Usually, switching from built-in speaker on a laptop to head phones is mechanical by just plugging in the head phones. No need to do anything on the PC.
If that doesn't work install a USB audio card. It should come with its own drivers (or you have to download them). Cheap, so worth a try.
Okay so. I came on today and realized that I don't have Realtek Audio Manager anymore hence making me unable to use my headphones jack or have sound come out from anywhere but my computer. I've tried to search the web for hours to find a solution, I have downloaded the file and my computer has restarted and still no Realtek Audio.
My question is, is there an alternative driver or something that is easier to get a hold of that could resolve my issue with not being able to use my headphone jacks?
