Re: [alsa-devel] HP 6930p mute button/led out of sync; fixed by suspend/resume cycle

Hi,
I experience an odd issue with my HP6930p laptop.
After boot pressing the mute button/led causes the audio to be muted but the sate is not reflected in software (i.e the mixer does not show the control as muted). However pressing after a suspend/resume cycle it works as expected. The hardware mute button/led and the software control are in sync (pressing the hw button toggles the mixer to mute/unmute; muting the software mixer results into the led turning red).
This was with 2.6.31.9 and 2.6.32.1; also installing alsa-drivers from source does not change this.
It seems something is not initialized correctly during boot up but is done on resume, any pointers on how to debug this?
(Resending to correct list)

First off, give alsa-info.sh output (run with --no-upload option) on the very latest alsa-driver. The mute LED is usually controlled via GPIO 3 or GPIO 1 on HP machines according to the codec chip.

Takashi

Hi,
Sorry I somehow missed this mail.
I have created a bug report in the meantime: http://bugzilla.kernel.org/show_bug.cgi?id=15176
Which does contain alsa-info.sh output before and after suspend.
If you require any other info please ask.
We can move the discussion to the bug if you prefer that.
Thanks

Could you try sound git tree? git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
Take either master or topic/hda branch.
thanks,
Takashi

The behavior is unchanged in sound-2.6.git
alsa-info output is attached.
