@baptiste
Can you post the changes you had to make to the patch? The patch I shared with @buonamorte.records was based off of the zen-kernel 6.0.3-zen2 which might be slightly different than the 6.0.3 vanilla code, but I would be surprised if any of the patch was already applied.
So it might be a good idea to build the zen kernel instead. I remember the second part of the patch wouldn't be applied completely because the line number didn't match. I looked for the code and found it, and IIRC, it was already applied. It's been two weeks since i did it, so i can't remember exactly. Fact is, it was applied finally anyway, i triple checked.

With the latest firmware, you should see the printk "MOTU Patch" emitted in the kernel log (dmesg) whenever an audio stream starts. Can you also confirm the presence of this log?
While the channel hop could still occur with the patch, I'm a bit surprised you ran into it so quickly, so I want to double check that the patch is truly active.
I've just reflashed the 1.40 firmware :

Am i right if i say that we are supposed to test the patch with the latest firmware version ?
Yes, the patch should work the latest firmware version.
Ok, thanks again !
