Have been regularly applying Software Updates with varying degrees of success.
One thing I did see, once, which was interesting. The "Tick Tock" noise happened at the same time that the volume indicator started changing "quiet then loud". Theory - there are two things changing the sound volume - one quiet, one loud and the ticking noise is happening because of that. So, where does the sound system do that, then? If that can be found, the bug can be killed. -- 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.
