I'm trying to convert an AVI file to WMV format using Windows Media Encoder 9. I have two machines - WinXP Pro 32 and Win7 Pro 64 - with Windows Media Encoder 9 and K-Lite Codec Pack installed on both machines. Basically, everything is "identical" between these machines as much as it can be considering that one is XP 32 and the other is 7 64.
When I convert a video on the WinXP machine, everything works fine - the audio level bars in WME jump up and down during encoding and the final resultant WMV file has audio. Meanwhile, when I attempt to covert the same video using the same conversion settings on the Win7 machine, the audio level bars in WME remain at zero at all times and the resultant file has no audio.
I use identical conversion settings on both machines: conversion for Windows Media Server (streaming), DVD quality video (CBR), CD quality audio (CBR), no resizing of the input.
On both machines the FFDShow Audio icon appears in the tray during the conversion process. If I open the FFDShow Audio config dialog during the conversion process on Win7 machine, it shows some dynamic decoding statistics, which seems to imply that the audio codec is "working". Nevertheless, the audio never reaches Windows Media Encoder (audio level bars remain at zero) and the result has no sound.
On both machines the original video plays fine (i.e. with sound).
This is probably a very basic question, but what am I doing wrong? Is this caused by the Windows Media Foundation architecture in Windows 7? How can I make Windows Media Encoder 9 work under Windows 7?
