[SOLVED] [Alsa] Restore configuration when resuming from suspend

Nh3xus · 09-27-2014, 11:44 AM

Hi guys,

When I'm putting my laptop in suspend, my sound configuration is not restored when i wake my laptop up.

I would like to issue a command right after waking up my machine.

Like this one :

Code:

 alsactl -f /var/lib/alsa/asound.state store

Any tips on that ?

Hello,

I guess a script (executable) in /etc/pm/sleep.d should do the trick. Something like this :

Code:

case $1 in 
	resume)  alsactl -f /var/lib/alsa/asound.state restore ;;
	*) exit $NA ;;
esac

I think that you'll want to save the sound state on suspend too, otherwise you'll get back what was saved at last shutdown. I think that you want the configuration preserved unchanged through suspend.

Okay, I'm bumping this thread.

The script in /etc/pm/sleep.d did the trick.

Thanks you for that guys

However, after resuming from suspend, my multimedia buttons do not work anymore.

I'm no expert but, perhaps udev is preventing the Dell WMI hotkeys to work after a resume from suspend.

Any guidance on that issue ?

Cheers.

EDIT : For some reason, the Xfce mixer do recognize the multimedia buttons after X is restarted.

It's not very practical though.

Final update about this topic :

I've figured out how to fix my last problem.

In order for my multimedia buttons to work after resuming from suspend, I have to restart the xfce4-volumed daemon (as my user of course).

Both my built-in ones from my laptop and the ones of my usb headset works.

Again, thanks you guys for the guidance.
