My old headphones worked fine up until a couple of months ago but were broken after 12 years of use. I plugged in a headset with a mic and my friend could hear me but i could not hear her on comp. Today I bought new Sony headphones and I can hear a CD when I play it and messenger alerts etc., but when I try to play a video on youtube there is no sound. My Vista system came with Realtek High Definition Audio. In the control panel under sounds and the Realtek Sound icon, it should a green tick by the speakers but the headphones icon is greyed out with a red arrow pointing downwards and says "Realtek HD Audio 2nd Output2 Not Plugged In. I've tried plugging the headphone mini socket into all 6 inputs but still no sound from the web. Does anyone know how to fix this? and if not, is there some software I can download to my Vista computer to get sounds from the net?
Many thanks in anticipation for your assistance.
