Things todo:
- Cleanup Pulseaudio references so they all refer to one thing only, e.g not PA/Pulse
- Fix table of supported formats (we should include all formats that xbmc supports and mark them as not supported and or limitation, so there is a clear distinction when comparing to alsa
We should do the above because we must declare the obvious and not expect or assume everyone has same knowledge as the people developing. Personally I dont want to see questions like how about lpcm or how about this format... or that format.
- Clean-up instructions get better formatting going
- Grammar/punctuation.
[Comment from jjd-uk} Please try and get the pavucontrol screen images replaced by English versions please.
