As mentioned above, I tried uninstalling all GA packages and I still saw the "Version 6.0.0" line in the log until I explicitly blacklisted the vboxguest module that ships with the kernel. Perhaps additional work is required under Manjaro to ensure the vboxguest module from the GA package ...

I did so previously, but tried again now with the reinstalled guest additions.

Using 1 vCPU the problem still occurs (VBox.log attached).

I removed the guest additions, but saw that the vboxguest module was still loaded after rebooting. Looking further, it seems that this module is included in the upstream Linux 5.10 kernel, and indeed reports version 6.0.0: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drive...

This is a desktop system without built-in speakers, but I do have it connected to a TV via HDMI and can confirm that the problem happens identically with the audio that comes out the TV. (I've rebooted many times since the problem started happening a few months ago, so I'm confident it's not transie...

I remembered that I also switched from using USB headphones (which would have their own DAC) to analog headphones last summer, so it's possible that was when it started and upgrading VirtualBox was not the cause.

Just tried it, the problem still occurs with the same frequency using 4 CPUs with both Manjaro and Ubuntu.

During normal usage of my guest VM, I hear frequent pops in my _host_ audio, regardless of source (streaming music, playing local file, browser audio). It is correlated with graphical changes in the guest: the easiest way to trigger it is to scroll a window in the guest, and when the guest is not vi...
