I have a DVD player with digital audio output.

So i got a digital cable and connected it to my AVR (I think is Audio Video Receiver).

The DVD player is connected to the projection TV using the RCA cables (Yellow, White and Red), with the digital cable from the audio out to the AVR.

Before using the digital cable, TV audio out was connected to the AVR using RCA cable (Red and White), and the AVR was able to project surround sound (alas simple left right sterero with diff modes like theatre, hall), however, now, few events occurred:

1. When I choose Digital Input in the AVR, it says "No Data", and changing the surround modes resulted in crazy humming until I bypass the surround (surround off)

2. The only way to have sound from the speakers was when I bypass surround and choose analog, which (to me) are the sounds from the TV out.

Thus I would like to ask if I had connected the devices wrongly, and how I should connect them.

My equipment are old without HDMI.

What AVR are u using?

Cheers

If AVR says no data, then DVD player is not outputing the digital audio signal.

Most probably an incorrect configuration setting in your DVD player.

Make sure in the audio settings, the output mode is Digital.

In the RCA output, only yellow cable is for video. Red and white are stereo outs. You dont have to connect them to your TV now.

Also try to upgrade to a better video output like S Video or Component (If your projection TV supports it).

just wondering, are you using coax or optical for ur digital output?
