External sound-card UR22C no longer works with newer linux kernels (5.13.X)

[cs]

Hi,

I own a Steinberg UR22C external soundcard and was a very happy linux user, until suddenly it stopped to work with newer linux kernel versions.

I'm on kernel 5.13 now and pulseaudio or pipewire regularily crash whenever I plug in the sound card's USB cable.

I get error messages like this:

[ 205.104301] pulseaudio[13215]: segfault at 50 ip 0000000000000050 sp 00007fff7b003078 error 14 in pulseaudio[55ac78ff4000+5000]
[ 205.104313] Code: Unable to access opcode bytes at RIP 0x26.

I've installed the newest Steinberg firmware for the UR22C with no avail.

This did never happen with older kernels (5.12.X)

Is it a known issue? Is there a workaround or fix?

Regards

Is it a known issue?

Than only can answer, who has such soundcard.

Is there a workaround or fix?

Hard to say, have you googled about it?

@towo:
Yes, I've googled with no avail. I've now posted in the Steinberg forum: Perhaps there are people with similar problems.

By the way: A hearty thank you for your endless efforts to provide us with the latest kernels!

:-)

Linux 5.13.6 will get many alsa and usb fixes, maybe it helps for your problem.

@towo:
Looking forward for kernel 5.13.6 then!
