VPFET HDMI Audio Extractor Splitter 4K 3.5mm Adapter Converter with AUX RCA L or R Stereo Output Support 1080P 3D Compatable for PS4 Fire Stick Blu Ray Player etc

I wanted to be sure the box was passing the 5.1 signal correctly so ran test tones for each channel through my Bluray player's HDMI port. When the switch is set to 5.1CH the extractor's optical output appears to be discrete 5.1 channel Dolby Digital output just as you'd get directly out of of the player's optical out. When I switched it to 2CH, the output changed to stereo PCM with the 5.1 channels appearing to be encoded to Pro Logic but I can't be 100% sure if it was the extractor encoding them or the player without further testing. I will follow up with more later.My only complaint with this unit is you can feel the circuit board moving side to side when you unplug the HDMI cables. This was remedied by taking the cover off one side and putting a piece of double sided tape on the edge of the board to take up the slack. Overall nice quality unit and package, comes with almost everything you need to hook it up besides the 5V power supply.After using this over a year, I've found one possible issue. I have never seen it pass Pro Logic encoded stereo AC3. For example MAX seems to stream all audio AC3 out of the Roku but some of their content has only stereo L/R signal present in the 5.1. There should be a tag to tell my processor to Pro Logic decode the L/R channels but this never happens. It's possible that it could be an issue with the content's encoding, but since I've never seen this format come out of this box, I'd tend to think it's the box. I guess you could set the switch over to 2ch to resolve, so not a big deal. Another workaround would be to temporarily set the streaming device output to stereo only.UPDATE 5/31/25: I have used this little box for nearly 3 years but I am replacing it with a switcher that extracts audio. I could still recommend this unit, but at this point you probably want an extractor that is compatible with the ARC standard, as some current televisions don't provide an option to pass standard HDMI audio formats. Why this is?? idk, it's pretty stupid imo. But if you buy a TV that has ARC audio out only then this device won't work for you.

Why did you pick this product vs others?:Exactly what i needed and worked perfectly. The projector had only auxiliary output but Bose smart ultra needed optical input for Audio. Got this adapter and it works like a gem. Roku stick as HDMI input, Hdmi output goes to projector for video and Optical output goes to Bose. All works like a charm. Highly recommended, go for it if you have the same scenario as mine.

The setup was pretty easy, at first my Mac did not like the video output, it only showed HD. I was getting a bit upset. I went back and reconnected the box to my setup, I used a better HDMI cable and it seemed to have been the trick. Now the output video is 4K at 60hz and I was able to connect a soundbar w. subwoofer to my Mac.

Works, good audio quality (I use the stereo 3.5mm output).

I have a really good set of computer speakers with a subwoofer, and I wanted the sound from my Blu-ray player to go through them instead of the HDMI, but it doesn’t have RCA jacks, just the hdmi port. The converter does come with its own HDMI cable because you do need two, but not a separate aux cable! I plugged this in, plugged in the USB cable into a power source because it does need to be powered, and then plugged it into the aux port on my speakers, and the sound was great and matched perfectly with the video. keep in mind if you’re not using RCA jacks, you need your own aux cable because it doesn’t come with a separate two sided 3.5 mm jack cord!

This is exactly what I needed so I could still use my older AV receiver/ surround sound. I plugged my amazon firestick into it and then plugged red, yellow, and white cords in and hdmi output into tv....and presto...I could use my surround sound again!

Great Price. Use this with my Raspberry Pi5.

This HDMI audio extractor does what it's supposed to for the most part. It splits the audio signal from an HDMI source and gives you a few output options like optical, 3.5mm AUX, and coaxial, which is helpful if you’re connecting to older sound systems. Setup was straightforward, and it worked with devices like a game console and streaming stick without much trouble.The video passthrough supported 4K and 1080p just fine, and the audio came through clearly in most formats. The EDID settings are a nice feature if you know what you’re doing, though they might be a bit confusing for someone who isn't used to dealing with audio formats or signal settings.One thing to note is that it doesn’t seem to play well with every TV or receiver.I had to try a couple of different settings before getting the sound right, and occasionally had to restart devices to get it working again. It’s not completely plug-and-play in every situation.Overall, it’s a useful tool if you need to extract audio from an HDMI signal, especially for connecting to older audio gear. Just be ready to do a little trial and error depending on your setup.
