sungod Posted September 22, 2019 Share Posted September 22, 2019 For sometime I have had an android box hooked up to the TV connected up through an HDMI port. I also have a home theater system which I mainly use for enhanced audio through an HDMI also. Its been working well for years. Recently I switched to AIS and they threw a play-box into the deal. What happens now is that there is no audio on the home theater when using my android box at all unless I turn the play-box on as well even though I am not watching it. I've tried plugging all devices into different HDMI ports, but the problem persists. Anyone else having this or knows of a fix? Thanks, Link to comment Share on other sites More sharing options...
Peterw42 Posted September 22, 2019 Share Posted September 22, 2019 Nowadays there are different HDMI ports on TVs, and variable settings. A standard HDMI is receiving A/V form a source, HDMI ARC (audio return channel) can be used to also send to a device. HDMI CEC allows control of other HDMI devices from one device etc. google HDMI ARC, HDMI CEC etc to learn the differences and applications. It should just be a case of playing around with ARC, CEC settings to nominate what video/audio goes to/from which device. Which device controls other devices, Audio button on TV remote may switch audio output etc (some television brands may have there own proprietary name for ARC/CEC) https://jtechdigital.zendesk.com/hc/en-us/articles/115002862853-ARC-Audio-Return-Channel-CEC-Consumer-Electronic-Control- Link to comment Share on other sites More sharing options...
