[linux-audio-user] jack xruns on SUSE 9.3 with Edirol UA25 card

Hi, I'm going crazy!!! Last night, after some months playing with Ubuntu, I installed SUSE 9.3 on my amd64 with an Edirol UA-25. I installed the kernel source, patched it with rt-lsm.patch, built the modules, installed ect. Added: /sbin/modprobe -r capability /sbin/modprobe realtime any=1 mlock=1 to /etc/init.d/boot.local At this point i got a lot of xruns even with jackd -R -dalsa -p1024 -n4. On Ubuntu I worked flawlessly with -p256 -3 (17ms). I recompiled jack from source (configured with /dev/shm as temp dir) and got the same results. Then I tried to shutdown some more services that were still on (firewall and so on). I restarted jack (via qjackctl) and the xruns were gone. I've pushed jack settings until I was able to play Zynaddsubfx on my midi keyboard (Edirol PCR30 - on a different usb port), thru Muse with some plugins applied to the input channel at: -p128 -n3 (8,7ms), with no xruns and no audio glitches. -p64 -n4 (5ms), still with no xruns but with some minimum gliches. I was so happy that I thought about letting my box run forever, without shutting it down anymore. But then I decided to install the drivers for the nvidia card (the newest from their site). I don't remember if I installed or updated some rpms at the same time. Rebooted. Since then I can't get rid of xruns and audio glitches even with a 1024 buffer. After some googlin I found some old posts on this list about conflicts with the nvidia driver so I tried to restart without it. Nothing changed. Please, help me. Because I will not go to sleep until I'll solve this. Cesare
