Hello, I am a newbie with this program and I need to ask question about it. I have a problem when I am going to morph my voice. When I change the timbre and pitch graph, my normal voice retains and nothing changes. My Audio Driver is Realtek High Definition Audio. First, I try to configure my Sound Settings. Then, I enable Playback Volume. When I am going to speak in my mic with the voice morph, nothing happens. What should I do? Thanks!

Hi Smith,
In this case, please clarify that the Duplex button is turned on so that you could hear your changed voice output.

Also, please check if AV Virtual Audio Driver is properly installed.
1. Go to Device Manager » Sound, video and game controllers » Double-click on Avnex Virtual Audio Device » In General tab, check if device status is "This device is working properly."
2. If it is not, right-click on a VCSD 7.0 shortcut >> Choose Properties >> In Shortcut tab, select Open File Location >> Choose Driver folder >> Run drvinst.exe (32-bit OS) or _inst64.exe (64-bit OS) (It is recommended to Right-click » Run as Administrator) >> Wail till the MSDOS window automatically close.

Finally, please be more specific on the change you made on PC's Sound settings.
