Subject: [PATCH] Set the TCP send buffer size to avoid buffering audio

If the send buffer size is large and the receiver is unable
to keep up, then audio samples will collect on the monitor
and lag will accumulate. As only the most recent sample is
important, reduce the send buffer size to the minimum
AudioRecord buffer size.
