I also think this problem is very serious. Quite frustrating. I did not suspect that I would have such problems on the LTS version where everything should be stable. This is the third kernel update which has not fixed this problem. I keep going back to kernel 5.13.0-35.

It's because this patch introduced the available frame size check, but the conversion forgot to initialize the temporary variable properly. A workaround is to modify /etc/pulse/daemon.conf, set the default-sample-rate to 48000, uncomment it by removing the semicolon at the beginning of the line. And restart pulseaudio with: systemctl --user restart pulseaudio.service [Fix] * 23939115 ALSA: usb-audio: Fix packet size calculation regression This patch can be cherry-picked into Impish kernel, and it's already in the master-next branch of Jammy tree. [Test] Test kernels built with 5.13.0-37 + this patch, can be found in: * Focal-5.13 - https://people.canonical.com/~phlin/kernel/lp-1966066-usb-audio/focal/ * Impish-5.13 - https://people.canonical.com/~phlin/kernel/lp-1966066-usb-audio/impish/ Both kernels were tested by affected users and they're working as expected. [Where problems could occur] If this patch is incorrect, it might affect USB audio devices. [Original Bug Report] The sound card is a Focusrite Scarlett 2i2. The sound is distorted everywhere. Sound via HDMI works.
