Does what it says.

I have HDMI distributed through my house so my media PC is seen in every room. Some setups are 5.1, others are 2.0 and won't reproduce the center channel if it is in use (older sets, mostly).I'm running Voicemeeter Banana on the PC, set to give 5.1 output on the HDMI and a downmixed 2.0 on the 3.5mm output, with the 3.5mm running to this embedder. This gives me surround sound where I have the speakers, and a faithful 2.0 where I don't.

Works Great

I only had a single use for this during a fundraising event. It worked perfectly but I doubt I will ever need it again. The venue had a combined sound and video system while I had a separate PowerPoint for video and another source for music (unrelated to each other but needed at the same time). This allowed me to run the music from one laptop and the PowerPoint from another. The audio feed from the PowerPoint computer was replaced by the audio from the laptop to do exactly what I needed.

I'll give it a good review but know this....

I'll give it a good review but know this: As several have pointed out, if there is no video on the HDMI input to this, it will insert audio and it will not put out audio on the HDMI out connector. People have commented on this in the questions area have indicated this; I'm just pointing it out. And you can't fake it with just plugging an HDMI cable into the input either. I think this should be made clearer in the product description.Also, one person gave it a bad review because using a microphone as an analog source gave low or no audio output on the HDMI. I think most people who would need something like this know that a microphone level input is MUCH lower in voltage than a line level signal which there was no sound using it like this.It does the job it claims to do, it just doesn't do everything that some people may want it to.

Does what description says with no frills

This box will replace audio embedded into an HDMI cable. There is a 3 position switch to select incoming HDMI, TOSLINK, or analog PCM from RCA cables. HDMI loops through this box with replacement audio multiplexed into the output. There are no frills. This means no fading, no stream protection while switching sources. You will probably get objectionable noise if you fiddle with the box with volume up. So don't. Turn the amplifier down then switch sources. All kinds of uses for this kind of item. Adjusting levels, fixing lip sync, adding sound to a silent source, all using other optional analog devices. This will not fix these issues by itself but allows a "side-chain" to be introduced . It is not a Dolby AC3 encoder but can pass it and can encode stereo PCM. This could solve many "no sound" issues while using HDMI as audio source. I only wish that it had level controls or at least a 10dB pad. At this price level it seems appropriate.Solved our problems. Happy with our purchase.

This device just works, perfectly

I used this to embed a modified audio stream into the HDMI feed of a cinema projector in a commercial movie theater with a 100ft screen. This was done so I could control and mix the audio that was presented via the theater audio system. The image on the screen was excellent as was the sound in the theater. I used it in conjunction with a J-Tech HDMI audio stripper to access the original audio. The audio stripper was run into a mixer and the output of the mixer went to the embedder. The HDMI video was passed from the source device to the stripper then to the embedder then to the projector. The whole system performed flawlessly.
