-lowlatency kernels aren't from KXStudio, it is in the official Ubuntu repositories, and we include it in our live images. Andy Whitcroft of Canonical is the main maintainer of the -lowlatency kernels, though I think our kernel team (mainly zequence) wants to maintain the precise kernels.
-rt kernels are from the KXStudio repos. However I use -lowlatency kernel 3.5.0.17, and it works great. smartboyhw On Nov 3, 2012 8:44 AM, "ttoine" <[email protected]> wrote: > I am running 3.5.0.17 -lowlatency, I think from KXstudio repositories. > Works great with Ubuntu 12.10. > > > 2012/11/3 Kaj Ailomaa <[email protected]> > >> On Fri, 02 Nov 2012 23:58:39 +0100, Ralf Mardorf < >> [email protected]> wrote: >> >> Hi :) >>> >>> on Ubuntu Studio Quantal I switched to >>> $ uname -a >>> Linux qrc 3.6.5-rt14 #1 SMP PREEMPT RT Fri Nov 2 21:36:37 CET 2012 >>> x86_64 x86_64 x86_64 GNU/Linux >>> >>> A kernel-rt seems to be much better on my machine. >>> >>> With the kernel-lowlatency for a very small audio session, CPU usage >>> "< 10%", I get xruns with >>> >>> sample_rate=48000 >>> frames_period=512 >>> >>> Now, with the kernel-rt everything seems to be [Ok] with >>> >>> frames_period=256 >>> >>> but with frames_period=128 I get xruns again. >>> >>> Regards, >>> Ralf >>> >>> >> Did you compare with a lowlatency of the same kernel version? >> If not, the test is not very conclusive. >> >> If you like to see some good results from a lowlatency kernel, try >> 2.6.37, and perhaps also 2.6.38 and 2.6.39 >> As you might have experienced, something made kernels less reliable from >> somewhere around version 3. >> I haven't tried 3.6 series yet. >> >> >> -- >> Ubuntu-Studio-devel mailing list >> Ubuntu-Studio-devel@lists.**ubuntu.com<[email protected]> >> Modify settings or unsubscribe at: https://lists.ubuntu.com/** >> mailman/listinfo/ubuntu-**studio-devel<https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel> >> > > > -- > Ubuntu-Studio-devel mailing list > [email protected] > Modify settings or unsubscribe at: > https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel > >
