Our knowledgeable Technical Support staff would be more than happy to assist. Thank you
Audio turns off when you plug in Video Input. I tried several computers.
The Analog Audio works only when the Input to the TV is not plugged in, as soon as I plug in the Video Input Audio goes away but picture is good.
Sources tried MAC pro and Mackbook pro Laptop. I tired different resolutions
If I plug in an Apple TV then the analog audio passes via HDMI with Video
If I use a video monitor with Speakers all works as expected
I also tried a Monoprice Dr HDMI that inserts EDID info..No luck
This product is Identical to several other manufactures (Re-Branded) I found review with same issue
CONS: Dosen't seem to work with Computer Video source and Audio
PROS: Allows a problematic C61-K DirecTV box with non-backwards compatible HDMI audio to reinsert a good audio source (optical from the C61K itself in my case) and produce much more durable HDMI output that works with an older Onkyo 1080p receiver and a Samsung TV that balked with the original DirecTV C61K HDMI output. No more audio drops!
CONS: When I tried using the device in passthrough mode, I noticed a slight lipsync issue. So it must be massaging the original source to some extent. But I have a feeling people aren't buying this for passthrough mode....
in my case I picked this up to insert the audio from my laptop with the DP video, as I have an older 2nd generation unibody MacBook Pro ( mini display port HDMI adapter ). I also have a MonoPrice USB video adapter PID 6038 that doesn't output audio that I thought I could use this with on Windows and Mac computers that don't support DVI or HDMI. I figured after recently acquiring a MacBook air that only had VGA and DVI this would be more universal than the DisplayPort only adapter PID 6331/ 5969, and no lag like USB adapters in some cases.
however the only way I can get a TV to accept an audio signal is if I use a computer that supports audio over HDMI. a.k.a. the computer I don't have and that I had to borrow to test. but if I'm doing that then the computer already can output audio over HDMI which defeats even having this device in the signal chain.
Unless you need to re-encode the audio being sent out from a STB device or coming in from an analog source back into the video chain.
I only tested under 1080P. as I will most likely not run anything other than 1080P / 720P / 1080i in that order if the device supports it.
I was able on both TVs to get an audio source to play on the TVs with a blue screen and no HDMI input ( blue screen generated internally from this device In a 4:3 format with black bars).
so my options are.
#1. to get the DVI version of this PID 8124, and then not be able to take advantage of the optical output of my good computer. and require a HDMI to DVI adapter and minijack to RCA cable. the most compatible and cheapest option albeit it's going to be a mess of adapters ( micro-DVI, mini-DP-HDMI or USB-DVI to DVI-HDMI to HDMI to HDMI-DVI to DVI&Audio-HDMI ).
#2. get the DisplayPort version PID 6331/ 5969 and only be able to use it on my good computer.
#3. get a USB to HDMI adapter that supports audio PID 8079 and lose all of my USB ports on the MacBook air or lose one of my USB ports on the MacBook Pro. ( can't use USB hub without loss of bandwidth apart from a mouse and keyboard which is not needed on a laptop. those USB display adapters suck down most of the USB 2.0 bandwidth and I don't have USB 3.0/3.1/C). the simplest of the 3 options.
my 1st impression is that it does not generate an internal audio sync signal and is piggybacking the audio sync from the HDMI input and intercepting and inlaying its own data on the output. and if that's the case it will be useless for any device that does not output a fake or valid HDMI audio channel.
So to return / exchange or not to return / exchange, that is the question?
if I could expect a firmware update I would keep it, but if not I have absolutely no use for it ( and I even have DirecTV). the overall quality and construction is awesome but……………..
this order has been a nightmare since Memorial Day…………………………………………….

I highly recommend this inserter. It works exactly as advertised. By the way, Monoprice, you rock!

The only issue I have is every few days the TV will sync, but have a black screen with no audio or video. Power cycling this box fixes the issue, but that's annoying. However, that's less annoying than the C61K audio drops, and may be solved with a timer, or remote controlled power strip.
Every thing works perfectly. To eliminate manual switching, i am using a wemo power plug for the audio inserter and controling it with my echo/alexis
