No sound when rendering .avi or .mpg

I am using Video Factory 2.0 and attempting to render a 4 minute video to put onto VHS tape.
When I play the video in VF the sound is fine - a sound track recorded in Cool Edit as a 44,100, 16 bit stereo .wav file. but when I render the file and play it in any player, there is no sound...
This has just started - there was no problem yesterday, and I haven't loaded any new software on the system.
When I render the file it is trying to convert the wave to 48k from the 44.1k - is this the problem area?
any suggestions would be greatly appreciated.
System:
Windows 98 2nd ed
AMD athlon 1.3 ghz
512 meg pc133
source is on 30 gb, 7200 rpm disk
rendering to 100gb, 7200 rpm disk
captured with ATI all - in - wonder pro card...
Thanks
Steve

Since you are going back out to VHS I'll assume you are usually rendering as .avi.

Click the 'Advanced Render' button (in videofactory2) when you are going through the 'Make Movie' dialog. Specify .avi as your type, click 'Custom.' You'll see three tabs along the bottom of the splash screen. Click on 'audio.' Make sure the sample rate you are rendering to is specified as 44,100Hz, 16 bit, and the format is PCM (uncompressed). Run your .avi render and see if that changes anything.

When you say you are playing this back in a player, what players are you using? Do you have the volume turned up in the player itself?

While I prefer Cool Edit 2000 to Sound Forge XP by a long shot, when working with VideoFactory, I have found it much easier to use SFXP as the preferred sound editor. It automatically recognizes the sample rate, and you can even see the video inside SFXP.

However, I also found that in some circumstances the sound just goes bye-bye when rendering. I tried to "write to disk" using AVI/DV settings, and the sound was lost. When I did the Print to Tape option, it came out find. It also writes the file to the hard drive, and you don't have to go on to the step where you are actually writing to the the tape. I am curious, though, why the former method lost the sound.

Why would you want to render as 44.1 KHz? My DV camera records at 48 KHz, and this is the way I keep it from start to finish.

I think my system is sick...
and I'm a klutz...
but,
(1) I recorded the song at 44.1k because that was the default for Cool Edit 96 (shareware). I use the cool edit program because I don't actually make too many videos - just learning and experimenting, and don't have the bucks to pay for sound editing software.
(2) When I saved the wave file, I saved it as a 'Microsoft ADPCM *.wav' instead of 'Windows PCM *.wav'. Don't know if this has anything to do with any of my problems.
(3) I'm outputting to a stereo VHS VCR using, gasp, rca jack composite cables using my ATI all-in-wonder card. I play the video in either Windows Media Player or Power DVD, maximize the display, and record it on the vcr. It has worked in the past fine, but for some reason I had no sound.
(4) The problem has pretty much resolved itself, for now, as I can record with sound. The strange thing was that if I created a new project and added the rendered .avi file, it would play fine in the preview window.

My system is acting up now - I'll put that in a new post...

Thanks for the input

Definitely do not save as ADPCM. It is a compressed format.
