Some sinks (e.g. module-alsa-sink) do a lot of thing, but at the heart of the sink is always the transfer of pcm data. You could look for ideas of how to implement this in module-oss-sink or module-pipe-sink. Most sinks also try to account for clock differences between the sink clock (audio hardware samplerate) and host clock (computer and pulse's samplerate) beyond simply dumping audio data at a fixed rate. > Regards, > > Dengyi Wang Maarten
