MOTU M2 Wasapi incompatibility

Hi!

I just started my trial with Audirvana, unfortunately I can’t use my MOTU M2 USB interface in WASAPI mode, it throws the error “Unable to change to Integer mode”.

I have read that this mode is for USB DACs, but it doesn’t work for me.

Any idea what could be wrong?
Thanks!

Have you tried to disable the integer mode?

Hello,
I also have a Motu M2, and I have the same issue.
The Motu works flawlessly in Wasapi with AIMP and other apps but not with Audirvana…

I have been discussing this issue with Audirvana support for the past weeks but they did not find a solution.

Asio works well.

Did you found a solution?
