Does the low latency kernel make any difference ?

Hii Team,

I have been experimentimg with both the normal and low latency kernel with Jamulus. Personally i cannot see any difference in the millisecond  delays. I wondered what others have found ?

Thanks, Kieran

Hello Kieran,

Indeed with the same parameters in qjackctl, there is no difference in latency between lowlatency and generic kernels but it is likely to increase the audio signal stability (e.g. less XRuns). You can see the Xruns by clicking on "Messages" button in qjackctl.

The Xruns are desynchronization and sometimes you can hear it (distortion or no sound at all when Xruns are numerous).

It's possible that you see really no differences but beware that lowlatency kernels are recommended for audio. You will see more differences when the system load increase.

BR,
Laurent
