If this would be the issue, then why can he start Jack1 with ... "driver: alsa RT with default priority samples/period: 128 sampling freq: 96000 period/buffer: 3 max numb of ports: 128 count-down: 500 dither: none audio: duplex input device: hw:0 output device: hw:0 late start: 2 seconds" ... ;)? Again, regarding to Jack2 there is a small chance that it's related to D-Bus and regarding to the issue, the thread is about, he needs to switch the CPU freq scaling to performance, since ondemand is asking for trouble and I suspect, that the latency is much to small. Besides it would be better to use "period/buffer: 3", assumed the card is able to do it, but the period/buffer isn't related to any of the issues, it's just better to use 2 when ever possible. If he wouldn't be in the group audio, he couldn't start Jack1 in RT mode. Regards, Ralf -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
