Public bug reported:
Recently I'm having an issue where the audio playback from my HDMI
output starts crackling at random intervals in Ubuntu 22.04. 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.
