after spending most the weekend trouble shooting why i have no sound when i connected pc to tv thought i share with you my findings.
initially i thought it was the jack audio cable or tv settings..,and got very confused with tech advice.. but after it works fine in my ipod i looked at pc.
i simple plugged in jack to jack connecting pc to tv. went to control panal/ sounds and updated driver./ configure.( jack must be plugged in to the audio black input at rear and pc headphones,. pc searched online, re booted and its working! hope this may help some of you . . let me know if this works for any of u
