Comment 156 for bug 1850439

Thank you so much Sergey, Erikas and everyone involved in this thread! Thanks to your efforts I confirm that the four hda-verb commands work flawlessly to restore internal sound on UX534FA-A8093T (internally recognized as UX534FAC) with Intel Core i5-10210U on Solus OS. I just had to install alsa-tools and enter the four aforementioned commands.

What works:

- internal speakers (with good sound quality)
- headphones: both plugging in and unplugging while sound is working work as expected with sound being shifted to one or the other output flawlessly
- internal mic also seems to work (if I believe the sound meter in Sound settings) but it was already working before too I believe.

Do you think it's time to send an email to the kernel mailing list to try to get this fixed upstream? Before this fix I had tried without success another suggestion of patching kernel source file /sound/pci/hda/patch_realtek.c, so as to enable a preexisting quirk for our models. I got the idea from https://forum.manjaro.org/t/alc294-analog-audio-card-detected-but-no-sound-internaly-or-headphones/54089, it didn't work but surely as this is quite a common thing with Asus laptops, somebody up there in kernel land will be able to merge the proper fix?

If someone is already used to posting to LKML then please go ahead, otherwise I'll try to set up my email client so as not to trip off Majordomo ;-)

Thanks a lot again for the debugging work @Sergey & Erikas.
