  I almost wonder if it is worthwhile for the server to know/care about the 
client sound settings - it keeps the server simpler if it doesn't.  The only 
reason it makes any sense is some bandwidth savings, but the savings for this, 
especially for the backgrounds ones on the map, is pretty trivial.

  A fair amount depends on the format we use for the sound files.  For the 
current unix client, I think the current sound program could be used pretty 
easily with a few minor modifications (basically, it just keeps copying in the 
sound data to the sound card).

  That sounds good.
