I want to disable USB audio output(because my air mouse stop hdmi sound), but cannot find any way? It seems most of the tv box have Sound device manager, but in settings missing...
Settings, developer options, mutimedia contents, disable usb audio routing (may be a little different, my device language is italian, is a "good sense" translation)
I can not see this future in thread " New firmware v1.2.7 for ZIDOO X9S coming soon" Pls do not forgot!
