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.
