Closed captioning issue on Onn 4k streaming box

[saturnaqua 4]

Hi, not sure if this is a problem with the streaming device or not. I picked up the new Onn Google TV 4k streaming box Walmart updated for this year. Initially I installed Emby from the play store so it looks like it's the Android TV version. I have some live tv recordings captured by my Hauppauge tuners. If I attempt to watch a recording and then turn on closed captioning it gives an error saying (I think) it couldn't load it. I tried sideloading the Emby for Android apk and it also does not seem to show the closed captioning (but it doesn't throw an error either).

I do know that it works on other devices as I can watch the same recording on Emby for FireTV and I can see the closed captioning.

Not sure what you might need as when I check the stats for nerds it shows it's direct play, so I don't think it's the server side.

Nevermind. Problem seemed to fix itself when I uninstalled the sideloaded version of Emby and went back to the android tv version. Very strange and as I have two Onn boxes, I was able to reproduce this (fresh out of box Onn, first install of Emby for Android TV 2.0.83g, closed captions don't work, but uninstall and re-install right away then closed captions work). Not sure why the Emby for Android doesn't seem to work, but since I use streaming boxes, I'm fine with the Android TV versions.

Hi.  That seems very odd.  Had you changed any settings?

No, it was basically, pull streaming box out of cardboard box, plug it in, let it install it's system update/set up and log into my google account. Once it was ready for me to actually use the box, first thing I did was install Emby from the play store (so the Android TV version). CC did not work. Friend suggested trying the android app, so I uninstalled it, sideloaded the android app, still no CC. Decided to give up and remove the sideloaded version and go back to the one from the play store and magically CC worked. I thought this was real strange, so I pulled my second Onn box out, let it get set up and installed Emby from the play store. Again, CC did not work, but thought, well, the second install seemed to make it work, so uninstalled and reinstalled from play store and CC works.

Now the first box, I did try fiddling with some Android TV system settings, but didn't make any difference. The second box was just straight up initial setup and immediate install Emby, check CC doesn't show anything and then uninstall/reinstall, so I never messed with anything on the second box.
