Subject: occasional under/overruns with ecasound

Hi all!
I still have occasional under/overruns with ecasound. And sometimes I get
small pops (which aren't counted). I use alsa 1.0.3 and a delta 1010lt card.
As input I use a simple alsa plug device (io1) with ttable mapping and as
output I use a plug device wrapping a dshare-device. Both devices are on the
same card. I have a 2.6.3 kernel with preemption built in. Also I use a lot of
real-time options, which I have to, because otherwise I get terrible latency.
That is irretating when playing live. Can any one give me a hint or another
idea of how to tune my setup.
Btw. The cpu is ok and so are the disks. Usually the pops also happen when I
do:
rteca -i alsa,io1 -o alsa,p1
(rteca is a small script, which contains all the buffering and
realtime=priority options. the main buffer is set to 64, priority is high and
I run ecasound as root.
Kindest regards
Julien
