The fifo error also occur when using the pause/resume button of xmms 
1.2.10 (alsa 1.2.10 output plugin) to pause and resume of the playing of 
music.

vortex: start 0
vortex: IRQ fifo error
vortex: pause 0
vortex: resume 0
vortex: IRQ fifo error
vortex: pause 0
vortex: resume 0
vortex: pause 0
vortex: resume 0
vortex: IRQ fifo error
vortex: pause 0
vortex: resume 0
vortex: IRQ fifo error
vortex: stop 0


1) How to prove that it is just a harmless "fifo empty" error ?

The outls.wav and outrs.wav (may be too short) cannot be paused in xmms.
