< Playback only: pre-buffering. The server does not start with
* playback before at least prebuf bytes are available in the
* buffer. It is recommended to set this to (uint32_t) -1, which
* will initialize this to the same value as tlength, whatever
* that may be.
*
* Initialize to 0 to enable manual start/stop control of the stream.
* This means that playback will not stop on underrun and playback
* will not start automatically, instead pa_stream_cork() needs to
* be called explicitly. If you set this value to 0 you should also
* set PA_STREAM_START_CORKED. Should underrun occur, the read index
* of the output buffer overtakes the write index, and hence the
* fill level of the buffer is negative.
*
* Start of playback can be forced using pa_stream_trigger() even
* though the prebuffer size hasn't been reached. If a buffer
* underrun occurs, this prebuffering will be again enabled.
