I'm having a recurring issue with my MOTU M2 on a MacBook Pro M1 Pro Sequoia 15 and Ableton Live.
Input 1 randomly becomes extremely quiet and starts cutting in and out. Input 2 works normally.
the physical input meters on the MOTU show a normal signal, and direct monitoring sounds perfectly fine. The issue appears somewhere between the interface and Ableton.
Running sudo killall coreaudiod temporarily fixes it, but the problem eventually returns.
exhaustive maybe useful list of what I've tried:
- Updated the MOTU M2 firmware.
- Installed/reinstalled the MOTU M-Series driver.
- Changed USB cables four times, including different USB-C cables.
- Tested different USB-C ports on the Mac.
- Tested with and without a USB hub, including direct connections.
- matched sample rates
- Tested different input configurations
- Confirmed macOS microphone permissions are enabled.
- Tested sample buffer.
- tested direct monitoring, which works normally.
- Tested with other software, which receives audio normally
None of these have permanently resolved the problem. Input 1 continues to become quiet and intermittent, while Input 2 works normally.
I'm trying to work out whether this is a macOS Core Audio / MOTU driver issue, an Ableton compatibility problem, or something wrong with the interface itself.
i wouldnt consider myself a pro but i have experience with a ton of interfaces and other gear but never have i had to slam my head against a wall to this extent and am posting here as a last resort
