Hi.
## Problem, check symptoms
We have a laptop here affected by the problem.

2. Headphones output: no sound
3. Internal mic: works
4. Headset mic (no tested)
## Check workaround: success
> After testing please report back here what works (and what does not work) after issueing the 4 above commands;
> hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
> hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774
Issuing the first two above allowed to get sound output.
> hda-verb /dev/snd/hwC0D0 0x20 0x500 0x45
> hda-verb /dev/snd/hwC0D0 0x20 0x400 0x5289
Issuing the last two (right above) did not seem to have any effect.
Full test after the four commands:
1. Speakers: "perfect" sound
2. Headphones output: "perfect" sound
3. Internal mic: works
4. Headset mic: works
## Sound quality: as good as you can get
No artifacts like reported in #133.
"Perfect" means as good as can be given the physical speakers (e.g. not much bass but this is normal).
## Next step: have a permanent fix
Some copy-paste instructions as to how to make this fix permanent would be appreciated. Else I can figure out some and share, e.g. from https:/ /askubuntu. com/questions/ 919054/ how-do- i-run-a- single- command- at-startup- using-systemd
## Thanks
Thanks everyone, including @j-w-r-degoede who shows that kernel developers are taking care.
