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?
