2018 - Amazon Fire TV Stick 4K
Does this device support 4h UHD HDR content playback in Kodi and also audio passthrough (including Dolby Atmos and DTS-X)? I've seen that using a ethernet adapter is desirable, but is there someone using it with an AC router that is close to it?

See first post. Audio passthrough is DD/DD+/DTS only. If it's close to an uncongested WiFi access point, you don't need ethernet.

Thank you! Is there any device that is able to reproduce 4K HDR/HDR10+/Dolby Vision and still do Atmos/DTS-X passthrough using Kodi?

Good news: Well it would seem that the dreaded h264 interlaced bug may well have been fixed, according to this thread:
https://github.com/amzn/exoplayer-amazon-port/issues/81

Bad news: Fix won't be available until mid Q2, not sure exactly when that is, hopefully not long.
Will mean i'll finally be able to use my Firestick 4K for Live TV at long last, which is good.

Dear @wrxtasy,

can you tell me your sources, where I can buy that UGreen USB3-Adapter in a cheaper way?

Kind Regards,

One bug still remains somehow, although they seemed to work on it (unsuccessfully): if the Stick is connected to an AVR the Auto refresh rate setting is not working after a reboot of the Stick. Though something changed since 6.2.6.0: the Auto refresh rate setting keeps being activated (cosmetically) in the settings, but without functioning. You need to change the Resolution manually in settings and change back to "Auto" for enabling auto refresh rate feature into a functioning state again.

Is there any bugtracker or forum where Amazon Devs will read and where to report this annoying issue? Makes the whole stick worthless for me Sad Amazon knows for sure why they closed their forums... Sad

For what it's worth I found this charmingly named QacQoc UBS/ethernet hub works fine and is a little cheaper (in UK) than either of the options mentioned in the OP

Is everyone else having audio sync issues with this stick?

I'm setting one up for a friend. I've been a long time user of the first and second generation Fire TV's. Not at all impressed with this iteration, so far.

Netflix, Youtube, etc are fine, but nearly every video file I've tried in Kodi has required an audio offset. Typically, that's .05s, but VP9 encodes are more than double that. Nothing I've tried - (FireOS set to Stereo, Kodi set to Stereo, various permutations of frame rate switching) has made any difference whatsoever.

Meanwhile, the same files, played using Android TV Kodi, on the same Sony 4K TV have no such sync issues.

Anyone have any tips?

I haven't had this problem.

The FireTV 4K does weird things with stereo - it transcodes to DD/DD+. That must add some delay so maybe it's related to your problem (just speculating). You can avoid that by setting Kodi to "fixed" 5.1 instead of "optimized".

Tried various combinations of Stereo/Dolby on both Kodi and the stick. Also passthrough. Had no noticeable effect. TV is being output to a stereo, btw.

Wondering if I might have faulty hardware or whether everyone is experiencing it?

Just to clarify, I need one of these, and one of those micro usb splitter things.
What network speed would this achieve?

Not even certain if that is good.  It plays UHD 4k un-transcodeed h.265 (some are close to trouble-free.. a few have problems)

Those look about right for USB 3.0 GigE adaptors plugged into a USB 2.0 device (like the Fire TVs are)   They should deliver the network connectivity required to play high bitrate UHD Blu-ray rips (and that's the solution used by Vero 4K users to mitigate the 100Mbs internal network adaptor).  It's not a guarantee that a device will play these high bitrate rips though, as there may be other issues.

Cool, the bottleneck here is, I presume the usb2 controller?
Out of interest, how do u manage to run iperf3 on the Firestick?
Edit:, don't worry, ive found the instructions earlier in the thread.

I get around 280mb/s over WiFi. But the WiFi router is right next to the FireTV stick, so that's a best case scenario.
