When I connect to my Vaio external sound devices, such as speakers and headphones, only from one of them comes the sound and not from both, meaning they play mono.
This despite the fact that the built-in speakers play as they should, that is suround.
I have tried several external speakers and headphones, which play right connected to other notebooks and mobilephones.
I realised the problem just one week (approximately) after I bought the vaio notebook (I am not sure if there already was this problem from the very beginning, since I didn't try external speakers immediately)
Any suggestions?
