I've tested audacious this morning too, but it is even worse than xmms
regarding this issue. When both are idle this is what I get:

Top causes for wakeups:
   34.7% (136.8)         audacious : schedule_timeout (process_timeout)
   23.7% ( 93.3)              xmms : schedule_timeout (process_timeout)

I have also tried to take a look at xmms code, and I found out that
one of the major causes of wakeups is this line in main.c:

mainwin_timeout_tag = gtk_timeout_add(10, idle_func, NULL);

If I increase the number 10, I get less wakeups. If I comment the whole
line the number of wakeups decrease a lot (I get 10 instead of 93).

However, I don't know the effect of changing this value, because to
make the vanilla xmms 1.2.10 compile with gcc-4.2.1 I had to change
some things (I removed two lines from General/ir/ir.h). Xmms then
compiles fine, but is unable to load and play songs. Modifying the
source code further to decrease the wakeups, I get the same behaviour
(does not play).
