HK AVR35 Receiver - Dolby Digital not displaying or working

HD broadcasts by TV stations are often broadcast in Dolby Digital. If your TV can output Dolby Digital or HD then you will need to have the TV connected to the receiver via either the optical in, or the coaxial in. If the receiver can get the Dolby signals via the Coaxial and the TV can send them via a Coaxial socket it should work. Don't forget to set your HD set to output Dolby signals. If the TV or Receiver can only send Dolby via the optical you will have to use that. Optical cables can be picked up cheap these days. I have seen them in pound shops!

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.

To get DTS and Dolby Digital sound you will need one of a few types of digital cable to connect the digital output on a device to a digital decoder or receiver. One type of digital cable is the SPDIF Coaxial, which is a single cable that can transmit high quality digital audio. Another cable for digital sound is the Toslink Optical cable which uses plastic or glass fibres depending on the cost to transmit light which is then decoded into sound information. With optical cables the signal can break if the cables are bent too much. The other cable that can be used is the HDMI cable, this is used to stream HD video and HD sound formats such as DTS HD Master Audio and Dolby True HD, these can of course stream the standard Dolby Digital and DTS signals, but for what it is worth I would recomend a SPDIF Coaxial cable. These can be found at hi-fi shops and places such as Maplins or Ebay. They are also cheaper than the other digital cables and more reliable than optical ones. Any type will do as long as you have a decoder or home receiver which can convert the digital information into sound. Infact you can use an RCA composite cable and connect that into the coaxial ports at either end. This will transmit the digital information, but not as good quality as a proper coaxial cable, but you still get the DTS and Dolby Digital formats with full surround sound. I hope that this helps.

Each digital input is assigned a name and a function by you. You have to dig out the manual and assign the digital inputs.

My $.02. Why do you not want to use the coaxial imputs? There is no functional superiority of one over the other BUT coaxial is a) cheap, since it uses standard RCA cables; b) adaptable, since you can splice or split them among two devices; c) not delicate or prone to failure due to tight bends. I share one coaxial input between two digital device with an RCA splitter cable. Just have to make sure to turn the one I'm not using OFF. Try that with optical.

I have the 405 as well. My TV has an optical out and I run that straight to the 405 optical input. I set the input selector to DVD/CD (not DVD)and presto! TV audio out my speakers. It all comes down to the audio connections on your TV.

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

you can use the headphone jack just get an adaptor to change from the headphone type to RCA type. adjust the volume of the tv to 3/4 of the way to give line level to the stereo, use an aux input on the stereo. if you had a suround sound dolby digital / DTS receiver then use the digital coax out to that type of receiver, but since you have an anolog 2 channel receiver you must use the only anolog source (the headphone).

I had the same problem with my 321 system. The fix is in the cable box settings. You want to change the Digital Out on the cable box..my choices were HDMI....Dolby Digital..and None. Choose Dolby Digital and it will show up on your Bose 321 display. I also have my cable box connected to my bose system via optical digital cable...and a digital coaxel cable from my dvr to my bose. Change that output setting on my cable box took care of the PCM 2.0 problem for me.

Hi, It sounds like your receiver is still looking for audio on the coaxial connection, rather than the optical.

1. Make sure the optical connection is between your DVD player and the LD/DVD Optical In on the back of your receiver.
2. If you have a monitor connected to the receiver to show the on-screen display, click Setup from the main menu, click Input Mode, then, next to LD/DVD choose Optical. It may be set to coaxial, analog or auto.

Alternatively, choose the input source on the front of your receiver (LD/DVD), then press Input Mode button (bottom right, near the input selector) till it displays Digital Optical.

If all else fails, reset the receiver by:
1. Turn off the receiver
2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
3. All Clear should appear on the screen.

Use caution, however, as this will erase all the settings in your receiver.

If you have an HDMI cable plugged into the cable box it may only output 2.0 on the digital audio output. Set the HDMI audio to off or 2.0 and then set the cable digital out to Dolby.
