I have a C400 too. I have a very poor performance on any kernel above the 5.10(XanMod, Liquorix, TkG, Canonical/Ubuntu), if I use JACK with soft mode enabled, a distorted sound occurs in randomly times when I play my guitar, even without any plugins processing the signal, without soft mode, periodic xruns occur, it's unusable to work with music production this way. On 2 different machines, it's happening the same behavior: i7 7500U, 8gb RAM and NVIDIA 940MX (IdeaPad-320) Ryzen 3500U, 8gb and Vega 8 (IdeaPad-S145) I don't know what's changed on the latest version of kernel, but I appreciate if anyone can help. I've already find a solution... https://github.com/rauldipeas/linux-rdx/blob/main/99-m-audio_fast_track_c400-c600.patch (In reply to Raul Dipeas from comment #2) > I've already find a solution... > https://github.com/rauldipeas/linux-rdx/blob/main/99-m-audio_fast_track_c400- > c600.patch It's 404. Was just some simple addition to the quirk table? If yes, at best, please submit the patch by yourself. Or at least upload the fix to Bugzilla, so that it won't be lost again.

Feel free to reopen if the problem still not fixed by the change. Thanks.
