Question about B&K AVR-507 Receiver

Audio problem with B&K AVR507

My receiver no longer senses the optical audio inputs. When I switch to any of them I get nothing. I hooked up the analog set (white and red) and it now works but you have to switch inputs a couple of times before it does....and no Dolby Digital any longer when available. It use to make a switching sound when you went from one input to another but it doesn't any longer. I have an extensive electronics background and could replace components if I knew what to replace. Any help would be appreciated....the unit is only a couple of years old and heat is not an issue.

Re: Audio problem with B&K AVR507

I have the exact same problem with my AVR 307. Called B&K and they are familiar with the problem. Send it to them and they will upgrade your unit for no charge.

Hi, when I plug my TV's optical out into the Nakamichi AV8's optical input, and switch to "DVD/Optical" (after hitting "Digital Input" buttno) ... no sound comes out. I have...

Maybe assign it?

If the digital TV-related audio actually originates elsewhere (Cable Box?) you could skip the TV and use the Cable Box as the audio source. Nothing is gained by flinging an audio or video signal around the room to be handled (but not improved) by any device. I have no video entering my receiver and nothing but bare bones analog audio going to my TV in case I want to just watch the news or something else lo-fi.

Trying to hook up tv to JVC RX-315 and not sure what to hook up where

Hi,here is my simple solution...
If you want to listen your TV on your Stereo system thru your receiver,
** you need to connect "Audio Output " RCA jacks or "Optic cable output" of your TV
** to "AUX input " or "TV" OR "Any input" of your receiver ( except Phone ) or "Optic Cable input"
** than just switch to respective mode on RECEIVER corresponding your RCA or Optic connection..
There you go..Your TV sound is on the Receiver..By this means whatever you watch on the
TV (
tuner, satellite , Xbox ) ,it's sound will come thru your stereo..

Hope this helps!
Take care and please

Is the digital optical socket at the back of mySony MHC ZX30AV a digital in or a digital out or both way?

It should be the input since the receiver is acting as the audio amplifier. It wouldn't make sense for this type of unit to output optical audio.

Hooking up optical input output

What kind ot TV?

Not sure what you mean by all signals.

Think about this: if your TV had any AUDIO capabilities that were superior to your REAL audio components, why would you need them?

The TV is the end of the line. Wouldn't it make more sense to get your TV-related audio as close to the source as possible? Your BD, DVD, cable and satellite all have high end audio outputs just begging for a place in the Pioneer.

Hi, i have the Denon AVR-2802 reciver. My issue is when i plug my xbox into the dvd compontent inputs, i cant get any audio or video. I was working a few days ago, i had to disconnect the amp, when i...

Component inputs are for video only, and when connected through a receiver then the television also must have a video input coming to it from the video out from the receiver. If you want audio that will be a separate connection from the xbox to the receiver either by digital coaxial cable or optical cable, or composite.

Digital optical output for technics 5.1 surround sound receiver

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

I have a 50 incch samsung tv with samsung surrond sound/receiver/dvd player. I have no voices when we play a dvd but the music plays what is wrong

You need to have the audio from the DVD player hooked up to the same input path on the receiver.(if your running video thru the receiver) DVD audio should be hooked up to either an analog input (RCA cables) or Digital input like Digital Coaxial or Optical. Next to where you are plugging in these cables will be writing like "DVD optical" or "DVD digital". Then, make sure you switch the input of the receiver to "DVD" then it should work fine. If you still have problems post a comment and I will help some more. Hope this helps

Lose audio unless projector is on or unplugging hdmi cable from sharp xr-32x projector. works fine when watching projector

Your receiver is sensing the video source. Try using optical, or coaxial digital audio for an input, this may work.

DVD optical/TOSLINK input no longer working

If it's only the DVD input, and you had tested it systematically, like you'd stated, then the input connector could be loose or defective.
