Hi,
You appear to be running into a known issue with running FMOD on Linux systems with reduced audio services, which has already been passed on to the development team for further investigation. Another user who ran into the has posted a workaround here: Getting PulseAudio dependency to work in Ubuntu Docker image - #2 by joeanderson
As well as a GitHub repo demonstrating the error and the workaround: Getting PulseAudio dependency to work in Ubuntu Docker image - #4 by joeanderson
I would recommend giving that user’s workaround a try and seeing whether it resolves the issue for you.
