No Audio after blacklisting pcspkr

A few days ago I blacklisted pcspkr in /etc/modprobe.d/blacklist.conf, lost all audio, and since removed it and made multiple attempts to get audio back and working.

 $ lspci -vvv | grep Audio
07:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Renoir Radeon High Definition Audio Controller
07:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD] ACP/ACP3X/ACP6x Audio Coprocessor (rev 01)
07:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h/19h HD Audio Controller
 

 $ aplay -l

I've searched this forum and google far and wide trying to find some solutions and I've tried a few things:
I followed all of the instructions listed in the below forum:
https://bbs.archlinux.org/viewtopic.php … 4#p1888464
- I tried to downgrade the version of alsa-ucm-conf to 1.2.5-2 because I had read somewhere that there was a bug with version 1.2.6*  on thinkpad t14 AMD (my device).
- I tried unmuting devices in alsamixer
- I tried changing the default audio device in ~/.asoundrc
- Tried reinstalling sof-firmware

If I need to provide more system logs/outputs or any information, don't hesitate to ask.
Thanks for the help

Re: No Audio after blacklisting pcspkr

I highly doubt that has a relation. Any other modprobe files that try to manipulate audio module states? Post all of them, also post all your .asoundrc and /etc/asound.conf if present Output of

sudo dmesg | grep -iE 'snd|sof'
sudo fuser -v /dev/snd/*

generally you shouldn't follow the dmic_detect suggestion anymore assuming you have a device that's properly supported via sof-firmware and if you still have a file to that effect will lead to sof-firmware not being considered at all.

I don't have any other modprobe files, I have since deleted the ~/.asoundrc and have no file for /etc/asound.conf. I removed the dmic_detect as well.
For some reason, after being away from my laptop for a day, my results when I do `aplay -l` are different from when I posted it yesterday. See below:
