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?
Meanwhile, I found there is another quirk ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, which looks like serving for a similar purpose, but with more stuff (e.g. bind-dac).
No, this issue was not the same. ALC274_FIXUP_DELL_AIO_LINEOUT_VERB ==> this lineout was true pin. Bios verb table can't fill this verb. So, it need driver to fill it.
OK, I'll add more information about that in the changelog.
thanks,
Takashi
