I'm using the Jetstream AndroidTV box and trying a trial of Nitro IPTV. But the issue I'm having is when I change to volume using the remote it shows the box volume changing but doesn't change the IPTV client (in this case ZalTV) volume. I know some of the Chinese Android boxes (one I have runs official AndroidTV) that just run modified Android have a different volume buttons on the remote. What can I can?
This isn't the place to get this sort of help, sorry. Your best bet is to check maybe freaktab as they deal with Chinese boxes and some users there might have an idea, or maybe even a fixed Android rom that you could flash onto your box.
