Hi everybody,
I recently bought the laptop. It has one jack for attaching a headset. Jack
sense is announced by the HDA config but not working. Except for some
positioning, and color information, the PIN config seemed to be sensible, and
everything I tried to override, didn't result in a working jack.
Manually unmuting the jack using hda-analyser resulted in working output, so
generally the config seemed to work.
Reading the patch-realtek code, if found ALC256_FIXUP_ASUS_HEADSET_MODE, which
somehow changed the pin 0x19 to be associated with the 0x21 headset out pin,
resulting in this dmesg change:
-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
And for whatever reason jack sense is now working, at least for some normal
output-only headset (currently I don't have one included a mic with me, so
actually can't test that mic volume works correctly).
I was just wondering, if my pin values are actually correct, because they still
define different association, as I understand it, but the ASUS fix even works
with these wrong channels /associations 2 and 4.
So the attached patch works for me, but I'm still wondering, if this is the
correct solution. FWIW, jack sense works fine in Windows.
Anything I might be missing here?

Subject: [PATCH] ALSA: hda/realtek: PCI quirk for Medion E4254
The laptop has a combined jack to attach headsets on the right.
The BIOS encodes them as two different colored jacks at the front,
but otherwise it seems to be configured ok. But any adaption of
the pins config on its own doesn't fix the jack detection to work
in Linux. Still Windows works correct.
This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
which seems to register the microphone jack as a headset part and
also results in fixing jack sensing, visible in dmesg as:
-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
