Title: audio crackling on usb sound card Status in linux package in Ubuntu: Confirmed Bug description: After the regular updates (on 20.04 and 21.10) audio had crackling noise on the USB audio interface, while it was normal on the internal audio. Tried with different sound cards (presonus audiobox, behringer xenyx q802) and three different machines. Might be in the kernel 5.13.0-37 Reverting to that kernel removed the problem: linux-image-5.13.0-35-generic --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: janina 1338 F.... pulseaudio /dev/snd/controlC2: janina 1338 F.... pulseaudio /dev/snd/controlC1: janina 1338 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2022-03-03 (25 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) IwConfig: lo no wireless extensions. eno1 no wireless extensions.
