Request for HW auto-recognition: HP Pavilion dv7 with STAC92xx

[Tomas Pospisek]

Hello,

I have a HP Pavilion dv7 laptop (LS066EA#UUZ), with:

  # cat /proc/asound/card0/codec* | grep Codec
  Codec: IDT 92HD81B1X5
  Codec: Intel CougarPoint HDMI

when play sound without any tweaks, I get a very weak sound output. If I
want to have "beats audio", that is subwoofer and all speakers, I need to
set:

  # cat /etc/modprobe.d/alsa-base.conf 
  options snd-hda-intel model=hp-dv7-4000

Could the snd_hda_intel alsa driver be updated to recognize and setup the
driver accordingly?

alsa-info.sh output here:

Thanks,

Could you check whether the patch below works?

It now indeed does switch on "beats audio" aka subwoofer et al.

However now I got a different problem: When I play a video on youtube,
then
suspend to RAM, and then resume:

* if the music was playing when suspending, then the desktop gets stuck
  after resume:
  no mouse, no keyboard input gets through to the desktop. I can
  Ctrl-Alt-F1 out of X and reboot and that's it. I guess it's the firefox
  flash plugin getting blocked in the kernel while accessing the audio
  device and thus blocking the whole desktop (that's my speculation).

* if the music was *not* playing (i.e. video paused), then after resume
  there is no sound any more. "alsa force-reload" puts the audio in some
  weird state where it gets in a loop playing some short bit of sound:
  tak-tak-tak-tak-tak-tak... So again I reboot.

OK, I'm going to queue the fix later.

Is it a regression from 3.6 kernel?
If so, could you try to bisect?

Possibly it's a regression due to the runtime PM support.  Other than
that, I have no clue yet.
