I am trying to play a sampled format 2 'snd ' resource using the sound
manager.  I open a channel using the sampledSynth, load the resource,
issue a bufferCmd using a pointer to the sound buffer portion of the
resource, and get sound-- but at the wrong rate.  I have tried issuing
a rateCmd before playing the buffer, but it seems to have no affect.
Neither does ampCmd, although perhaps the sound has to be currently
playing.  I have tried issuing soundCmd before the bufferCmd and this
seems to make no difference.

I do things in this rather awkward way because I want sounds to play
asynchronously of other activity (animation) and I was having trouble
getting SndPlay to handle format 2 'snd ' resources at all, let along
playing them asyncronously.

Could someone please tell me what I am doing wrong?  Thanks.
