No sound on Gemini Lake

Installed Arch and pavucontrol only showed "Dummy Output". Researched a bit and saw on alsa wiki page that I have to install alsa-ucm-conf and sof-firmware. Installed both. Now speakers and headphone appears on pavucontrol, but still no sound.

lspci | grep Audio

gives the following output:

00:0e.0 Multimedia audio controller: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio (rev 06)
sudo dmesg | grep -iE "snd|sof|audio"

gives the following output:

Tried installing sof-firmware from sof project github repo, but it also didn't work.

Tried solutions in this post, but none worked.

Re: No sound on Gemini Lake

As mentioned in that thread this currently doesn't work, if you want to actively help report a bug to the sof project.

Re: No sound on Gemini Lake

Managed to fix it. I just changed my default sound card on ~/.asoundrc as the mic of the webcam is recognized as another sound card and is selected as default. Then, I ran all the commands listed here and the audio worked fine.
But I still have a loud crackling noise from speakers during login and if I boot with headphones connected, the audio outputs from the speakers and I have to disconnect and connect the headphones again.
