Sound problems

I posted this to the community ibook, but I thought I'd post it here too in case anyone on my f-list has insight. n.n;

Hey, there is a question that has been bothering me for a while now. I bought a 12" iBook back in the spring of 2006. It is running Tiger v 10.4.11, has 1.33 GHz PowerPC G4, 1 GB DDR SDRAM. I update it frequently. I don't have S.M.A.R.T., but I do run disk utility and things are good according to that. I also use MacJanitor to clean it up from time to time. Since about mid-winter I've been using a chillmat.

My problem however started about a year or so ago. Every now and then the computer's sound cuts out. The first time it happened the sound stayed off (with volume at max and not on mute) for a few days. Then it came back. It doesn't happen super frequently, and now usually I can get it to come back by playing with the volume. I was listening to iTunes earlier today and the sound was ranging from soft to normal without actually cutting out completely. Is this something ominous?

Also, recently I have been unable to wake my computer from sleep by touching the trackpad, I have to press a button. I don't think that I changed a preference, but I might have I suppose.

Day off

Today I'm taking the day off so that I can work tomorrow. It means I don't get days off in a row this weekend, but that is ok. I would have just gone in, but I know I need the rest.

It's raining. The other interns are at work.

Yay weekend. ...I'm climbing walls. xP

It doesn't help that I'm trying to figure out what I'm going to be doing this winter. Or am I climbing walls because I'm job searching? I do have some things in the works, but nothing is guaranteed by any means. I need to keep looking.
