OREI 4K 60Hz 18G HDMI 2.0 Audio Converter Extractor - SPDIF + 3.5mm Output - HDCP 2.2 - Dolby Digital/DTS Passthrough CEC, HDR, Dolby Vision, HDR10 Support (HDA-912)

Great audio extractor everyone needs one or let me say every tech needs one. It’s made well. Feels great and does its job. It’s got two channel bitstream and TV settings optical 3.5 mm jack and an HDMI port you can’t go wrong.

Great for 4K setups. Currently using this between a Dish Joey 4 and a TCL 4K TV. It handles the 4K signal passthrough flawlessly while providing clean extracted audio. Simple to install and performs exactly as advertised.

Great build quality and works perfectly to extract bitstream audio from HDMI for optical SPDIF output. Sturdy connections and all-metal build. Only downside is that it requires external AC power to run.

Does what I wanted it for (hook the bluray player up to my stereo). Picture quality seems unchanged and the pass-through audio works well. There is however a slight audio delay between the stereo and the TV speakers. Not a showstopper; I just turn off the TV speakers.

My son loves the audio converter extractor and he gives it a thumbs up..

I am using it to split HDMI signal so that audio can be routed using digital audio cable. It works fine when it works, but after leaving it for a month or so in media room, I find it requiring power reset to get everything going. Without removing and putting the power back in, the projector never detected video signal. Not sure if the device I got is bad or it is just bad design with firmware issues.

I was using ARC on my Roku 65" TV but I had very noticeable audio lag when I output as anything but stereo audio. If I used optical, it minimized it a bit but it was still there. So I read some reviews and tried this much like how I used to have an A/V receiver to do the same thing. Basically, the HDMI output from the hub goes into this which strips out the audio that I send over to the 5.1 sound bar. Audio lag is completely unnoticeable now. This was always an issue with all TVs I ever had even going back about 10+ years on HDMI... it made playing games almost unbearable... but it made watching TV harder..... it wasn't until I hooked up an A/V receiver and then output that to the TV without the bitstream audio where the audio remained in sync. So this box does that same job and the sync is so well done. This saved me about $200 on buying another 4K receiver too to solve this problem. Now I need a larger HDMI hub since I'm running everything through this now and outputting the optical to my sound bar. ARC is very good... but the lag definitely is not. One thing is that sometimes I get an issue where the colorspace or something is off when I go from game mode with HDR back to regular.... the colors get all messed up. The solution is to put the HDMI hub and this device into an Alexa controlled plug (probably about $20 or less). Set up a routine so that when it happens that it cuts power to both the HDMI hub and this device and then turns it back on 3 seconds later. When you do that, it will fix the HDMI colorspace problem. Annoying? Yes, partially. But audio sync is a bigger one and with the Alexa routine, I don't have to get up when it happens.

I inserted this device between my AppleTV and my AV preprocessor, and fed the optical output to my Soncoz DAC. The DAC’s analog outputs go to the AV PrePro, and it sounds somewhat better than the AVR’s 8-year-old DACs. Audio quality was excellent, but I heard glitches or skips about every 10-20 minutes. I switched to a JTech HDMI audio extractor I bought a few years back that only supports 1080p. In 2 hours of listening to the JTech I didn’t hear any defects. I may have just had a bad unit.
