Whats going on here is that in the Touch are two DACs, one connected to
the RCA jacks (the "hi-fi" DAC) and one connected to the internal
speaker which produces the bleeps and blurps ect, (the "effects" DAC).
Normally there is a separate jive-alsa process just for the effects
channel, this is a rather big waste of resources and interrupts etc, so
TT2.0 disables that separate process, but that means there is no place
for the effects noises to go, so they wind up getting routed to the
main system along with the music. The problem is that the effects
noises are at a lower sample rate so when they get played on the main
channel they cause all kinds of crackling etc because they are at a
different sample rate than the music.

As has been mentioned the solution is just to turn  off all effect
sounds.
