    Does the "Blackbird 4K HDMI Audio Extractor, 18Gbps, HDCP 2.2" Product#24278 support down mixing 7.1 surround, Dolby TrueHD , DTS-HD, or other HD audio formats to Stereo, or will there just be no sound with the 2CH setting when such a source is used?
    Scott H on Aug 7, 2017
    BEST ANSWER: There will be no sound.
    Is an HDMI output connection required to receive audio at the analog and optical outputs? A couple of the other models have this feature.
    A shopper on Jul 12, 2018
    Has anyone tried this with Amazon Fire TV or Chromecast and had audio from the L/R output? Thanks.

    Question related to Blackbird 4K HDMI audio extractor (#24278). The switch in the Input section has three options TV, Bitstream and 2-CH. If I understand correctly setting to Bitstream, simply passes the bitstream to the output. Does setting to 2-CH decode the bit stream to 2 channels and sends to output ? What does setting to TV mean ? Thanks in advance for the answers
    Shivakumar G on Dec 31, 2017
    BEST ANSWER: From the manual: "TV/Bitstream/2CH Switch: Allows selection of the audio format. The TV option sets the audio output to that of the connected display. The Bitstream option passes the audio output from the video source device and the 2CH option sets audio to 2-channel stereo." There's no mention of up or down conversion; just straight pass-through.
    On the pamphlet that came with this, under specifications, it lists LPCM 5.1 under Optical Audio Formats. Is that a mistake, or has anyone been able to get that format to work? From what I've read on the internets, S/PDIF can't do LPCM 5.1, or any uncompressed surround formats.
    Ochuko K on May 21, 2018
    How's the audio latency? I bought a different extractor to connect between Apple TV 4k and my stereo (Sonos Play 5), but there's a noticeable audio delay.
    Franklin L on Apr 27, 2018
    BEST ANSWER: There isn't any. It's actually the reason I ended up with this one. Everything passes though with no issue. The only thing is if the source (like the apple TV) changes from 2CH to Surround, there is a 1 second pause of no audio (could also just be my older receiver).
    Will this output to both the optical out and headphone jack simultaneously or is it and either/or proposition?
    New User U on Jul 20, 2018
    BEST ANSWER: It’s either or not both. The audio signal is not stripped hoewever. This is not much of a limitation. Most people would want optical or headphones.
    Will this unit pass through the audio over the HDMI cable to the TV AND ALSO output the audio to the line out or optical jack? Or does it strip the audio from the HDMI output?
    Ron F on Jun 26, 2018
    BEST ANSWER: The unit does not strip the audio from the HDMI stream. It simply extracts the 5.1 audio stream and outputs it to the optical output OR extracts the stereo stream and outputs it to the analog mini jack.
    Is it ARC compatible? i.e., will it pass ARC from output through the input? Can it decode the ARC audio signal or just the signal on the input?
    James M on May 19, 2018
    BEST ANSWER: Not ARC compatible. Only decodes from the input side.
    Is this unit compatible with Dolby Digital Plus?
    A shopper on Jan 5, 2018
    BEST ANSWER: I can confirm the unit can extract Dolby Digital 5.1 (AC-3) from and Apple TV 4K unit via HDMI. I believe the Apple unit can output both AC-3 as well as E-AC-3 (7.1). I have no data on E-AC-3.
    Will this pass 7.1 from the Apple TV HDMI to my SPDIF-only receiver (which takes 7.1 of course)?
    A shopper on Dec 10, 2017
    BEST ANSWER: I haven't found any content on my Apple TV with 7.1, but it supports TrueHD which is usually 7.1. So I'm going to say yes.

    Work with Apple TV 4K
    I have an old audio receiver which doesn't have HDMI inputs. I used the Blackbird 4K Audio Extractor 18Gbps, HDCP 2.2 to extract the audio signal via optical to my older 5.1 Dolby Digital receiver, and I got the Dolby Digital working properly. My TV is a top end Panasonic 4K TV with supports HDR and has a full array local dimming (FALD) back-light. I tested it with my Panasonic 4K Blu-ray player and my new Apple TV 4K and it passes through the audio and video with Dolby Digital and 4K with HDR. In short it worked for me with 24fps and 60fps sources with 4K and HDR. Apple TV 4K and 4K Blu-ray worked great with it!

