Hey,

I have this sound card and with the latest update (1.2.13), pulseaudio started to SIGSEGV and I have no sound.

Upon going to the pulseaudio IRC channel and talking to the devs, we've managed to point out that it's the UCM configuration that makes pulseaudio crash. Reverting to 1.2.12 made the crash cease.

It seems that the newly added configuration for the Ultralite makes pulseaudio crash. According to the below gdb traces, it seems the configuration drives pulseaudio into an infinite loop.

Beginning of the trace:

Debuginfod has been enabled.
To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Show ouput from alsaucm -c 0 dump text where zero is the proper ALSA card number (you can obtain card list using aplay -l command).

Hey,

Upon running alsaucm -c 2 dump text. I get this:

ALSA lib parser.c:244:(error_node) UCM is not supported for this USB device (MOTU UltraLite-mk5 at usb-0000:07:00.1-1.1, high speed @ USB07fd:000c)

Ah, this was while having the downgraded package. Using 1.2.13 has this output:

It looks fine. You should work with pulseaudio developers to fix their code.

I'm experiencing the exact same issue with my MOTU 828 (2024 version). It seems like PulseAudio no longer handles certain configurations well, even though it used to work fine. Version 1.2.13 makes it crash with a segmentation fault, but reverting to 1.2.12 resolves the problem. I'm on Manjaro Linux. Interestingly, I can still run alsaucm -c 2 dump text with version 1.2.13 installed.

Here is the dump if this can help (1.2.13):
