[pulseaudio-discuss] [PATCH] Fix wrong input device in module-waveout

Both input and output device were chosen with the same device number.
This is problematic as those numbers don't have to correspond.
Additionally the input device was named after the output device. This
commit adresses both issues by providing specific parameters for each
type.
