so much for the help!
