Hey everyone! I recently installed Pop OS on my laptop and I'm having trouble with sound. It seems to be detecting no sound card, and I suspect it's a driver issue since this also happened when I installed Ubuntu on the same machine before. I tried installing the Sound Open Firmware (SOF) but didn't have any luck. Here are some relevant commands I've run and their outputs:
```
gabi@pop-os:~$ aplay -l
lsmod | grep snd
sudo dmesg | grep snd
```
I keep seeing messages like 'no se encontraron tarjetas de sonido...' (no sound cards found) and 'no codecs initialized.' I'd appreciate any help with getting my sound to work! Thanks!

Some sound chips require specific firmware, so it's a good idea to check using the command `dmesg | grep -i firmware`. If you see anything missing, you'll need to find the right package in your distro's repository. Let me know if you need help with that!
I ran that command and here's what I found:
```
gabi@pop-os:~$ sudo dmesg | grep -i firmware
[ 10.105589] i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/tgl_dmc_ver2_12.bin (v2.12)
[ 17.646472] iwlwifi 0000:01:00.0: loaded firmware version 29.f2390aa8.0 7265D-29.ucode op_mode iwlmvm
```
Not really sure what this means since I'm a bit inexperienced with Linux. Also, what do you mean by 'adequate package in your distro repo'? Thanks for your help!
