The other thing that changed in this area between 19.04 and 19.10 was the kernel, so we need to rule that out first before pursuing PulseAudio. Please try installing kernel 5.0.0 which is more like what was in Ubuntu 19.04:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.0/ Then run 'uname -a' to confirm the older kernel is active. Does the bug still occur there? ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1858200 Title: pulseaudio produces garbage on HDMI after 19.10 Status in pulseaudio package in Ubuntu: Incomplete Bug description: After upgrading from 19.04 to 19.10, the sound output to HDMI is garbage. The sound is great on local output, on bluetooth headphones, etc. But when outputting to a HDMI TV it is garbage. I tried different users with the same problem. If I boot on Windows, the output is fine, which discards any physical problem, cables and TV as the source of the problem. I did delete any user pulseaudio configuration (and tried as a different one). I purged all system wide configuration and reinstalled the default pulseaudio configs with: apt-get -o DPkg::options::=--force-confmiss --reinstall install pulseaudio On 19.04 and before this problem did not happen at all.
