Re: Audio wont play in audition by Angelo Lorenzo on Feb 13, 2012 at 8:10:23 am
Go to Edit > Preferences > Audio Hardware and make sure you have an output set, then go to Audio Channel Mapping to make sure left and right are mapped to your output device.
This can happen often if you are using Audition with usb speakers or headphones. Your computer sees usb audio devices separately from your internal speakers or normal headphone jack. Once the usb device is unplugged, Audition loses it's output device and mutes itself.
