Unfortunately, changing to the OSS "nv" driver doesn't have any observable effect on Jack's behavior.... I'll try futzing around with that possibility some more though... maybe VESA drivers? ick. Thanks! On 6/17/06, Jack O'Quin <jack.oquin@xxxxxxxxx> wrote:

It would not surprise me for the proprietary drivers to behave in a non-realtime-safe manner. This would affect JACK much worse than some heavily-buffered ALSA application. Can you try it with the open source driver to compare? -- joq
