No sound after resuming from suspend/hibernate

**Antioch** · May 12th, 2009

I'd like to know this as well.

Also, in my case after resume the USB keyboard doesn't work. I have to plug it into a different slot before I can use it again... and ideas?

There are directions for getting alsa to automatically restart after resume.

Enjoy!

Anyone else had success?

Just tried this and it works - awesome!

Heyas,

I came across this thread through Google as a new user of Ubuntu searching for a fix to the same issue. I have similar hardware to the OP, Jephir:
Motherboard: Asus P5K
Soundcard: Xonar DX
with an E6420, 8800GTS

As above, the link provided by Antioch enables you to reload ALSA after suspending your computer. I was having problems getting it to work, as you additionally need to enable 'Allow executing file as a program".

Here's the full instructions with the added last step:

Open a terminal then run the command below

Code:

sudo nano /etc/pm/sleep.d/50alsa

(Or gedit/whatever other text editor)

Copy and paste the below code then save and close the file

Code:

case "$1" in
        hibernate|suspend)
                # Stopping is not required
                ;;
        thaw|resume)
                /sbin/alsa force-reload
                ;;
        *) exit $NA
                ;;
esac

Now run in the terminal

Code:

sudo nautilus /etc/pm/sleep.d

Right-click on the 50alsa file and select Properties

Go to the Permissions tab

Tick the box next to Execute - "Allow executing file as a program"

And that's it! When you come out of suspend there'll be a pop up for "Volume Control" has quit unexpectedly. Just click on Reload. Also any programs that use ALSA (I guess? I'm not exactly sure, but Skype isn't affected) will crash - eg. Banshee won't work and will die shortly after I press play. Just restart those programs and everything should be sweet!

Good luck, I hope it works for you.

Hello all,

I have the same problem as listed above: No sound after hibernate/suspend. However, in my case NONE of the above solutions has worked. In order to get my sound back I have ALWAYS had to reboot my machine.

I am running Alsa on a Dell Dimension 4600 with Ubuntu Hardy (8.04). I have an M-Audio Delta 44 sound card I am using with Envy 24 control.

I find it kind of stupid that Ubuntu shuts off the audio, but yet can't remember to turn it back on in the first place. It is a rather annoying problem. Is there a way to prevent Ubuntu from shutting of the audio during suspend in the first place?

Thanx,

Geo
