wmv9 runningn without audio
 

I found the other thread on the audio problem and downloaded the pack. No love there.
I am running MWv10 and it plays the setup fine. I must be missing something silly and any help would be appreciated. Here's the workflow:

Exporting video and audio from Avid Express Pro software in this configuration:
Windows Media Video 9 720x540 dvntsc4:3 1500 kbps
Window Media Audio 9 Voice 1pass 20kbps/22khz mono (highest setting)

BSPlayer Pro is playing the video wonderfully well, but the slip is silent. If played in WMPlayer, audio is fine. Any suggestions?
