This script tells you where your system can still be optimized: https://github.com/raboof/realtimeconfigquickscan
There is no need to do that. Ubuntu Studio is already optimized for realtime audio out of the box. No system administration needed.
Does this also account for networking via LAN?thetotalchaos wrote: ↑Fri Mar 20, 2020 9:32 pm Hi @Digital Larry
Ubuntu Studio (especially the recent versions) is set to optimize audio performance out of the box. You really don't need to change anything in the system. Ubuntu Studio is already set off.
In fact the way to actually boost the performance and minimize the xruns, is to stop networking, during your music sessions and to look and check off any startup modules and services, that you don't use.
Let me mention the things that you shouldn't do. Don't use external repositories. Particularly don't use KXStudio repositories for anything more than a backports repository. KXStudio handles audio slightly differently. That could lead to a mess of settings, that try to overwrite each other. I have seen it in this forum. So many people complaining, how their sound does not behave as expected. And they don't realize that they have overcooked their food.
Another thing you shouldn't do is to prefer upstream over stability. You should make a production machine as stable as possible. The only unstable thing should be you.

Yes it does. Theoretically not as much as WIFI, but more than you believe. Linux-RT and Networking really don't like each other. I remember UbuntuStudio 9.04 was one of the last version with realtime kernel by default. And when i tried to open something a little more big with Firefox, the whole system freeze. And at the same time it had one of the best audio performance, that i can remember.lilith wrote: ↑Fri Mar 20, 2020 9:43 pmDoes this also account for networking via LAN?thetotalchaos wrote: ↑Fri Mar 20, 2020 9:32 pm In fact the way to actually boost the performance and minimize the xruns, is to stop networking, during your music sessions and to look and check off any startup modules and services, that you don't use.
Ok, I will check that, maybe that's causing my xruns.thetotalchaos wrote: ↑Fri Mar 20, 2020 9:52 pmYes it does. Theoretically not as much as WIFI, but more than you believe.

Thanks very much. Indeed, I am probably unstable! The system seems to be working OK now. I haven't installed any other repos or backports but of course I did download and compile Faust from code, otherwise I would not have it!thetotalchaos wrote: ↑Fri Mar 20, 2020 9:32 pm Hi @Digital Larry

OK, I'm following this. The onboard audio sometimes gets detected as Pulse Audio but I have no intention of using it, just the USB Audio I/F. Does the advice in this article seem OK to you?
