iArkPower 3 Port 4K@60Hz HDMI Switch with Optical SPDIF & RCA L/R Audio Out, 3 in 1 Out HDMI Audio Extractor Splitter with Remote, Supports 4Kx2K, 18Gbps, UHD, HDR, ARC

I've started using my Roku for streaming FLAC audio, and needed a way to route the HDMI audio to an optical S/PDIF connection. This box worked well. There's no visible effect to the video stream. Audio works perfectly and it's especially nice that the box has a selector switch for 5.1 vs. 2 channel audio. I bought this 4k/60 Hz version rather than the slightly less expensive 4k/30 Hz version as future-proofing in case I upgrade my TV someday.Another reason that I bought this particular device was the IR remote control. Turns out it's already in Logitech's Harmony database. Just enter the switcher's model number -- HDSW00017M1 -- in the My Harmony app (shows up as "FiveHome" there rather than "iArkTech") and you can control it from the Harmony right away.

Audio port is damaged. The cable keeps falling out. The sound gets disconnected.

I plugged 3 HDMI inputs in from my set-top cable box, my Blu-ray player and my laptop. I connected the output to my 4K Samsung TV. Everything works great. Picture from all 3. Sound from all 3 on my TV via HDMI and through the RCA jacks to my stereo amplifier. All perfect. But when I use the remote to switch away from the Blu-ray player and then come back, or if I plug my laptop in and it switches automatically to it and I switch back to the Blu-ray player, the color is all screwed up from my Blu-ray player. I still get a picture, but it is purple/pink toned and the sound over both the HDMI cable to the TV and the RCA analog signals are both dead. The set-top box and laptop continue working, but the Blu-ray player doesn't. If I plug the Blu-Ray player back to the TV, it works fine. Then I plug it back into the switcher and it works fine. Then I switch signals and I'm back to purple with no sound. It is just unstable. I keep having to unplug things and plug them back in, and then it works for a while, and stops again. There doesn't seem to be any tech support contact information in the instructions. If I don't get a response to this review within a few days I will have to return it to Amazon. It's a shame, because otherwise this seems like a great product.

I bought this because I was adding PS4 to my existing set up with BlueRay/DVD player and AppleTV and didn't want to upgrade my receiver to get pass through. Previously I just used different HDMI jacks on the TV. I though this wold be an elegant solution and it has been except it takes 4 and half minutes for the box to pick up and transmit my PS4. Why, I don't know. The DVD player shows up immediately but not the PS4 or the Apple TV. So I left the Apple TV on the TV HDMI and I just patiently wait for the PS4 to show up which it does with a few screen flickers but then solid. I always set the switch and don't wait for automatic detection. It's almost as if the circuit is warming up but maybe I'm projecting this idea. It may be that I have a defective unit. Eventually I'll contact customer service and if the problem is solved I'll change the review to 5 stars. Regarding Apple TV I haven't yet bothered to see if it too will eventually be recognized by the switch. I'm generally too impatient to want to wait and thought it best just to leave on the TV HDMI. Too bad because this does seem like a well made product and is an elegant solution to those who don't need or want a new pass through receiver.

I bought this to essentially extend the life of my existing TV and Audio receiver. For that purpose this device works very well. I only run 1 HDMI cable to my Samsung TV and use the digital audio outputs of the iark device to connect to the digital audio input on my Yamaha RXV2400 receiver. I have a Roku box and a Samsung BlueRay player connected to the iark and I pretty much don't have to worry about it. It automatically switches inputs based on the device and sends the appropriate sound to the receiver. Now, unless I listen to the radio, my receiver pretty much stays on the same input setting for anything that is displaying on the TV.The pros are that the digital audio is passed and the receiver accepts that and auto switches to the appropriate sound mode. The only exception to this are movies in Netflix where, despite them saying the move is in dolby surround, the receiver isn't recognizing that. From reading other articles this seems to be a Netflix issue versus this device.Otherwise, if you have older equipment that still works well and are looking for a low cost solution, this works great.

First what I don't like. I don't like the design choice and color but who cares when it works. EDID works as advertised I think I get a little more punch out of optical 5.1 Dolby Digital with this switch. My setup is Nintendo Switch, Nvidia GTX 1070Ti and a PS4 Pro connected via HDMI audio extracted to optical using Creative X7 portable amp. Now it support pass or 7.1 but beware optical can't handle the bandwidth. So 5.1 Dolby Digital is fine with me. Both PS4 Pro and Nintendo Switch works flawlessly. The Nintendo Switch you need to set the sound to Auto. PC is another beast on it's own since Nvidia won't give me any control over audio output. I've tried everything so far. The EDID for iArkPower 3 just can't override the stereo speakers detected by my Dell 2715H. Only thing I'd like would be 5 ports and IR extended cable. Overall great product.

This switch is great and very inexpensive for the amount of function it has. I have a 20 year old Denon receiver with 5.1 Dolby. It uses sdif optical audio. I also use standar RCA outputs to feed audio to a 20 year old intercom system to play music from the Directv satellite music. I have a Directv r54, roku4 and new Apple TV 4K. It seemlessly switches using the remote. I programmed the switch into my old Phillips IR remote and I do not use ARC. It works great and is one of the few true HDCP 2.2 and HDMI 2.0 HDR switches. So far so good. Works great!! I highly recommend this switch. It also saved me from unnecessarily having to buy a new receiver.
