DirectSound problems - dlls/dsound/mixer.c

[Randall Walls]

Scratch that.... after spending about an hour playing Battlezone 2 
tonight (with patch applied) I noticed that certain sounds (mainly 
sounds longer than a few seconds) would exhibit a strange problem with 
the last .5 seconds of the clip repeating for a random number of times. 
For example:

In the game the units 'talk' to you. One might say "Got it covered.", 
but with the patch applied it comes out:

"Got it covered"
"ered"
"ered"
"ered"
"ered"
"ered"

It might repeat once, it might repeat 6 times, or any number in between. 
The only console messages are the same as I noted before. I can run a 
trace if it would be beneficial for you.
