My volume knob is starting to have the problem many of you have had, with the volume going down sometimes when I turn it up, and visa versa. It also doesn't respond sometimes to slow increments.

I know this has been talked about quite a bit, but what is the best solution - clean it, purchase a new volume knob, or is it software related?

If I need to purchase a new one, how can I go about doing that?

Thanks guys!
