My Roku box works fine when connected to my TV directly, I then send the audio to my Samsumg compact home theater receiver (a $250 cheapy 5.1 system) and its OK for movies....but when on Pandora....the audio is fairly low quality.
Im wondering if I should be able to connect my Roku box directly to my Samsumg receiver that sends its signal to the TV via an S video cable and if I do that, if it will improve the audio output I am getting.
I've been messing with it this morning and so far nothing at the TV.
Yes. You should be able to route your Roku through the receiver, to your television. However, S-video, as the name implies, only carries your video signal. Depending on the inputs/outputs on your receiver, your can either go HDMI all the way: HDMI out from the Roku to HDMI in on the receiver, HDMI out of the receiver to HDMI in on your TV. If you don't have HDMI inputs/outputs on your receiver, your next best bet is component (Red, Green, Blue connectors) all the way through. The best bet after component is S-video and the last option is composite (yellow connector).
If you are able to go HDMI all the way through, that will carry your audio and video signals. If you go component, S-video or composite, they only carry video. You will have to also run an audio cable (red and white connectors) from the Roku to your receiver.
