Just for reference, I'm running the stock Debian Bookworm kernel (non-RT, non-low-latency) using a USB audio card, and it's providing 10.7ms latency. That was true on my old laptop (Intel i9, 64GB RAM) and my new desktop (Ryzen 9950X, 128GB RAM). Both were configured for on-demand, using JACK, with PulseAudio feeding into JACK.> #2. Generic Kernel is useless for Audio.
install lowlatency kernel &/or liquorix kernel.
This is no longer true. Generic kernels contain more or less the entire RT-PREEMPTION patch set these days, and will function at least well as the so-called low-latency kernel. If you want to do better, you need the "RT" kernel provided by your distro, not the "low latency" one.
