First of all, I'd just like to celebrate that this is the first post I've been able to type from this laptop!
Second, I'm having a slight problem with sound. I'm not too familiar with how sound works under Linux, but I know I had to run alsaconfig to set everything up. Now, even though my alsamixer settings never change and are all at the correct levels, I don't get any sound from the machine. The only way I've found to get it to work is to go into kmix, move the two sliders on the left up (they're initially at zero), and then play the sound. This works for the session, but everything is back to zero again after I reboot, even if I choose the "Set as default configuration" option in kmix. Why is this happening, and how can I fix it?
