I am trying to get audio from my TV (when using its built-in DTV tuner) to play through my AV Receiver. It seems like this should be pretty easy but so far I can't figure it out.


What I have is a Samsung LN52B750 and Denon AVR-2310CI connected via HDMI. I assumed the single HDMI cable would be all I needed but when watching TV and the Receiver's source set to TV I get no sound. The TV is set to "External Speakers" and the receiver is set to "Amp"


Next I decided to try adding a digital optical cable, but I still get no sound when TV source is selected. As a test I tried assigning the OPT1 input to another source, with that source selected and the TV on I get sound (so I know the TV is sending sound correctly and the cables work), but with OPT1 assigned to the TV source I get nothing. (this is a workaround, but undesirable because I want the TV button on the remote to be what you press to watch TV, not something else. And HDMI CEC sets the receiver source to TV automatically)


At this point I thought maybe the receive expected sound through the HDMI cable but the TV wasn't sending it, so I disconnected the the HDMI cable so that the only connection between the two was the optical cable, still nothing!


I am at a complete loss. The manual doesn't indicated any custom settings that need to be set and I have tried everything I can think of. If it wasn't for the fact that everything else works flawlessly I would start to suspect the receive was defective. Any guidance would be a big help!!

Audio/video with an HDMI 1.3 cable only travels one way ... from the AVR to the TV so you won't get any audio with an HDMI cable connected only to the Monitor Out jack. In order to get audio to the AVR from the TV (when there is no cable/sat box involved), you would connect an optical cable from the TV's optical out to OPT1 on the AVR. The default for the TV input source is OPT1 so you should be good to go. Try the TV button on the back of the remote as well. If neither works correctly, then you might want to Reset the microprocessor (p. 70). Also try turning HDMI-CEC on the TV to OFF.

Thanks for the HDMI info, that brings me down to troubleshooting the optical connection. At this point I have it connected to OPT1 with that port assigned to TV, not working. If I assign that port to AUX then I get TV sound on that source, but assigning it back to TV leaves me with no sound. I will look at resetting the micro processor.

I figured it out!!! The TV input mode was set to Ext. In instead of digital. For some reason that makes no sense to me, auto is not available for the TV source so even though I had the inputs assigned correctly they where not being used. I find it odd that no where in the manual does it even tell you to connect a digital cable to the TV, let alone that this manual change needs to be made.

The default Input Mode for the TV input source is "DIGITAL" so not sure how it got changed to "EXT IN." Connecting the TV as shown on p. 14 in your Owners manual normally should be a plug-N-play connection as there should be no other setting changes required. At least you figured it out and now have it working correctly. Good job.

Thanks for all your help. Yes, I read page 14 about 4 times trying to figure this out. The part about connecting an optical cable falls under the "Connecting Devices not Equipped with HDMI terminals" which was what led me to believe the HDMI cable was all that was needed. Perhaps when I powered on the reviver for the first time it detected no optical cable and switched the mode to EXT IN automatically. Who knows, I'm just glad it works now!


From what I understand HDMI 1.4 will support the audio back channel, that will sure make setups like this a lot cleaner!


PS: Not sure if you are just an Denon enthusiast or if you are affiliated with them in anyway, but either way you will have happy to know I am fully amazed by this receiver!! It sounds amazing and the power is so clean!!

EXT. IN on a Denon overrides whatever digital assignments have been made. It tells the receiver to ignore the usual input assignments and find the audio on the external input jacks. EXT. IN is normally used with outboard decoders such as SACD, DVD-Audio, and BD players when connected to receivers that lack HDMI.

I'm having a similar problem but my Denon does not have an had I port. Am I screwed?
