Hi Takashi,
This platform was only one phone Jack.
Add dummy lineout verb to fix automute mode disable.
This just the workarround.
I'm not sure why this phantom line pin is needed.
What happens without that?
Looks like I find the root cause for this issue, since
there is only one output device (headphone）， so the Auto-mute
is not supported on this machine, as a result, when users
plug headphone to the jack, audomute_hook or hp_automute_hook
will not be called, then the alc_update_headset_mode() will
not be called, and alc_headset_mode_default() will not be
called. the headset jack is always in the
alc_headset_mode_unplugged() state.
OK, now understood.
I can take the patch as a tentative workaround.
But for the proper fix, could you give alsa-info.sh output?
I had no machine in my site.
Hi Hui Wang,
Could you help to send alsa-info.sh output to Takashi?
OK, I will collect the alsa-info.txt tomorrow.
Regards,
Hui.
thanks,
Takashi
