Folks who want low latency audio may find this interesting!

Yeah! Stress levels have been high lately. I hope all is good on your side!

@indy , that kernel version should also do the job for you ;

### linux-cachyos-rt-bore

The RT (realtime) kernel contains the CachyOS Base Patchset, Real Time Patch and BORE Scheduler. RT Preemption enabled by default.

Edit: Unless that you already tried it.

Yes! I tried it and thought the ‘Link Time Optimization’ version was better.

❯ uname -a
Linux mlrig 6.11.5-2-cachyos-rt-bore-lto #1 SMP PREEMPT Fri, 25 Oct 2024 23:15:30 +0000 x86_64 GNU/Linux

Hey cool, lots of testing on your side @indy

Edit: Just saw these links about LTO;

While playing around with DAWs on Windows and Mac, I became curious about Linux DAWs. Recent improvements in Pipewire and realising how easy it is to set up Bitwig Studio in Linux have made me use Linux for audio. 256 block size with a stable OS is great. Cachy OS with RT BORE LTO kernel is better than Ubuntu Studio.

LTO articles are very interesting. Thank for the links.

Cool, it s good to know about DAWs & Linux that can work properly , it was some mess some years ago.

You re welcomed @indy , had the time, & had some interests also.

I also noticed that this kernel runs at a 1000Hz tick rate!
Extracted from the /proc/config.gz

CONFIG_HZ_1000=y
CONFIG_HZ=1000

Great, saw some tweakings years ago ina forum that was talkin about Tick Rate, it s also interesting as well, but can be overhelming at times ! lol

Hey @ptr1337, a little birdy told me:

On CachyOS, the string “-rt-” in their kernel names does not mean the kernel is configured with PREEMPT_RT=y . I installed both CachyOS RT kernels and they were built with PREEMPT_AUTO , not PREEMPT_RT.

Does it make sense to compile the linux-cachyos-rt-bore-lto kernel with the PREEMPT_RT=y ?
