This thread interests me because I have this problem but only in a semi-form. The sound plays okay, but only if I'm pressing play, and off it goes. But if I'm trying to finetune the lip sync, then there's no sound. That is, if I'm advancing the keyframes using the keyboard arrow keys, or moving the cursor along with the mouse, then the lips move but there's no sound. No reason why that I can see. Have updated NVidia drivers, restarted the computer, shut down and restarted, all to no avail. This is my 11th such video with exactly the same character, and similar audio file as previous ones. So I'm at a loss.

Has anyone else experienced this? Oh - btw it's Crazytalk 8 Pipeline.

I bought Cartoon Animator 4 Pipeline yesterday.When I try to play sound effects in the project phase I hear nothing.Fortunately, however, I can hear the sound effects in the video after it hasbeen rendered. See the following example:

I have Windows 8.1 and I could not find "Hardware & Sound" which was mentioned in the fix suggestion by Peter(RL) regarding Crazy Talk and Windows 10.    

Hi Roger

In Windows 8.1 you can find Hardware and Sound by running a search for the Control Panel. If I recall in Windows 8.1 you just have to start typing while you are on the Start screen. Then follow the advice I gave previously to see if that resolves the problem for you.

Turns out the answer to my problem, in case anyone comes here with a similar hassle, was that audio scrubbing has to be activated. Not sure why. Took me days.

It seems that my error was because I changed headset or because I used my 3.5 mm headset. I fixed the problem by removing the 3.5 mm headset, plugging in my USB-headset and restarting the computer. Now the sound effects work fine! :) 

What is audio scrubbing I cant find
Thanks

Hi Riverbud,Audio scrubbing is when you move along the timeline faster than just playing it normally. You can move the place-holder along with the mouse, causing the voice to suddenly gabble like a chipmunk or you can move it more slowly with the arrow keys to find out exactly where e.g. the mouth isn’t closing for an ‘m’, ‘b’ or ‘p’ sound.

Thanks but I tried with on and off but no luck at all I did find that when loading any audio it says it can't connect to my audio card. but only has that problem with Reallusion and works fine with other programs. I never had this problem with any programs. Support also could not help with it because they said it must be my sound card even though it works fine on other programs. I see here in the forum it is not just me with the problem. Thanks for the suggestion

Hi I returned my Crazy talk pipeline, never was able to find the problem it's to bad I really like the way it work I just wanted the sound to work. Funny I have a older version 7 and it worked fine, I had it for 2 years with no problem with it
Thanks 

This happened to me.  It is very unacceptable.  Pc has sound with everything else.  Reboot does nothing!
