Anyone more experience with Linux have any experience using low latency kernels? I've been having lots of audio issues when my CPU gets pinned to about 30 to 50% and I'm wondering if using a low latency kernel would clear things up.
I'm also wondering if this would make audio production on Linux much more tolerable.

You try asking the folks in the www.reaperaudio.com forums? They have a beta that runs on Linux and there forum was always good for questions like that.
I have not. I didn't even know that form existed. Thank you.
I've used em before.. It was ok, I haven't tried the new pro audio.. the low latency is only really needed if you're doing record+monitor playing live instruments. I need to bench my new pipewire setup and see how many ms delay it is with realtime jams ..
Are you already doing Wayland+pipewire? It could help cause it may just be you're emulating a lot of stuff you don't need to
I just realized I had three different audio systems installed. Jackd, pulseaudio and asla. I wonder if that can be part of my problems.
I'm thinking it's time for a clean slate install. I've been using PopOS for a couple years and I've done a lot of experimenting on it. I'm wondering if just reverting back to Debian would be a good idea at this point and kind of start from scratch.
jack2 for audio
pipewire is ok but if it's about audio, jack2
as far as low latency kernels, i'm not sure, if it was 5 or 6 kernel but i feel pretty sure that in 5 they created a realtime priority option for processes and jack/jack2/etc all started using it to make sure that audio buffers (and video) were filled before any compute was done
what is more likely to cause you issues is pulseaudio or pipewire
neither of those are tuned for minimal latency, and having an aggressively preemptive kernel isn't gonna change that, if anything, more likely result in buffers not being filled before they are dumped on the audio device
Have you tried Ubuntu Studio? It uses the low latency kernel and has a lot of things already set up for audio production. You could run it from a thumb drive or spare hard drive to see if it fixes your issues without messing with your current system.
I have not. But I was just reading about it on some forums after doing a quick search.
