https://bugzilla.kernel.org/show_bug.cgi?id=212955 --- Comment #10 from Lucas Endres (jaffa225man@xxxxxxxxx) --- Thanks for your thoughts! I helped to test a change on snd-ua101 to fix its MIDI port not being created, but think it just blacklists the UA-101 from the snd-usb-audio driver, since it was conflicting. Here's a link to that discussion: https://bugzilla.kernel.org/show_bug.cgi?id=212477 Also, there have been substantial quality Roland/EDIROL/BOSS detection quirk tweaks to snd-usb-audio (also with my championing and testing), but if I understand correctly, they shouldn't be affecting the UA-101, due to its use of only snd-ua101: https://bugzilla.kernel.org/show_bug.cgi?id=212519 Sorry I hadn't mentioned these before, but until now I thought they could have nothing to do with this issue. In the next few days I hope to have time to attempt bisection to get to the bottom of it all. -- You may reply to this email to add a comment.
