[PATCH] ALSA: hda - Fix Dock Headphone on Thinkpad X250 seen as a Line Out

[PATCH] ALSA: hda - Fix Dock Headphone on Thinkpad X250 seen as a Line Out

[David Henningsson]

Thinkpad X250, when attached to a dock, has two headphone outs but
no line out. Make sure we don't try to turn this into one headphone
and one line out (since that disables the headphone amp on the dock).

This is one of fixes I had in mind (and asked for testing in bugzilla
kernel.org report).  One drawback by this is that the auto-mute
*between* the headphones won't work like before.  If one has expected
it, then this can be seen as a regression.

Another fix was to change this as a proper line-out.  This will keep
the current auto-mute behavior.

OTOH, dealing both jacks equally is also not bad, per se.

Sorry, I'm missing context. What report?

Fair enough, we can drop stable from the patch since this could be seen 
as behavioural change rather than bug fix.

The tricky thing about routing is that everyone wants it different, so 
pleasing everyone seems to be an impossible equation :-/

I would choose the default behaviour (headphone or line out) based on 
the icon on the jack. I should double-check that with someone who has 
the hardware. And then, if someone wants another behaviour then 
hdajackretask can be used. Or we can add a jack mode kcontrol for that 
jack, if you prefer, although I'd have to check how PulseAudio handles 
that (not that well, is my gut feeling).

Thanks.

So headphones should automute between each other if and only if both of 
them are combined headset jacks? Or what do you suggest?

I have no preference in this regard.  My only slight concern was the
behavior change by this patch.  It has both sides, one can see as an
improvement while another as a regression.

Currently I'm inclined to take this patch as is, since this would make
things working in a little obstacle.  Once when we get a real
regression report due to the lack of exclusive mute control, we may
provide another model option as a compromise.

But, I'm open about this, really.  So, if anyone has a good argument,
let me know.


thanks,

Takashi

Anyhow, it looks like the current behaviour is not good, because we have 
a "Dock Headphone Jack" on the same node as "Dock Line Out Playback 
Switch". This makes me wonder if the HP -> LO fixup should be removed 
altogether. Are there any machines these days that needs this fixup? In 
case there were just a few of them in the past, maybe they should have 
pin fixups instead?

Yes, this is one good step forward.  We should check through hda-emu.

Though, for the problem of Thinkpads, I prefer a patch with a smaller
impact like yours.

FYI, I applied the patch now.  Let's continue working on top of it.
