[regression] ctxfi: no speaker output when headphones connected on >=7.0.x

[regression] ctxfi: no speaker output when headphones connected on >=7.0.x

[Thorsten Leemhuis]

Hi! Just FYI, I noticed a regression report in bugzilla:

https://bugzilla.kernel.org/show_bug.cgi?id=221461

See the ticket for more details. One of them: 7.1-rc2 is affected as
well. Reporter is CCed. Forwarded this to ensure this report makes it to
the interested parties, as bugzilla might not have forwarded this.

Dutch Ingraham: if nobody within a few days has an idea why this
happens, you will likely have to use a git bisection to get this resolved.

Ciao, Thorsten

As there have been many significant changes in ctxfi since 6.18, it's
hard to tell what broke.  Please go git bisect.

Creative Sound Blaster Z-series uses the snd_hda_codec_ca0132 driver,
not snd_ctxfi. The dmesg logs in the bugzilla shows only ca0132
entries.

Ah, sorry, then it's easier.  The only major change is the
commit 778031e1658d206a52bf9491c91ae5d4f4a2509d
    ALSA: hda/ca0132: Set HP/Speaker auto-detect default from headphone pin verb

Try to revert this one.

I can confirm this seems like a good candidate. I built and tested 6.19.14
and 7.0. On 6.19.14, speakers work as expected; on 7.0, speakers are not
working as expected and the offending patch is included in the 7.0 patchset.

Thank you all for your work on this issue.

OK, then let's put Matt to the party.
Matt, could you help for debugging the regression?

I can confirm the regression here on my 2013 Chromebook Pixel w/CA0132.

Looking more closely, the issue is that tVNID_HP_ASEL and VNID_HP_SEL are
mutually exclusive selection sources in ca0132_select_out() /
ca0132_alt_select_out(),
and auto-detect always "wins." So, enabling auto-detect effectively
disabled user
override.

While reverting would fix this problem, it would reintroduce the
problem of jack-detect being
ignored completely. A better solution would be to default to
auto-detect, but allow manual selection
to override. Here's a quick patch I whipped up that should resolve the
issue (untested though):

Subject: [PATCH] ALSA: hda/ca0132: Disable auto-detect on manual output select

Commit 778031e1658d ("ALSA: hda/ca0132: Set HP/Speaker
auto-detect default from headphone pin verb") enables HP/Speaker
auto-detect by default when the headphone pin supports presence detect.

With auto-detect enabled, ca0132_select_out() and ca0132_alt_select_out()
choose the output from jack presence instead of the manual HP/Speaker
selection. This means selecting speaker output while headphones are
plugged in updates the control state, but audio still routes to the
headphones.

Treat an explicit manual output selection as a request to leave
auto-detect mode. Clear the HP/Speaker auto-detect switch before applying
the manual selection, and notify userspace so the auto-detect control
state is updated in mixers. Do this for both the normal HP/Speaker
Playback Switch and the alternate Output Select control used by desktop
cards.

This keeps auto-detect enabled by default for devices with jack presence
detection, while preserving the expected behavior that a manual output
choice takes effect immediately.

Fixes: 778031e1658d ("ALSA: hda/ca0132: Set HP/Speaker auto-detect
default from headphone pin verb")

It looks like that the patch is malformed by your mailer.
For avoiding unneeded troubles, please fix the setup or give an

My apologies, forgot to ensure text-mode sending when I replied.
Hopefully better this time.

Subject: [PATCH] ALSA: hda/ca0132: Disable auto-detect on manual output select

Commit 778031e1658d ("ALSA: hda/ca0132: Set HP/Speaker
auto-detect default from headphone pin verb") enables HP/Speaker
auto-detect by default when the headphone pin supports presence detect.

With auto-detect enabled, ca0132_select_out() and ca0132_alt_select_out()
choose the output from jack presence instead of the manual HP/Speaker
selection. This means selecting speaker output while headphones are
plugged in updates the control state, but audio still routes to the
headphones.

Treat an explicit manual output selection as a request to leave
auto-detect mode. Clear the HP/Speaker auto-detect switch before applying
the manual selection, and notify userspace so the auto-detect control
state is updated in mixers. Do this for both the normal HP/Speaker
Playback Switch and the alternate Output Select control used by desktop
cards.

This keeps auto-detect enabled by default for devices with jack presence
detection, while preserving the expected behavior that a manual output
choice takes effect immediately.

Patched against originally non-working v7.0. Now, works as expected; can
choose Line Out / Speaker or Line Out / Headphones and default holds
across reboots.

Thank you Matt and all others who gave your attention to this issue.
