Hi, I’m also working with a pi 4 8gb, and it seems like my USB ports aren’t working as well. I don’t have a pi 3 to do your workaround. Is there another way to solve this issue? Thanks!
Edit: flashing this version of patchbox and setting the jack to 48k/ 256 buffer seems to have solved my USB issues. Even at 256 the latency feels almost nonexistent, and since I’ll mostly be using it for return FX I’m not sure it’ll be noticable anyway.
