Comment 36 for bug 1966066

Funnily I don't have the issue with "Focusrite-Novation Scarlett 2i4", but I have:
- a regular popping with a "KORG, Inc. ToneLabST" (lsusb, product name is Vox ToneLab ST) at a tempo of around 80-90 bpm
- and a slight distortion in irregular intervals / at audio peaks with a "Harman Soundcraft 2-channel Audio Driver" (lsusb, product name is Soundcraft Signature 10)

Behaves the same on both 5.13.0-37-generic and 5.13.0-39-generic (#44-Ubuntu SMP Thu Mar 24 15:35:05 UTC 2022).

Workaround to change default-sample-rate to 48000 in /etc/pulse/daemon.conf didn't help with either kernel, tried several times. I didn't try rolling back to 5.13.0-35 yet, as I don't have it installed anymore. So I'll boot to 5.13.0-39 again and will try out the patched kernel https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.13/+bug/1966066/comments/22

As I understood, it will fix the bug introduced in 5.13.0-37 as documented here: https://github.com/torvalds/linux/commit/23939115be181bc5dbc33aa8471adcdbffa28910
