You don't mention your sound card/device which is probably more than
important than CPU/RAM. Whilst the glitch might make you think your
system is struggling power-wise, it's probably a driver issue. You
might want to have a look at this page to check it's not on there:

I'd also suggest running dmesg (or looking at /var/log/messages as
root) to see if anything pertinent is in there. In fact, try running -
as root - "tail -f /var/log/messages". Keep it in sight whilst you're
playing music and see if a glitch occurs, check if an error came out
in the log. Then you might want to join and send a message to the
pulseaudio list with details of the messages, your sound device, and
the stuff you mentioned in your email.

Cheers, Chris.
