So that does substantially help matters -- I have to try pretty hard to
make it skip in that situation. It unfortunately also chews through
battery life and makes the fan scream like some kind of gently blowing
banshee. Needing 1.7GHz of processing power to download email and play
music seems a bit overkill.
But ok, it may be *switching* performance levels that is the problem
(since that will occur when my mail client wakes up and does stuff). If
that is the case, what kind of things could I do? I've previously tried
re-nicing rhythmbox and esd to -19 and it seemed to have no measurable
effect.
