You're going to give the single men on the list a heart attack by saying
such things. ∗haha∗

The output amplifiers? Volume settings?

Sounds like the battery would be a good start. A dead one often gives
random patches. (this _can_ be good, I've thought about a mod for my
OSCar to do the same - it can create the most outworldly effects.)

I'd start with the software. Learn to programmed a lame sound with
maximum volume before you keep searching for problems that might not
even be problems. That is what I'd do...
