Hmm I have to check, I think i deactivated audit as well.
I haven't done any real profiling, but to be honest I don't think there's
a huge difference, no. From a purely intuitive assessment, it takes a little
more load to cause xruns.
Best,
Niklas

Hi,
for testing purpose you might want to disable audit by boot parameter
'audit=off', too. If you should use the kernel config of the AUR tarball
( https://aur.archlinux.org/packages/linux-rt/ ) , audit is
enabled.

Btw. does it make a noticeable difference for rt audio performance on
your machine, if you disable those mitigations? Did you compare the
performance with and without mitigations?

The other thing to check, as usual with USB devices, is ... every single
USB port. Sometimes a device will work very badly on one port and
completely fine on another. This is true even on Apple machines. Amazing,
but true.

That's interesting, I never noticed that.
Thomas noted earlier that it's a good idea to look for the least busiest bus,
I wonder if that's related? On the other hand, I usually don't have any other
hardware connected except the interface ...

Yes, that's the same advice basically.

You may think that, but in fact the trackpad, keyboard, fingerprint
reader etc. might internally be USB devices which are on the same bus.
You may see this with the lsusb command.
I had a look on the board schematic of my laptop and noticed that USB
actually has completely unused buses. In the hope the docking station
would expose those I got one only to be disappointed that the docking
station was just acting as another hub to one of the already accessible
buses :/ With some hardware hacking it might be possible to access the
other buses, I opened the laptop to have a look but in the end wasn't
adventurous enough to actually try it :)
