I would like to optimize my laptop for creative audio usage (tracking,
running digital instruments, mixing, all what is commonly provided by
current Digital Audio Workstations (DAW)). For this I read and
understand that one important parameter of Linux optimization could be
to use a real time kernel, and to use some other more specialized audio
related components like JACK and nowadays also pipewire, and of course
configure them all correctly. Guides about the proper configuration are
published and I expect to be able to follow those guides successfully.
Concerning the required real time kernel functionality, it is commonly
commented, that current main stream kernels would actually be sufficient
for accomplishing sufficient prioritization of the audio related
communications and streams in the system, and I read that especially
kernel 6.12 would have received all wished functionality for this and
thus would be a very good choice to use.

Hello,
I do not record/produce music so take what follows with a grain of salt :-)
Linux DAWs being having been around for an already long time, even if
Linux 6.12 brings improvements to the workflow, I doubt it is mandatory
for sufficiently good results.
What seems to be efficient if you work with more than a few
instruments/tracks, is, yes, a realtime kernel
Debian standard (by default) kernel is not realtime, but Debian provides
realtime kernels in its repositories. For an AMD64 PC and Debian 12
Bookworm (without backports), the last LTS realtime kernel package is:
linux-image-6.1.0-29-rt-amd64
from backports there is:
linux-image-6.11.5+bpo-rt-amd64
It probably would be good enough, I think (If I remember correctly,
there was a thread in the debian.user.french mailing list where a
contributor said that for him Debian RT kernels are very suitable for
DAW usage and I don not think he was not using backports)
So If I would try first a realtime kernel from Bookworm without
backports :-)
