@rockpilp - and for anyone else watching / looking - I’ve put together a docker container and instructions how to get the pi PlexAmp working on Ubuntu 20.04 for amd64. It should definitely be do-able for other distributions as well with minimal changes required. The instructions are on gitlab here: Ed McLain / PlexAmp Headless x64 · GitLab
Let me know if you have any questions and/or if it works for you!