    Doesn't work great for the Nintendo Switch
    My primary reason for buying this was to get an optical audio out from my Nintendo Switch to my Astro A50 headset. That works in a very limited fashion. The Switch outputs its audio in LPCM 5.1 which is an uncompressed multichannel format. Apparently, that bandwidth is too great to support all the channels over an optical audio cable, so I only get left and right audio channels to my headset. Center channel and rear channels don't make it through, so using the headset means I miss out on some of the audio. Since this only provides passthrough audio, there's no conversion of LPCM to Dolby Digital or DTS (which are compressed formats that are supported by the bandwidth constraints of an optical audio cable). The fact that this device doesn't work for my case isn't its fault, but it would help if there was a chart on the description page that listed which audio formats could be successfully extracted. If you can't change your surround source audio to Dolby Digital 5.1 or DTS 5.1, then this device won't work for you.

    I have the HDMI out going from the Blackbird to my audio receiver, so the video and audio that comes out of this device over HDMI looks and sounds exactly the same as if I weren't using it, so it didn't break anything in my A/V setup.

    The HDMI In port on the device is mislabeled as "HDMI Out", so it appears as if there are two "HDMI Out" ports. The diagram in the instruction manual is correct, however, so use that to figure out which HDMI port is the input.

    This worked perfectly!!
    This solved my problem perfectly. I bought a new Apple 4K TV and was bummed that they took away the audio optical output. I have a great older Denon receiver that is not 4K compliant so I need to be able to go directly from the Apple 4K to the my Sony 4k TV to achieve 4:2:2 color space. Being able to extract out the audio from the HDMI output of the Apple 4K TV saved the day!! LOVE IT!!!!

    Not up to latest specs
    Works well enough but does not support Dolby Vision 4k 60hz Gamma 2.2 pass through from an Apple TV.

    Plays well with others!
    I had an install with about 20' of HDMI cable to an AV cabinet and another 30' to the projector. I needed to tap the HDMI audio and send it to an audio amplifier for the venue's speakers.

    I bought a this audio extractor to replace a different brand extractor that wouldn't work with the HDMI booster/amplifier that was in the AV cabinet. This Monoprice audio extractor worked perfectly with my existing HDMI booster/amplifier right out of the box.

    I also bought the Monoprice VGA to HDMI adapter for legacy laptops and all three boxes in my HDMI signal chain work fine.

    Love the fact that Monoprice actually has people to talk to if you have technical or application questions.

    Works perfectly
    My receiver passes audio to TV from HDMI but doesn't send it to the speakers. My Roku only has HDMI out. This box extracts the audio and sends it out an optical port, which I connect to my receiver. Worked perfectly the first time...

    Solved my problem.
    It did exactly what I wanted to do, split hdmi video/audio to hdmi video to tv and optical audio to Sound bar. No problem with picture and sound in sync.

    Works well
    Absolutely fantastic. We had a device where the audio out ceased to work, so we just intercepted the audio with this device. Worked like a charm!

    Great but one thing....
    Easy to setup, just plug and play. Really good audio quality to my active speakers. Well defined sound with big soundstage and clear bass. Everything is good but one thing, there is no volume knob or a way to control the volume of the sound. It is very loud even at the lowest volume on my active speakers built-in volume setting. Otherwise a great product!

    Good 4 the $$ but: latency issue.
    inexpensive plug & play solution, worked well overall BUT: noticeable latency issue thru 3.5mm output jack. running a Blu-ray movie to a monitor w/extracted audio routed thru room sound system receiver; audio thru room system lagged monitor sound enuff 2 notice. Good 4 the price, but I'll go to a (higher-priced) pro product as soon as I cn afford it.
