Denon avr dolby problem - Denon AVR-1801 Receiver

Use an optical cable.

Be aware though. Your TV has a DVB-T tuner. It picks up the Freeview standard definition (SD) channels, but not the Freeview HD ones. Dolby Digital sound only comes from the Freeview HD channels.

Your TV will pass Dolby Digital from any source connected to a HDMI port to the Optical Out. It will also pass DTS. But the internal Freeview DVB-T tuner doesn't generate Dolby Digital, just stereo and stereo with Dolby Surround encoding where you use ProLogic II for decoding.

The owners manual can be found at many sites on the internet if you google for Denon AVR 1513. One site is amazon.com.

What I suggest is that you reset the receiver as you mentioned. If you look in your owner's, there will be a procedure that says, "Return to factory default, or Reset" I believe you have it set wrong, or are not providing it with Dolby Digial signal. Dolby Digital, is not processed by the DSP board(Digital Sound Processor), which handles the THX, Neo, and every other format. Dolby Digital, is one of the earliest form of Home Theater. It has to be processed through the 2 RCA jacks(left and right). It is really not used anymore, in light of Dolby Pro Logic, THX and others.

The Dolby digital signal is outputted only through the Optical or Coaxial socket of the CBL box. you will have to get an optic fiber or coaxial cable depending which cable box you have and connect it to the digital input of the Denon receiver. The Denon's digital input are already assigned at the back. Eg: Optic input might be labeled CD so if you are connecting the CBL box to the optic input remember to select CD on the Denon to hear the cable sound, same goes with the coaxial input.

It sounds like your cable signal is dropping out. Take it up with th carrier.

The processor that creates the surround is all on 1 chip so sounds like a software issue.

Call Denon to see if they have a firmware update for your unit this usually is free and may fix the problem

pres the prologic button more that ojne time

Dolby signals are passed via either an RF cable or optical link. Both the receiver and player need to have these switched on and that they are passing the correct signals. You clearly found the correct setting for the TV sound link. Now you just have to find the one for the DVD player.

IT IS ALWAYS BEST TO CONNECT ANALOG AUDIO IN ADDITION TO THE OPTICAL, COAXIAL OR HDMI AUDIO CONNECTION. IF USING OPTICAL OR COAXIAL CONNECTIONS BE SURE TO CONFIGURE IT IN THE RECEIVERS DIGITAL ASSIGNMENT AREA IN SETUP.
ALSO, ON THE FRONT OF THE RECEIVER IS AN INPUT MODE BUTTON, PRESS THIS BUTTON UNTIL AUTO IS DISPLAYED

prologic is a form of dolby digital, the 4.0 or 5.1 (versions I and II respectively) to be exact. the type of dolby version is determined by the source disk. the reciever may expand a dolby digital signal into 7.1 but it is actually a 5.1 standard, as is prologicII
