Well for some reason I was missing around and I tried connecting my vista laptop to my tv via the lead I got with my nokia N96!! Werid I know!
Now my sound has gone muffled and it seems be be coming from one side only (left)
However when I plug external speakers in, it is the same, so I dont think I have blown the laptops internal speakers, I just think I need to balance the sound between the left and right again.
They are realtek HD audio, but i do not know how to change it back??
