I was recently helping a friend who has an older machine and having problems with xruns.
I turned off his networking ( which I knew about) but also found that when ardour saves it caused an xrun, which was a new one, so I disabled autosave. These fixed the problem.
I am interested if people have found anything else that can cause xruns, having found one new to me. This thread could also end up as a useful checklist.

Re: Things that cause xruns
Rather than disabling networking (which can be a bit inconvenient), I've found that disabling NetworkManager's periodic scanning for networks with is just as effective.
Code: Select all
sudo killall -STOP NetworkManager

Re: Things that cause xruns
I'd say, just about anything that takes up any priority CPU. Personally, I just kind of "feel out" which apps I can run and which I prefer not to. Things like an oscilloscope (even a synth's own oscilloscope) can cause a lot of disturbance.

Re: Things that cause xruns
never had any troubles with ethernet networking.
only wifi, which is the official champion.
and just my 8½ cents.
in general, modern desktop-oriented distros are not good for realtime audio. by default they have too much obscure things running in the background.

Re: Things that cause xruns
I have had issues with ACPI and power management interrupts too, causing xruns. It can be a bit of trial and error to figure out what causes it.

Re: Things that cause xruns
Regarding the networking: If you want something faster (by faster I mean faster as a client to connect to a wired or wireless network via dhcp and lighter on system resources), try Intel's Connman: https://01.org/connman
There's also a nice GUI called CMST: https://github.com/andrew-bibb/cmst
Unfortunately Network Manager seems to be a hard dependency for most desktop environments, so your mileage may vary, but I'd speculate it is still a dog performance wise (it used to be perfectly horrible, although things seems to have improved a bit).
At least with Connman, I don't remember having to turn wifi off because of xruns in recent history...

Re: Things that cause xruns
On my DAW I'm running debian testing with no 'live' network monitoring at all. I never use it for browsing other other 'social' operations, and if I actually want to do an upgrade (very rare) it's no real hassle to plug in the network and do a reboot.
