I have micromax canvas smart tv. It has 3 hdmi ports, one of which is hdmi arc port. Recently i have purchased Marq soundbar which also has hdmi arc TV port. But when i connect it to TV arc port no sound i hear from soundbar. Also there is no option in TV settings to switch off the tvspeakers or something else to make arc port on. Please help if anybody have any idea...
If you can change the audio output type to PCM stereo in the TV settings menu try that.
Make sure you have selector HDMI-ARC as the source on the soundbar.
Make sure that your HDMI cable is new enough to support ARC.
