Python Script to run VLC media file python3-vlc

Question

Trying to open mp3 file with VLC from within Python script. It opens VLC and the mp3 but no sound. VLC proves to show a Connect Refusal Error.

Have tried with sudo and has error of running as root. Unsure how to stop the error of VLC and PULSE AUDIO CONNECTION. Do I need to start vlc using different command?

Use 'cvlc' to use vlc without interface. QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-thom'
