Hi Fritsch. Do you mean that the audio mapping for the channels is now correct? That means the rear channels work correctly when on 7.1pcm audio?

Also, I'm using the UGREEN gigabit adapter with an otg cable. Is it true that the Firestick 4k is still limited to 100mbps even in this case? 

From my understanding you won't get gigabit speeds due to the usb2 bottleneck.
Should get way above 100Mb/s though, closer to 480Mb/s theoretically.

I could be wrong, i'm sure someone will correct me if so. 

Thank you for the reply. I don't understand why my question got ignored three times, but oh well. I can't seem to get a decent speed above 100 or so mbps when using it, so that's why I was wondering. 

Just to be clear, are you plugged straight from the firestick into a router/switch?
