Help with Loop Hearing System

[Coby.]

My old man uses hearing aids and is really hard of hearing without them, we've dug out his old loop system and it works just fine on normal tv BUT as soon as you flick to HDMI to use our android streaming box the system doesn't work.

My brother ordered a digital to analog transfer box and connected the supplied cables, still no joy.

Anyone able to help?

Can take pics of all components if it helps as my description is poor.

@DannyR anything you have experience with??

Take a pic of what you've got mate. Induction loops is what I do :up:

Loop box

Digi to Analog Converter

Android Box

Back of TV

The TV is old as it's a temporary one and will be replaced with a new one soon if that plays any part?

Is that red loop current light constantly on?

Obviously if you're getting audio from it when watching normal TV, it's working ok and your issue is getting the audio out when on HDMI.

Is the digital output turned on in the TV menu? I know on mine it can be turned on/off

I take it when you switch to HDMI, you unplug the red/white RCA cables from the TV and plug them into your converter?

I'd probably hazard a guess that he convertor is being fed a non lpcm signal over the spdif (I.e Dolby digital, dts ) and that the box can't decode it.

Does the tv not have some other analog outputs as they would be the best way to feed it and you also won't get sync issues then either?

Turns out we're just dumb, presumed my brother had tried that as he tried a few things before I tried to help.

No worries mate. Any other problems with the loop side of things give me a PM :up:
