Checked 5.9.16 - the same 5.8.5 - much rare and smaller (but 'cracks' still exists).
Also there are cracks in 90% cases when i click on kmix tray app (opens kmix window), when i change volume or tab in kmix (between apps and hw), or when another app open stream. Its on all kernels and was on 20.04 too. 5.12 cant check, i have home profile on zfs, zfs dkms not builds on it. Also it much bigger in time and more noticeable now. There is no cracks when playing one stream on ae-5 and xonar d1, only usb affected. But there is sometimes when new app open stream or volume is changed, its not the case of that bug report, seems it some kind of general architecture problem >:-( >:-[ -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1930550 Title: usb sound devices crackling Status in pulseaudio package in Ubuntu: Incomplete Bug description: After upgrade from 20.04 to 21.04 all 3 my usb sound devices start crackling, i have xduoo05plus, audeze mobius, audient id4.
