pa_buffer_attr.fragsize

< Playback only: minimum request. The server does not request * less than minreq bytes from the client, instead waits until the * buffer is free enough to request more bytes at once. It is * recommended to set this to (uint32_t) -1, which will initialize * this to a value that is deemed sensible by the server. This * should be set to a value that gives PulseAudio enough time to * move the data from the per-stream playback buffer into the * hardware playback buffer.
