After updating kernel to latest, my Roland audio device no longer shows up in aplay -l or cat /proc/asound/cards.
I'm running Arch Linux. The last known good kernel was 6.0.2-arch1, and I was able to determine by booting a couple of virtual machines in qemu that an upstream patch shipped in 6.0.3-arch3 refactors card registration, and effectively breaks initialization of this device.
I will be looking at this later this evening attempting to implement a fix that doesn't depend on reverting this patch, and may update this bug report with more details.
Hopefully it's the same issue that has been fixed recently. Could you try the patch?
If this doesn't work, please give alsa-info.sh output. Run the script with --no-upload option and attach the output to Bugzilla. Also, lsusb -vv output for the device, too.
I've tested this patch against 6.0.3 and 6.0.7 and they are both able to arecord -D hw:STUDIOCAPTURE -r 96000 -f S32_LE -c 18
