How to upgrade to low latency kernel on Pi OS(Debian bookworm) for snake oil?

Even replaced with lowlatency or even real time kernel, the clock on Pi's motherboard (oscillator) is too lousy.  And there is not hpet in Pi.  Apart from the convenience, I'm afraid that Pi can't produce very good music quality.

asynchronous usb can use DAC's deluxe oscillator instead of Pi's poor one, don't worry

There is no low latency kernel.  There may be a real time kernel coming in the next release.  

If you cannot wait, you can build one yourself following my process

Thanks! If installing Ubuntu server on Pi, can "sudo apt install linux-lowlatency" work?

Maybe you need some more time and tests to see what I mean.  Moreover, there is no hpet, not even TSC clocksource in pi.  That also significantly affects the sound quality.  Unless you've already brought the Pi, just don't buy it for cas.

Btw, you can install lowlaterncy kernel, and even real time kernel in Ubuntu server.  But after reboot, only the stock kernel is used by pi.   If you've digged a bit more in recent post (Last December), you'll find another webmate found a way to get Pi to boot with these kernels by renaming them, yet I can't make it.  And in another web it provides a ready made real-time kernel Ubuntu Server 22.04LTS.  I've used it and mentioned in the same thread, too.
