I followed the easy setup but no sound.
Im thinking its due to my older Sony TV (it works downstairs on a newer tv)
Any ideas on how to get sound?
If it works on one TV, but not another, might it be the HDMI connection on the older ATV is not passing sound? Check the settings on the TV to see if it can be adjusted.

Check the HDMI port settings on your older TV. If the TV has an HDMI 1.4 or earlier and the Android box has an HDMI 2.0, the issue is more than likely that the copy protection on the content is the issue. The easiest way to get around this is to use an AVR between the TV and the box. Some TV's though do allow you to set the HDMI port in the settings to the port type, which is why it is worth checking. You could also try changing the audio output settings on the Android box as well to see if that helps.
