I am using Premiere 8 and Windows 7
When I connect my headphones to the jack at the front of my computer there is no sound when I am working with a project in Premiere. When I performer this action with all of my other programmes then the audio works. If I connect the headphones to the jack at the front of my speakers then they work while using Premiere.
I have downloaded the latest Realtek driver. I checked the device manager and the driver is up to date. Also downloaded the latest Windows 7 Codec.
Is there somewhere in Premiere that I have an incorrect setting?
It is likely an Audio setting in PrE. Look over this ARTICLE for places to look and check.
It is likely just a matter of choosing the headphones, as you are getting the proper feed to the speakers, and then from them to the headphones, when plugged in.
