I'm currently testing rt performance with (( 2.6.39 SMP PREEMPT )) Compiled with tickless timer, config-hz 1000, hr-timer, low-latency preemtion. Crackling sound, here too ! But with a PCI card. Maybe it's due to the rtirq script, which doesn't seem to work as expected with .39 ? Maybe I selected any incompatible options ? What is the KMS option ? According to jack, it's running in real-time mode. I'm waiting for a working .config now. -- E.R. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
