I been trying all day to figure out the Qt\'s Phonon library with Python.
My long term goal is to see if I could get it to play a mms:// stream, but since I can\'t find
If Phonon is not outputting audio or video, but not throwing any errors. You might just have to sudo apt-get install phonon-backend-gstreamer
and also maybe sudo apt-get install libphonon-dev
Phonon uses a backend of gstreamer or vlc silently, so when its not there, no errors but no functionality either. after running those commands I was able to hear sound from phonon on my raspberry pi
Hopefully this will help someone in the future.
