In this specific test I was not trying to downscale. I was just trying to get a passthrough working to observe how clean the Linker was in a non-scaled use case. I was feeding a 1080p60 stream into the linker from an AppleTV and sending a 1080p60 stream to the projector. This is using a non-4k AppleTV so the best it can output is 1080p60. My Oppo Blu-Ray has the same limits. For what it's worth, I also tried this with my Tivo Bolt+ and Xbox One S at 2160p60 (UHD-1) using different EDID settings and observed the same noise.
Cable length between the AppleTV and Linker is 1m. Cable length between the Linker and Projector is ~12m. This gave me an idea to try the Linker in pass-through with my TV rather than the projector using a shorter cable. With this test I used the same cable between the ATV and the Linker, but I used a 2m cable between the Linker and the TV. So with two new variables, the TV and cable, the image looked much better with no visible noise. In both a pass through and up scaled use case, the image looked good. So this points to either the long cable from my component rack to the projector or the projector itself. With the same cable and projector plugged directly into the AppleTV the resulting image looks fine so I'm suspecting this is an issue with the output drivers on the Linker dealing with a 12m+ cable length. Keep in mind this is not a 2160p60 stream, but a 1080p60 stream and I've never had an issue with this cable run in the past.
Unfortunately, I do not have another long HDMI cable and my projector is mounted to the ceiling at the back of the room so experimenting with a new cable would be problematic at this time. I've been meaning to install a fiber optic HDMI cable in the near future prior to upgrading my projector to 4k, but I'm waiting for the new Sony 4k projector (VPL-VW285ES) to be released so I have some time.
My next test will be to put a distribution amplifier in-line between the Linker and projector to see if it makes a difference.
Well, the best/easiest would be to insert Linker AFTER the 12m cable, right before the PJ.

I put the linker between the X6300H and Epson and set it to preset 3.
(Set 4k30/4k60 presets for a 4K30 deepcolor PJ at 300MHz (e.g Wired UB/TW Epson)
[4k30 8/10/12 -> 4k30 422 12 300, 4k60 600MHz -> 4k60 420 300MHz])
The picture comes through fine...although the Panny BluRay says my "screen" doesn't supper 4K/60hz. But, worst of all, the receiver no longer plays the audio!
I've played around with the Linker GUI --- but since I don't really know what I'm doing, nothing has restored audio.
Could someone knowledgeable tell me what I'm doing wrong or at least kick me in the right direction.
Please post link to usermanual of X6300H in PDF, also confirm length of HDMI cable in your setup.
If you had run GUI, please confirm the FW version you are using.
If you messed with settings and not sure what you did, simply factory reset unit.
Basically for your setup, you should do the following, EDID slide on Custom, SCALE slide on DOWNSCALE, use quick preset 3 (HOLD RST + press INP 3 times) and you are done.
Lastly, i'm not sure how could a device connected at the output of your AVR have anything to do with the ability of your AVR to play audio from the sources connected to it. Do you have one AVR output in use or more ?
