New arch installation: No sound output or input devices found [SOLVED]

I am trying arch for the first time. I just set up my laptop (Dell Inspiron 15 5000) with Arch + KDE plasma. Everything is working really well except for sound.

When I click on the muted speaker icon, it shows "No output or input devices found"

$lspci -v gives me

[teshan@mylap ~]$ pacmd list-sink-inputs

I can see that there have been multiple discussions related to the same problem. But none of them had a solution for my problem. Can someone please help me get this resolved? I don't have a clue to where to begin

Re: New arch installation: No sound output or input devices found [SOLVED]

You need to install sof-firmware as a basic requirement, ideally that should be all and it should just work after a reboot.

If you found that in "multiple discussions around the issue", it would be nice to mention what you tried already so we don't have to needlessly repeat ourselves. The last info I have on this is that this was pending on a kernel patch that should be part of the 5.15 kernels we are currently on

Re: New arch installation: No sound output or input devices found [SOLVED]

That worked! Thanks. Is this something I have missed from the setup process?

About the other discussions I found, I did not bother to post what I tried because every other post was mentioning losing sound after a while. And they all had their sound devices listed in fuser -v /dev/snd or pacmd list-devices

3rd bullet point, but it's very hardware dependent.
