There are quite a few different kernels available in the default
repositories. There is only the one that is specifically for audio
production. Ideally, all hardware specifications would be open, and we can
either build/compile our own kernels specifically for the hardware we have,
or the hardware creators would just provide, and maintain a kernel for us.
I don't make my own, but I test many that are pre made. I find the
lowlatency or even the stock generic typically meets my needs.
