Hi, I am a musician and programmer. I use a laptop with an internal soundcard (intel) and ubuntu studo. When I see the qjack control settings window I always see a 46.6 ms latency. On a older Desktop computer with an internal ac97 soundcard or an pci sweex (cheap) I have the same problem. Reducing the sample period to 512 , reduces the latency, but always ends up with problems. My question is how to have a good studio setup for recording (and playing midi in the background)? Is it possible to better the performance with an external soundcard? What are your experiences? I also tried ccma an av linux, but the same problems. Anyone suggestions? Regards, Dave Stikkolorum

Hopefully optimizing yours system yields better performance. I'd start with setting CPU scaling to performance. Best, Jeremy
