MOTU Ultralite Mk4 randomly shifts assigned channels.

Post by moreissuesthanvogue »

Brand new Ultralite Mk 4 (Windows 10, latest Mk4 driver installed). After about a minute or so the channels get rerouted (analog out 1 ends up in 6 or main right or whatever, main outs end up in channels 4,5 or whatever. This happens regardless of ASIO / ASIO4ALL / WASAPI drivers.

Here's a video I did about the issue (random rerouting happens at 1:00 mark)

I'm truly at a loss here since there doesn't seem to be much out there about this issue. I would appreciate some help debugging this because it makes my awesome interface useless.

Guys,
I am having literally the same problem. Can't even play a Youtube video even for 10 seconds straight. My DAW has become useless. Only thing that temporary fixes it is changing the buffer size but after a few seconds audio is stopped again or we get those random channel switching. How can we handle this? I have a legit installation of windows and need to keep it up-to-date
