The amplifiers are “i2c” device, see: Instantiating i2c devices. Not surprising that they aren’t supported. Integrated amplifiers are used in laptops, but these are likely more powerful, so IMac 21.5 inch 2017 Retina teardown says “Texas Instruments TAS5764L audio amplifier”. Sound cards have been problematic in linux over the years, so I have a couple USB audio devices, one a small dongle with a headphone jack and one with RCA and TOSLINK optical connectors for use with an external amplified and much better speakers. snd_hda_macbookpro issue 11 describes what is needed to suss out the amplifier details if you can’t find them on the web. I wonder if your audio amplifier isn’t known to linux. Spent several hours shovelling snow, which gave time to for odd corners of my memory to wake up. Yes this is a fresh install of Fedora 37 on bare metal (almost because there is a bug in F37 installer, I had to install F36 then upgrade to F37 like explained here).

This topic seems to be similar, but it points to this kernel module which I don’t know how to use. Most topics don’t provide a solution (ie on ask fedora /t/intel-audio-issues/19370/32).
