Hi again

l have connected the Oppo. A53 to the Prime via mini jacks and get sound but not MQA.

l have a QGeeM USBC hub which l would like to think does the same job as the camera kit?

It allows me to connect my iPad to Meridian Prime, but, not MQA because of limitations of the iPad.

When l connect the A53 to the QGeeM and Prime and also further connect to a charger via USBC the single white light you mention does come on but no sound!

Regards
Colin
