I don't have the issue with any other apps, but don't get any sound when running the HBO GO app. Current 113MO firmware on GT1 A912 box. Box hooked up to TV via HDMI cable. Thanks.
I tried the SD Card method and the box freezes on the opening "B" screen. I am going to order a USB "A" to USB "A" cable to try the USB method. Thanks.
HELP!!! i've done what you had suggested, and now I have NO SOUND AT ALL on anything! This is now totally useless to me! Came up with 793MO, Android 7.1.2 New Beelink logo and such.
