ALSA settings being lost / not saved after reboot

also applies to xfce4-mixer

I found xfce4-mixer and ALSA settings were not being saved after rebooting in Jaunty Jackalope.

My solution was to first change the permission on the file that stores the settings:

This step is not vital but was handy to stop me having to sudo each time I ran alsactl or xfce4-mixer.

I set the mixer levels using: alsamixer
Then saved the settings used: alsactl store
