Audio output from amp stopped working on 1 input but others fine

This will depend on the Blue ray player and other equipment. For a direct connection to the receiver, if your player has either type of digital audio output (coaxial or optical), get the appropriate cables. Then connect the chosen cable between the Blue ray player and the receiver. Connect the Blue ray player to the TV with an HDMI cable. See page 10 of the manual, available at http://pdfstream.manualsonline.com/6/69f43064-f593-49b8-8d4a-23174b496e65.pdf , to see the connections for the audio sources. (I'll assume your Blue ray player doesn't have component video out or you would use the component audio to the receiver.)

If your player doesn't have a digital audio output, check your TV audio output. You can get the same result by sending the videos via HDMI to the TV and using the TV audio out to the receiver. Set the audio source to TV and leave it there for both TV and Blue ray and DVD videos. (Sometimes there could be a slight delay in the audio compared with the video signal when you do this. I've never noticed it with my Blue ray player signal going to the TV and the TV digital audio out to the Denon receiver.)

If you can't send the audio out to the receiver from either your Blue ray player or TV, then you will need some sort of HDMI audio extractor. You can find models with Analog Audio Out, Digital Audio Out or both. ( https://www.amazon.com/J-Tech-Digital-Extractor-Converter-JTDAT5CH/dp/B00BIQER0E lists units with both types of audio output. One models requires a 3.5 mm to RCA audio adapter.)

I hope this helps.

If it is the radio you are trying to get make sure you have an antenna that is strong enough and can receive the signal. With a digital tuner it requires a strong enough signal to capture any channels.

Hello, I am sorry about your issue. Did you make any changes to the output resolution on the Wii. The output must be at 480i for the receiver to up-convert to HDMI. If there is a problem with the receiver I suggest a work around by connecting the component [red,blue,green] video outputs to the TV and the audio connections [red, white] to the receiver. Thank you, Onkyo USA

the blue ray player should have a audio output generally RCA audio.
just get this cable RCA Audio from the blu ray to a input on your receiver eg. dvd,cd,line 1,line 2 whateva your receiver inputs are lol

Check the manual for "Volume offset" at the input mode. I'll pull the pdf on the unit, If I find it, I will send the instructions. Hope this helps

Before you buy anything try checking the AUDIO Settings in the Menu of Each Device (Mostly TV) and see if they are set to PCM or BITSTREAM. HDMI is mostly set to PCM while Optical is generally Bitstream. The TV may be set to the opposite of what it needs to be. I would try to get PCM to work first cause it is Better, If not then set what you can to Bitstream and it should pass. Also check in TV Menu for SOUND OUT or AUDIO OUT or SPEAKERS. Some TV's have a problem passing Audio through when they are already Outputting them to it's own Speakers! I Hope this Helps out!

If you don't have one, the manual is available online: http://static.highspeedbackbone.net/pdf/AVR-488-OM-E_101.pdf

Suggestions:

1. Reset to default values. Per page 36 of manual: 1. Turn off Power. 2. Press Power while simultaneously pressing Speaker A and Speaker B. 3. Once the display starts flashing at intervals of about 1 second, release the two buttons.

2. Make sure you have AM or FM radio reception. This makes sure your speakers, amps, etc are connected and working correctly.

3. Connect DVD player to HDMI 1 in and TV to HDMI Monitor Out.
Play a known good DVD that works when you connected the DVD directly to the TV via HDMI.

Select the DVD/HDP input on the receiver and play the DVD. You should not have to perform any input assignments, etc. It should just work, as HDMI1 is the default system setting for DVD.

4. If possible, obtain a STB with HDMI out & repeat step 3 using the HDMI2 TV/CBL input. Keeping the signal path all digital (HDMI) will give you a better picture quality than forcing several analog to digital conversions (component video is analog).

4A. To use the component connection, first test by connecting the STB directly to the TV via component video/audio if possible. This tests that the component video output of the STB is working correctly.

Next, remove direct connection and connect via receiver. Connect STB to receiver as shown on page 13 in manual. Connect component video output from STB to component video input #2 (tv/cbl) on receiver. Connect the STB audio output to the corresponding tv/cbl audio inputs.

Make sure nothing is connected to the HDMI2 input or to any other TV/CBL inputs (composite video, s-video, digital coax audio).

Now select the TV/CBL input and turn on the STB. You should have both audio & video.

Are you using the HDMI for video AND audio or just video? Are you using the reciever as the video switcher by routing your devices into the amp and then from the out of the amp to the TV and then back to the amp from the TV HDMI output and the digital output? You may have a loop going on and the amp can't handle it.
If you are coming out of the TV with both HDMI and digital hooked to the same input selection on the amp and have the amp set for auto signal select, it could be throwing the amp for a loop and causing it to freak. From what I can see in the specs for that amp it has 2 HDMI in for connecting a HiDef Sat/Cable box, a DVD or Blu-Ray player or a gaming console, and then 1 output to the TV. HDMI handles both audio and video. Disconnect the digital cable and just use the HDMI for both audio and video.
The optimal set up would be as follows:

With a cable or sat box with HDMI out, go to the HDMI input to the TV. From the TV use either HDMI OR digital to the amp, not both. If you have Blu-Ray or HDMI DVD, connect that to the other HDMI input on the TV.

If the TV has only 1 HDMI input then connect the Cable or Sat box to one of the amp HDMI inputs and the Blu-Ray/DVD to the other and then from the HDMI out to the HDMI in to the TV with NO audio cable from the TV to the amp. Then use the cable remote to change channels.

See if one of those connection maps works for you.

If you need more help, let me know. Include the TV model and the digital audio cable interface type, whether it is optical or coax. It would also help knowing if you are using a Satellite or Cable box and which one it is.

Cheers

Hi, I have just completed this installation myself.
You are correct, HDMI to Amp Input from Bluray and then HDMI from Amp output to TV. Coloured cables are not required to operate the bluray now.
Good luck

Is Yamaha HTR-640 a receiver? Try HDMI from PS3 to receiver or Sony HDTV. If HDMI from PS3 to receiver the you need and HDMI from receiver to out Sony HDTV. You could connect everything to receiver and HDMI out to HDTV. You can not have an HDMI cable AND an optical cable coming out of the PS3, only one or the other.
