It's been a year since I have made this bug report. I no longer use this configuration, but since there was no further activity I consider this bug to be no longer relevant and should be closed.

It is not sure if Virtualbox is causing this issue, but it's a possible cause. I dug up a forum post from 2 years ago on AskUbuntu where someone implies Virtualbox causes their issue. Since Virtualbox runs in the background all the time for me, I cannot be certain about this. I run my Home Asisstant server inside Virtualbox. If any audio playback starts crackling, executing pulseaudio -k always fixes it. Then the applications producing sound need to be restarted in order to get any sound out of them. After that the crackling will take hours to show up again. In that AskUbuntu forum post that I referred to earlier, the user fixed this by setting resample-method = speex-float-10 in /etc/pulse/daemon.conf. So I did the same thing just before filling this bug report to see if that would fix it. I do not have enough data yet to draw any conclusions. I can be sure that the crackling is from the HDMI sound output and not from malfunctioning speakers, since no other devices connected to the same speakers/TV have this issue.
