Python audio library

[hbknjr]

I am creating a project that has a module which requires audio playback.(similar to a music player)
So I'm looking for a Python audio library that:

1- Supports mp3 and Ogg file format
2- Platform independent or supports Windows and Debian(Linux)
3- Support play, pause, and seeking.
4- Well documented and simple API.
5- Return signal on playback completion.


Few I tried:
a- PyQt4 phonon-> Not working on windows, getting errors.
b- Pydub - doesn't have pause and seeking.
c- Simpleaudio - supports only wave.

Please suggest.
