I plugged my Sony speakers into my My new HP Envy 700-214 line out but it does not power the speakers or earphones. I then plugged them into the second line out socket which is on the back of the desktop computer. No results here either. I was able to get a different earphones to work using a USB connection. My computer has Windows 8.1. Is this yet another Windows 8.1 problem or is there a problem with the HP drivers or the line out sockets or the audio chip on the motherboard?
Thanks for any tips you may be able to offer.
