I made a little progress. I found that if I use the asoundrc from this bug (https://bugs.launchpad.net/mixxx/+bug/259566), I can use the ALSA driver with a latency of 5ms. It doesn't crash, and I don't get any dropouts. I'm guessing the overhead of having Mixxx talk through Portaudio which then talks to JACK is just a little too much to get latency down that far.
I suspect if I want to get really low latencies with jack turned on, I'd have to write a native JACK backend for mixxx that avoids portaudio. The reason I prefer JACK is I can pipe Mixxx's output to a whole bunch of jack-racks with custom effects I've created. Has anybody thought about coding a native JACK backend before, or is there a reason I shouldn't bother? Otherwise I'll take a crack at it. owen ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ Mixxx-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mixxx-devel
