No sound on Legion 7 speakers, Bluetooth headphones works

Hi, so I am having some problem with my sound on my Legion 7. I tried to update my kernel to 5.15 but that did not help. The sound will work on my BT headphones. and I can see that my PC picks up sound from firefox as I can see the soundbar moving in the settings window.

What do I need to do to fix this?

Probably some configuration needs to be done as not all system - internally - routes sound the same way.

Have a look at below page - especially the unmute section

I tried

amixer sset Master unmute                           1 ✘ 
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 65536 [100%] [on]
  Front Right: Playback 65536 [100%] [on]

That did nothing.

I also tried alsamixer. I turned everything on for both sound cards, that did not help.
I have never done this before so is there something else I need to try?

An amixer command without the card number is only capable of adjusting the default virtual audio controls for PulseAudio input/output levels

I suggest you get information about ALSA controls for onboard audio with this command

amixer --card=1

There was a similar issue happening with legion 7i (2020) and got fixed in recent kernel update after being debugged in https:// bugzilla.kernel.org/ show_bug.cgi?id=208555 . I think they are still trying to fix it for the 2021 model
