ALSA: hda/realtek: Audio disappears on HP 15-fc000 after warm boot again
There was a similar bug in the past (Bug 217440), which was fixed for
this laptop.
The same issue is occurring again as of kernel v.6.12.2. The symptoms
are very similar - initially audio works but after a warm reboot, the
audio completely disappears until the computer is powered off (there
is no audio output at all).
The issue is also related by caused by a different change now. By
bisecting different kernel versions, I found that reverting
cc3d0b5dd989 in patch_realtek.c[*] restores the sound and it works
fine after the reboot.
