So it might be worth a try if you get sound problems with any other programs.

After attempting to run alsactl store I got:

$ alsactl store
alsactl: save_state:1530: Cannot open /var/lib/alsa/asound.state for writing: Permission denied
$ sudo alsactl store
E: core-util.c: Home directory /home/mycurrentuser not ours.

So I deciced to change “/var/lib/alsa/asound.state” ownership temporarily to the current user and then was able to successfully save my sound settings (then switched back ownership to root). I also added “alsactl restore” to /etc/rc.local to automatically reload my sound settings when I reboot.

Start a terminal and use these commands (/dev/sda2 might need to be changed to match your configuration, you can use fdisk to figure out which partition is your main one):

sudo mkdir /media/karmic
sudo mount /dev/sda2 /media/karmic
sudo mount -o bind /proc /media/karmic/proc
sudo mount -o bind /dev /media/karmic/dev/
sudo cp /etc/resolv.conf /media/karmic/etc/resolv.conf
sudo chroot /media/karmic apt-get update
sudo chroot /media/karmic apt-get upgrade
sudo chroot /media/karmic apt-get dist-upgrade

  1. Install pavucontrol if it’s not already installed
  2. Start pavucontrol
  3. Play a sound in the application where you need to change the default sound device.
  4. While the sound is playing, switch back to pavucontrol and change the sound device.
  5. that should be it.

I needed to set my Logitech Clearchat Wireless Headphones as the default sound device for Skype 2.1.0.47 beta in Ubuntu Karmic Alpha (pavucontrol was not installed).

  1. Add your module to /etc/modules

    # /etc/modules: kernel modules to load at boot time.
    #
    # This file contains the names of kernel modules
    # that should be loaded at boot time, one per line.
    # Lines beginning with "#" are ignored.
    saa7134

  2. Add options saa7134 card=42 to the end of /etc/modprobe.d/options

    # Enable double-buffering so gstreamer et. al. work
    options quickcam compatible=2
    # Default hostap to managed mode
    options hostap_pci iw_mode=2
    options hostap_cs iw_mode=2
    # Stop auto-association.
    # LP: #264104
    options ipw2200 associate=0
    # XXX: Ignore HPA by default. Needs to be revisted in jaunty
    options libata ignore_hpa=1
    options saa7134 card=42

Now reboot and you should be all set.
