    Hello.

    I bought a Denon AVR 2113 receiver and an Optoma 27HD projector.
    How to connect the projector so that the sound comes from the receiver and not from the projector?

    Thank you very much for help.

    I know it can be weird but not everyone understands it. When I connect my computer to a TV there are no markings, only 1 HDMI and everything works. Here I have an HDMI cable connected to input 2 on the projector. In the receiver, I threw it under every channel - but there is never sound, that's why I write.

    I finally got the answer:

    Unfortunately, the HDMI connector on the projector is an HDMI input, so you can't send anything through this connector. You can output audio using the JACK (audio out) connector.
    Pity and thanks for help

    Hmm, something's wrong with me ...

    When the computer is connected to the amplifier and the HDMI output on the amplifier to the projector's input:

    - no sound at all?
    - is the sound in the computer speakers?
    - video passes without a problem?

    Having connections as above , please check the audio card settings on your computer, i.e. check that
    which audio device is currently the default device.
    There's a sign there.
    It is advisable that the computer plays a movie at this time.
    Is this computer a "tin" or laptop?

    hello - I send sound from computers / phones via Chromecast to the projector.
    Sound is currently being output from the projector (built-in speakers)
    I mounted the projector with an HDMI cable - but no sound is made in any setting.

    This answer I got from boys from omawiamy.pl - where they described this projector (youtube)
    Unfortunately, the HDMI connector on the projector is an HDMI input, so you can't send anything through this connector. You can output audio using the JACK (audio out) connector.

    Well, there is no need to "pull" the sound out of the projector.
    In particular, if we are talking about a wired connection.

    But if a colleague does not deign to answer the questions asked to solve this problem, well ...
    Only you can wash your hands ...

    I do not quite get it - so you can send a sound?

    nowhere near connectors does the ARC description appear (also in the projector's manual)

    heh ...

    The goal is to get a picture on the projector and sound in the home theater, right?
    If that's the goal, then there is no need to deliberate over "pulling" the sound out of the projector.

    There are other routes to achieve this effect.

    ok - can you expand what you mean with other options?
    We are talking about a specific projector (Optoma 27 HD) and receiver (Denon AVR 2113)

    Thanks

    I know, I read this topic carefully.

    I could, but to check them you need cooperation.
    I posted an entry (# 10) and I do not see an answer to it so far.
    And some information is necessary to solve this problem.

    But the options I mentioned only apply to wired connections.

    In such cases, I want to help.
    I do not intend to "get" the exact answer from the author - I wrote about it above.

    I wish you success in solving the problem.

Topic summary

✨ The discussion revolves around connecting a Denon AVR 2113 receiver to an Optoma 27HD projector to ensure sound output from the receiver rather than the projector. Users suggest using an HDMI cable for video and audio transmission, but it is clarified that the HDMI port on the projector is an input only, which does not support audio output. Instead, audio can be routed through the projector's audio out (JACK) connector. Participants emphasize the importance of checking the audio settings on the computer and ensuring the correct audio output device is selected. The conversation highlights the need for proper configuration and understanding of the device connections to achieve the desired audio output.

FAQ

TL;DR: For this setup, 0 audio returns over HDMI from the Optoma 27HD; “HDMI connector on the projector is an HDMI input.” [Elektroda, superdeko, post #16725434]

Why it matters: If you feed the projector directly, your Denon AVR-2113 won’t get audio; route sources through the AVR first.

Who this is for: Anyone asking how to connect a Denon AVR-2113 to an Optoma 27HD (with Chromecast, PC, or phone) so sound plays on the receiver, not the projector.

Quick Facts

How do I wire Denon AVR-2113 to Optoma 27HD so the AVR plays sound?

Connect your sources to the AVR’s HDMI inputs. Run one HDMI cable from the AVR’s HDMI MONITOR OUT to the Optoma’s HDMI IN. Set your source to output audio over HDMI. This path gives picture on the projector and audio on the AVR. [Elektroda, Polon_us, post #16721318]

Does the Optoma 27HD send audio back to the AVR over HDMI (ARC)?

No. The Optoma 27HD’s HDMI is input-only, and users reported no ARC on its connectors or in the manual. Use the projector’s 3.5 mm audio-out only if you must extract analog stereo. [Elektroda, superdeko, post #16725649]

Which HDMI ports should I actually use?

Use the Denon’s HDMI MONITOR OUT to the projector’s HDMI IN. Use any Denon HDMI IN for your sources. Follow the clear OUT/IN labeling to avoid dead audio paths. [Elektroda, 1098678, post #16717405]

Why do I get video but no AVR sound when casting with Chromecast to the projector?

Because the projector is the only HDMI sink in that chain. Audio stays with the projector’s speakers. Route Chromecast into a Denon HDMI input so the AVR decodes audio, then pass video to the projector. “No need to pull the sound out of the projector.” [Elektroda, Polon_us, post #16725453]

Can HDMI from the projector carry sound to the AVR?

No. The projector’s HDMI is not an output. As one reply summarized: “HDMI connector on the projector is an HDMI input.” Use AVR-first routing for sound. [Elektroda, superdeko, post #16725434]

How should I set my laptop’s audio so it plays through the AVR over HDMI?

Open your OS sound settings while a movie plays. Set the default playback device to your HDMI/AVR. This avoids audio staying on laptop speakers and ensures the AVR receives the stream. [Elektroda, Polon_us, post #16721318]

What does the projector’s ‘audio out (jack)’ actually give me?

It outputs analog audio derived from the HDMI input, suitable for powered speakers or an AVR’s analog input. Expect stereo, not surround formats. It’s a fallback if you can’t route through the AVR. [Elektroda, superdeko, post #16721020]

I still have no sound—what quick checks should I run?

Confirm the source’s default audio device is HDMI/AVR. Select the correct HDMI input on the Denon. Try another HDMI cable/port. Keep the source → AVR → projector chain; bypassing it strands audio at the projector. [Elektroda, Polon_us, post #16721318]

Does the Optoma 27HD support ARC at all?

Users found no ARC labeling on the chassis or in the manual, so plan as if ARC is unsupported. Run sources into the Denon to handle audio properly. [Elektroda, superdeko, post #16725649]

How do I connect Chromecast so the AVR decodes audio?

  1. Plug Chromecast into a Denon AVR-2113 HDMI input.
  2. Connect Denon HDMI MONITOR OUT to Optoma 27HD HDMI IN.
  3. Select that HDMI input on the Denon; cast content. This yields AVR audio and projector video. [Elektroda, superdeko, post #16725434]

Why does everyone say not to “pull” audio from the projector?

Because the clean signal path is source → AVR for decoding, then video → projector. As one expert put it, “no need to ‘pull’ the sound out of the projector,” especially with wired connections. [Elektroda, Polon_us, post #16725453]

Will the projector’s audio-out give me surround sound on the Denon?

No. A 3.5 mm analog output carries two-channel audio. Connect sources to the AVR over HDMI to decode multichannel formats correctly and avoid quality loss. [Elektroda, superdeko, post #16721020]
