Hello,
I would like to report that the same regression also affects my MOTU
M2 USB audio interface on Debian 13 stable.
My MOTU M2 works correctly with kernel:
*
6.12.111+deb13-amd64
But audio playback fails with:
*
6.12.115+deb13.1-amd64
The issue persists when using a different USB port.
The device is detected correctly by USB and ALSA:
*
USB ID: 07fd:000b
*
ALSA identifies the device as M2 USB-Audio.
With PipeWire stopped, running:
speaker-test -D hw:3,0 -c 2 -r 48000 -F S32_LE -t sine -f 440 -l 5
fails with:
Write error: -5, Input/output error
No sound is produced and the interface's level meters show no
activity.
Booting again with kernel 6.12.111 restores normal audio playback.
This suggests that the regression also affects the MOTU M2, not only
the M4.
Thank you.
