TL;DR - This bug has been fixed. Detail... As of last Saturday (14th November 2020), this bug no longer happens with both Ubuntu 20.04.1 and 20.10. I also noticed that the sound was very much louder than expected from my system - reducing the volume fixed that OK. Tested sound by playing a music video in YouTube. There is the occasional crackle when booting or changing the volume but that is OK.
Ubuntu 20.04.1 Both kernels 5.4.0-53 and 5.4.0-54 were fine. Ubuntu 20.10 Kernel 5.8.0-28, also fine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1899145 Title: Getting a repeating, white-noise like "tik tok" from speakers Status in linux package in Ubuntu: Confirmed Bug description: This bug appears on 20.04 and 20.10 I believe it is a kernel bug.
