I have not been able to use ALSA in Reaper with my interface: NI Session
I can select ALSA in Reaper on a Vanilla install of any distro, then select my interface for ins and outs but when I hit apply:
ALSA: error setting input device format bits
I tried many distros currently the best for my setup is Xubuntu and also trying on the side Manjaro-RT cinnamon.
I have no problem setting things up with Cadence and use ALSA via jack, but I get some crackles after with only 1 or 2 instruments at 256 sample 5,6ms latency. Instruments are either Repro-5 from U-he (native linux) or it could be Kontakt via Linvst.
I understand these might not be optimized for Linux but on my Win7 boot on same computer I can get up to 10 heavy instruments in realtime 3,5-5 ms no problem.
Also HTOP shows high random activity for Pulseaudio or Cinnamon --replace when real-time kernel is on for both Xubuntu and Manjaro.
I'd like to try ALSA but everything I tried so far tells me my interface maybe is not supported by ALSA ?
Pulse recognise it no problem everything works in Pulseaudio.

set realtime priorities
If they are not set then cpu spiking can occur with Kontakt and other plugins.

Manjaro-RT does'nt set realtime ? That's weird. Is it really worth it to enter these commands it seems to break the OS the more fiddle with it.
It's just editing a few files and adding a few lines.
The editor I've got by default on Manjaro is Mousepad, so the editing commands (using a terminal) would be
sudo mousepad /etc/security/limits.d/audio.conf
and so on for the other files (/etc/security/limits.conf, /etc/group).
If the entries are already in those files (/etc/security/limits.d/audio.conf, /etc/security/limits.conf, /etc/group) then obviously nothing needs to be changed in them.
