Dear Maintainer,

Recent upgrade changed the linux kernel on Debian stable from
linux-image-6.12.113+deb13.1-amd64
to
linux-image-6.12.115+deb13.1-amd64

When booting on this new kernel, there is no more sound output on my USB sound
card Motu M4. Despite it's still listed.

Booting back on linux-image-6.12.113+deb13.1-amd64 resolves the issue.

The problem and solution is reproducible.

I see other user reporting similar regression for this kernel but other usb
sound card Focusrite Scarlett 8i6

Here is my model from dmesg:
