After I Close the WMMixer application, the command

sudo ecasound -r -a:1 -i Emborian.mp3 \
-a:2 -i /dev/dsp -a:1 -o loop,1 \
-a:3,4 -i loop,1 -a:3,2 -o Emborian_Futty.wav \
-a:4 -o /dev/dsp

works now but in the mixed Emborian_Futty.wav there my sough be
overdue from Emborian.mp3.

The real time -r option don't works, right?

uname -a
... 2.6.24-etchnhalf.1-686 #1 SMP

Maybe my linux-image can't to deal with realtime work?
