Comment 134 for bug 1851518

FYI - I have the NP950XEE (GalaxyBook2 Pro w/ Intel ARC graphics), have been struggling with the same problem and trying to fix for days now. I have perfect sound in headphones, no sound on speakers. I've implemented every fix discussed here, and haven't seen one single effect. I'm running 22.04. I tried upgrading kernels to 5.17 and 6.0 also, no effect. No matter what I try, headphones work, speakers not (and no metallic sound on headphones). Can anyone give any help/guidance, I'm stuck.
