Hmm, interesting.

That's the kind of problems I've got with my Focusrite 18i8.

With 5.15 (and still with 5.16.2rt19), I've got an output cracking noise while there are no Xruns reported by qjackctl.

If I boot on the 5.10.90rt kernel, there are absolutely no problems.

Where can I report this kind of problem ?

What kind of informations I can gather to help fix this problem ?

Best regards,

Yann

There is also the problem with usb devices that the latency changes every

Apparently now fixed (or certainly much better) in recent kernels.

Should be fixed in 5.16: https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?h=for-next&id=d5f871f89e21bb71827ea57bd484eedea85839a0


Best,
