same here...
I'v tried different versions of WAV-files on Poser 7and now 8 but it never worked for me.

That's interesting, because I've been able to use WAV files in my P7. I"m on a Mac. Think that might make the difference?

I received this response

** Response (Matt Ko)** 07/01/2009 10:02 AM Do you have a nonstandard audio setup?

There was someone else who experienced a similar issue in Poser 7 where the WAV file would work perfectly fine when I test it on my end. It turned out that the person was using a nonstandard audio setup (in particular they were using an audio splitter that was causing the problems - after removing the splitter, everything worked fine again).

So if you have a nonstandard audio setup, you should remove the nonstandard components and test it only with a standard setup.

You should also test it using one of the WAV files that come with your Poser installation rather than using a WAV file from a different source. If the WAV files that come with the Poser installation work fine, but your third party WAV files do not, then that would provide some additional information about the problem.

I get that once in a while.

I recreate the file.  It gets corrupted somehow.

If it's something I create in a TTS program, I cut it again.

I don't know what your source is, but if it's something you've downloaded I would download
it again.

For some strange reason, I've also found that if I've used that same file in another
program, like Sony Movie, it won't work in Poser.  

No. Sorry...
I've tried some different ...sub-formats (? - I don't know the english word for this) of wave-files (compressed, uncompressed, wave-mp3, 16-bit, 8-bit and many more) using conversions made with db-poweramp.
And none of the wavs will work.

Can I ask what the source of your files are?

Is it something you are recording yourself?

Not that it should make a difference, but I've only ever used a Text To Speech program and
have been able to quickly rectify the problem by recreating the file from the existing text.

Seems like it should be more simple though.  A WAV is a WAV once it's saved.

Sorry I couldn't be of more help.

 I have the problem with Talk Designer and clips created with TTS, or another Text to Speach software. 
But in Mimic pro run very well, but Poser  no read the archive sound but run very ok the poser file created for Mimic. 

I've never used Mimic.

I did have another thought though.  But maybe you guys have tried this already.

Simply running your finished WAV through another program like Audacity.  It's a free
download.  Maybe what comes out the other end will be compatible.  Ya' never know.

Bummer though.

Good luck!

Same problem here on Vista64

A standard pcm wav file should work. I had the same problem(Vista64). It seems it's how windows takes it to the sound input(known at smith micro).
This helped at me: I pluged in an external thing like a headphone to the soundcard's line-in and looked in the audio settings to see the record channel is active with the line in connected device. For me it worked too with only a plug and cable without any device at the end of it - very strange. I can't describe the special technical reason here - but it works.

Thanks whompie you're right!!!!

Just pluged an headphone in the mic line and now it works

That's an amazing way to resolve a bug but it works
Strangest bug BTW

Thanks again :)

This happens since I started with Poser 7 but only on Vista(64) I don't know if it occurs on Vista 32.

I use XP SP3 and this problem not ending

Another thing that helped to me was a small little USB-Soundstick. 
Absolute crazy.
