Are you letting ardour start jack or are you using something else? In any case you will need jack to run at 128frames/period or less. (probably 64) Ardour starts jack at 1024 by default if I remember correctly... so does qjackctl for that matter. > 1) At Arodur3 install time there was some option about monitoring and > I've chosen 'something' which could have been the default.

Off is preferred because that means you are taking care of monitoring in hardware :) On means Ardour sets up monitoring channels, but in this case you are doing that manually anyway. > 2) Is this now a direct consequence of not using any low-latency > kernel ? Direct no. The kernel will determine the lowest usable latency you can use, but the way jack is started determines what latency jack is (trying to be) using. If you can't get jack to run at the needed latency without xruns then a change in kernel may help. Other settings in bios and HW wise may help too. Finally, there is a matter of processing power. The more effects you use the higher the latency needs to be to support them. I have an older machine and so I try to track without internal eq/effects. I add effects for mixdown at a higher latency. I do have an external mixer (Mackie 1604) and some external reverbs and stuff I can use for monitoring, but I have been tracking dry so far. Effects for tracking monitoring do not have to be super quality, just good enough to keep the talent in the right frame of mind. Some talent needs it and some don't. > > Thanks for any comments/suggestions - much appreciated as always. > > Cheers. > > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user@xxxxxxxxxxxxxxxxxxxx > http://lists.linuxaudio.org/listinfo/linux-audio-user > -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
