I downloaded the demo of Acid Pro 11 and installed it. However, I get no audio output at all. I have tried all the settings under Options> Preferences and nothing. I have Sound Forge Pro installed along with Magix Audio and Music Lab, along with two other audio editing programs. All of the others work just fine, but Acid is totally silent. I am trying to get to a multi track editor where I can produce (induce, if you will) harmony. I am using Windows 11, and there is an AMD audio device (from the video card), the built in Realtek HD Audio and a Bluetooth adapter, Avantree Privia. Most notably all the other editors work fine with perfect audio out, but none of them will give me the multi track mixing with the ability to add harmony. Thanks for your response.
