That's weird that it's taking so long. I've placed two separate orders directly from WiiM and they are getting here in 2 to 3 days.Not yet.
Are you running the beta release for Amazon HD on all 4 ?
There are quite a few bugs documented in WiiM thread.
I'm referring to Amazon UHD casting beta bugs specifically. That's really the only feature I'm interested in because there's nothing else that does this so far.
I'm okay with working out the bugs when I'm seeing an accurate sample rate. It takes all the other nonsense out of the equation. I'm also interested in Amazon casting. I just want a clean signal to my RMEs. ;-)
