There is a problem with simultaneous audio output to headphones and

However, it was found that if you boot linux immediately after
windows,
there are no such problems. When comparing alsa-info, the only
difference
is the different configuration of Node 0x1d:
working conf. (windows): Pin-ctls: 0x80: HP
not working (linux): Pin-ctls: 0xc0: OUT HP
This patch disable the AC_PINCTL_OUT_EN bit of Node 0x1d and fixes the
described problem.
Though this is already applied, is it possible to see if the issue
also happens on S4?
Linux doesn't put PCI devices like HDA to D3 during shutdown and
reboot while Windows does, that might be the reason boot Linux after
Windows can workaround the issue.
Linux does put PCI devices to D3 for hibernate (S4), so we can use it
as an experiment.
Right, it should have been the cached version so that the setup is
reapplied automatically; i.e. replace snd_hda_set_pin_ctl() with
snd_hda_set_pin_ctl_cached().
Vasiliy, care to test and submit an incremental fix?
Ok, I compiled the module with the proposed changes and sent it to the
user for testing on a machine with this codec. After testing, I will
write about the result.
Using the snd_hda_set_pin_ctl_cache() function instead of
snd_hda_set_pin_ctl() leads to the same positive result, there are no
problems with sound. The patch has been sent [1]
