Problems with Air 3

[KenH]

No audio or almost no audio. Shows signal strength -65 dBA or lower. My conclusion is that the Devialet would benefit from a proper antenna, since it's casing is built like a "by the book" perfect RF shield. My TV is almost twice as far away from the router and two more walls in between, and it still streams 4k video content perfectly from the same router that won't stream audio with the lowest settings, to my Devialet. Also, the D400 costs almost 10x more than my TV and I think it should perform better in this aspect...
But I'm moving to a new apartment fairly soon, so I'll try to sort it out then, but I felt I needed to complain a bit about this flaw
