there is a bug in the WaveFile class in the SetVolume() method.

you used int32 when u should have used Uint, then when u sent it with max volume as hex value (&HFFFF) on both chans there is an overflow, if u send it with -1 it works ok i think.

i found it on the VB.net port, maybe it exists in the C# one as well.

but bug or no bug thank u (all?) for this nice time saving class.
