Rohan's notes on the sound player/server (slightly modified by Tom Roeder)

[1] This code will currently only receive the first packet and play
it.  I would first advise you to see if you can get the
initial packet playing. The packet size is set by the sender and if
the first packet received is passed onto the sound buffer and is
audible, I would then suggest putting a while(1) loop, starting before
minithread_receive and ending right after the code that's commented as
"Wait until sound finishes playing".  This will play all incoming
packets.

[2] Right now, the audio file link
(http://members.tripod.com/~CotMan/basket.au) I've provided is a 11025
Hz, 8bit-mono file Sun .au format (Green Day - Basket Case). You will
notice that in Sndplayer.c, the buffer is setup with similar
parameters in

    WaveFormat.nChannels = 1;                    // 1=Mono 2=Stereo
    WaveFormat.wBitsPerSample = 8;               // Bits per sample per channel
    WaveFormat.nSamplesPerSec = 11025;           // Sample Per Second

The reason for such low sampling is that minithreads is generally very
slow and therefore we want to send as little as possible to get some
feeling of continuous audio. If you were to switch to high sampling
i.e. 44.1Khz, you'd have to pump through a lot more data and I doubt
if anybody's implementation will be able to handle such data without
the listener experiencing lag. You can alternatively try playing
around with these numbers. For example, they could try converting
their favourite song into .au of 22Khz and trying the same.

[3] The BUFFERSIZE values can also be varied if one finds packets are
getting through reasonably without getting dropped. For example, you
could start with small BUFFERSIZE values and keep increasing it (to
get rid of lag on the listener's side) and at some point you'll begin
to experience a lot of losses and can cut back. This value is purely
emperical and depends on the implementation, where and when the test
was tried out.

[4] I remember trying this out on csuglab machines and for some reason
I couldn't get any audio to work on a few machines but it did work on a
few others.
