I've been helping Davy test their latest beta. Unless you have a version newer than yesterday's build, it still doesn't work via the HO (it plays, but re-samples everything via the Android OS to 48 kHz). The good news is they're aware of the issues and are working on it
I've had less success working with the folks from Tidal. They basically seem to be in denial and can't even give an indication of when they're ever going to support the V30 DAC (which they'll have to do, if MQA is ever going to work properly on their Android app). I've had even less luck with LG. I've filed numerous support requests about the 44->48 kHz upsampling and have had zero response.
