[Regression] No sound on HP Pavilion dv6, STAC92xx

[Regression] No sound on HP Pavilion dv6, STAC92xx

[Luis Henriques]

Hi,

After commit b0791dda813c179e539b0fc1ecd3f5f30f2571e2 ("ALSA: hda/idt
- Fix power-map for speaker-pins with some HP laptops") we have
several bug reports about not having sound on HP Pavilion laptops.

Here's a link to one of these bug reports:

 http://bugs.launchpad.net/bugs/1013183

After reverting the referred commit, everything seems to be working
fine again.

Any ideas/fixes?

Cheers,

Could you give alsa-info.sh output on both working and non-working
kernels?

You should be to get the same information in the bug URL.  But I'll
try to get that info using that script from one of the bug reports.

It's not same :)  Many information are missing, e.g. sysfs pincfgs.
alsa-info.sh output contains the whole information in a single file,
and above all, it can be fed to hda-emu for analyzing the problem.

Also, does it really happen with the upstream kernels (vanilla 3.2.y
and Linus tree) without ubuntu changes?  If yes, I'd need alsa-info.sh
outputs on these, too.

Never mind, I found the culprit.
The fixed patch for 3.5 kernel is below.

For 3.4 and older kernels, another patch is necessary.  Will put in
another post.

Subject: [PATCH] ALSA: hda - Fix power-map regression for HP dv6 & co

The recent fix for power-map controls (commit b0791dda813) caused
regressions on some other HP laptops.  They have fixed pins but these
pins are exposed as jack-detectable.  Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.

This patch adds the check of connection and it assumes the no jack
detection is available for fixed pins no matter what pin capability
says.

Below is the patch for 3.4 and older.

From: Takashi Iwai <tiwai@suse.de>
Subject: [PATCH] ALSA: hda - Fix power-map regression for HP dv6 & co

commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 upstream.

The recent fix for power-map controls (commit b0791dda813) caused
regressions on some other HP laptops.  They have fixed pins but these
pins are exposed as jack-detectable.  Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.

This patch corrects the condition check for fixed pins so that the
power-map is set always for these pins.

NOTE: this is no simple backport from 3.5 kernel.  Since 3.5 kernel
had significant code change in the relevant part, I had to fix this
differently.

Just to let you know that we are receiving positive feedback on this
patch from the bug reporters.

I believe you plan to Cc: this patch to -stable, right?  We had this
issue reported against 3.2.y.

It's not Cc'ed because it cannot be cherry-picked.  I'll post the
patch to stable ML once after the upstream fix is merged to Linus
tree.

Great, thanks a lot for your help.  I was trying to gather the data
from bug reporters, but I guess I can abort that.

I'll try to get someone testing the patch.
