[chuck-users] WAV playback gets louder with each iteration

[Jack Atherton]

You are adding a new connection from your SndBuf to the dac on every
iteration of the for loop. Either only do this once, near the top of the
file where you set the gain, or also break the connection within the body
of the for loop (i.e. buf =< dac; once you are done with it).
