Re: Acer Aspire One 722 - Sound not working.

You must have tried to remove adobe flash plugin. There is a problem with that.
To correct that:

sudo mv /var/lib/dpkg/info/adobe-flashplugin.prerm /var/lib/dpkg/info/adobe-flashplugin.prerm-DISABLED
sudo apt-get remove abobe-flashplugin
sudo apt-get purge abobe-flashplugin

Then you should be able to unstall alsa-utils

Re: Acer Aspire One 722 - Sound not working.

I'm running Arch Linux 64 with the 3.0 kernel and have sound working without issue.

You can view this thread to help you out:

This link also helped out: https://bugs.launchpad.net/ubuntu/+sour … mments=all

Along with that, my headphone jack works, sensing does not, and the internal microphone works perfectly with Skype too.

No issues with Youtube either.

Re: Acer Aspire One 722 - Sound not working.

Hi there

Is there anyone who were able to fix this issue? I own an acer 522 and can't get it to work. In the crunchbang forum are two posts concerning this, but it seems that there is no solution until now. I tried other sources for debian/ubuntu systems, nothing worked (I'm not to deep in these things, since before I could solve most problems following postings).

Would be really nice to find a solution, cause I like crunchbang a lot for ocer one year.

This for example I get when I tried to open mocp:

mocp 
Running the server...
Trying JACK...
Trying ALSA...
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
Trying OSS...

FATAL_ERROR: No valid sound driver


FATAL_ERROR: Server exited

Edit: On

http://wiki.debian.org/InstallingDebian … ireOne_722

workarounds for this and other Issues is described.

Re: Acer Aspire One 722 - Sound not working.

Since this is one of the first threads that come up in a search about this issue, I thought that I would add information about steps I took to make sound and volumeicon work in Crunchbang.

The problem is that the sound for the Acer Aspire One 722 shows up as two sound cards in Alsa, and it tries to use the first one to produce sound when the second one is the one that actually works.  So you can go into the file /usr/share/alsa/alsa.conf and change all instances of:

card 0

to

card 1

The same problem is at the root of volumeicon not working.  You can open up ~/.config/volumeicon/volumeicon and add:

[Alsa]
card=hw:1

at the end of the file to make it work as well (of course this has to be done for each user).
