My USB device outputs popping noise on the 44100Hz sample rate with JACK in 5.13.0-37. This seems to be similar issue on this bug.
Related Discussion: https://askubuntu.com/questions/1399136/sound-not-working-on-ubuntu-20-04 In my case, downgrading to 5.13.0-35 fixed this issue. cd ~/Desktop git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/focal cd focal git checkout -b hwe-5.13 origin/hwe-5.13 git checkout -b hwe-5.13-next origin/hwe-5.13-next git diff hwe-5.13 hwe-5.13-next sound/usb/* --name-only Several advanced differences via rebase. Note hwe-5.13 has been still on 5.13.0-35. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1966066 Title: audio from external sound card is distorted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1966066/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
