For those with the Live TV streaming drop-outs on Fire TV sticks - fixes and work arounds are noted here: PLex app very unstable running in the Amazon Firestick
That is not a fix for the Fire Stick 4k. It has already been discussed in this thread and causes major audio sync problems on SD channels.
See my other bug report about it here:
@jg121212 I have watched an SD channel for over 30 minutes in my testing and I have not yet seen the audio sync problems. From what I know, I suspect that with transcode turned off, all but the best wifi connections might manifest lip sync issues to which you refer. I suspect that the reason I am not seeing these issues is because I have a ceiling mounted Unifi AP AC Pro within 15 feet of both 4k Fire TV Sticks. I am using the new Silicon Dust HDHomeRun 4k ATSC 3.0 tuner on my network. My HDHomeRun tuner and my set-top devices like the Fire TV 4k sticks, Rokuās, and smart TVs all run on a dedicated VLAN.
Nah. I see the same problem, and Iāve tried with both gigabit wired, and unifi wireless. Some SD are much worse than others

make sure you turn on automatic adjustment, otherwise yes you get screwed up SD
I had automatic adjustment on previously but thanks. After several hours of testing, I can say that live TV is rock solid now and does not bail out to the guide as it used to.
For the others here, be sure you are running Plex Fire TV 4k client v8.10.0.21911 (9219e3c2). I believe that the stability is due to disabling Transcode Interlaced Live TV, with automatic adjustment on and also this version. Iāve never had it work consistenly till now.
Nope. Just tried the automatically adjust video quality on fire stick 4k v8.10.0.21911 with transcode interlaced off and the audio is still way out of sync. I was hoping your idea would work. We will have to wait for Plex to work on a real fix.
For some reason, this has been a thorn in the side of Fire TV 4k users for awhile. Live TV behaves on my Roku and also on my Samsung TV Plex client. I really like using my Fire TV 4k stick as my primary device. I am just not sure that we have the attention of the plex developers.
On a side note, I was really hoping there would be an updated Fire TV 4k device that would have a native gigabit ethernet connection and at least 16GB of memory instead of the paltry 8GB of which we get barely 5GB and with a dozen apps installed I am at usually 400MB free. Iāve tried doing the external storage thing, but it is not stable at all.

All of those things would be great. Iām currently watching live tv on my Samsung Plex app. It is rock solid. My other two tvs are not smart and both have Fire stick 4ks. Everything is great on them other than Plex live tv.
I also tried vmsmanās suggestions and had no success.
Iām running a firestick 4k with ethernet adapter. I have 4 sets of these and all behave the same with this version of Plex.
The auto adjust was a great suggestion. Iāve been using the bit rate selection in the bottom menu, and auto option never seemed to work. I see it settled on 1.6mb on a remote server LiveTV stream.
An interesting aside, I was running a wired ethernet adapter on one of my Fire 4k sticks. Realize that the USB interface on the Fire 4k is USB 2.0. That means the fastest you can expect is 480 mbps. In reality, since itās a half duplex data rate, you will see a peak rate closer to 180-240. I eventually changed back to wireless and I actually got a better data rate.
The Amazon branded ethernet adapter is only 10/100 anyway. I guess because theyāre cheap 
Agreed. However, if you bought a USB 3.0 ethernet adapter for the Fire Stick 4k, it would not help the speed since the Fire Stick 4k USB interface is USB 2.0 and that is only a 480mbit bus.
I did not mean to say that it worked flawlessly for everyone. There are many intervening factors that can and will work against this functioning correctly until Plex Development addresses how live TV is played on the Fire TV 4k stick.
My whole purpose of hosting this discussion was to get a lot of people to confirm that this is a problem and that I am not the only one having this problem. Until the Plex Devs see and then act on this discussion, it is just a discussion.
Yes I agree we need to get back on topic.
Just to reiterate, the issue appears to be random. From minutes to hours between the issue where video bombs out to the guide.
I was watching and looking at the console when watching LiveTV&DVR video from my home server (Haupauge internal card) and noticed an interesting message.
These messages appeared before my video stream bombed out to the guide. One time it was within a minute, 2nd time it was over a 2minites after these messages.

Hope this sparks some interest or memory of the issue at Plex.
Found that I had subtitles forced on so it was still transcoding. Missed it because subtitles werenāt actually showing up but the setting was on so causing transcoding and resulting in the crash/exit. The workaround is tolerable for me now until fixed.
Another workaround: PLex app very unstable running in the Amazon Firestick
(more reliable than flipping from HD to SD)
Still not a fix, and a PITA tho.
This is so frustrating because itās a Fire TV and Plex Client issue. I was able to dig up an old Roku and there are no crashes. Please address this because I donāt want to have to ditch my Firestick. Many of us prefer it to Roku.
Yes I see this too. The issue is discussed here:
