Dear Maintainer,
I am experiencing the same regression on Debian Trixie with
a different device model from the MOTU M-Series:
MOTU M2, hardware revision: 1, firmware version: 1.02 (latest).
- Working kernel version: 6.12.113+deb13-amd64
- Broken kernel version: 6.12.115+deb13.1-amd64
the M2 is recognized on the USB level, but as soon as audio streaming is
initiated, the driver deadlocks. In my case, running
jackd -dalsa -dhw:1 -r48000 -p256 -n3
and then starting audacity results in a 5-second timeout:
JackPosixProcessSync::LockedTimedWait error usec = 5000000 err = Connection
timed out
Driver is not running
Cannot create new client
Pipewire and pulseaudio were disabled. Testing with a smaller or larger
buffer size (-p 64 or -p 1024, respectively) does not change the
behavior. Booting back into 6.12.113 fixes the problem immediately.
CPU: Intel Core Ultra 7 255U
USB controller: Intel Corporation Arrow Lake USB 3.2 xHCI Controller
thanks,
Sebastian
