No sound from speakers, but headphones work 22.04

I have a Raider GE78HX13V and Ubuntu 22.04 LTS installed. One day the sound from the speakers was just gone (can't say for sure what the cause was). But now there is a sound from headphones but not from speakers. I've tried to reinstall the services. Also, there is an indicator showing that sound is here. I've also tried to boot from USB, all the same. The laptop is 6 months old but now I think that it can be a hardware problem... Any help will be appreciated.

Edit: BIOS updates haven't made it any better...
