question - want to get audio out in 5.1 channel surroundsound into my sony hometheater system . ?
my progress till now - 1) my sony home theater has both hdmi in and optical in .. tried with my tv and other divices .
2) till now i am using audio jack 3.5 mm for audio out .. working fine but it's 2 channel ...
3) if i use hdmi out of lap .... it works fine with my sony screen for video out in 1080p .. but if i connect it to my home theater for audio out . it doesn't work . my home theater shows a hdmi device.. but in lap music keep on playing in speaker as if no hdmi is attached .. [ so may be my lap has only hdmi video out not audio out or my hometheater has in from screen etc but not from lap ] ..
4) is my lap is optical audio out compatible or not .. ?
if there is no way to get 5.1 channel out of my lap .. can i use any external device to do so ...
also in my lap .. play back devices it's like this [ in pic attached ]
i can't see any digital output option here .. or any other option where 5.1 channel device could be connected ..
so do tell me anyway possible i can do it . . . or if not any external hadware i can do .. plz use specific detail understandable to non tech user like me ..
