I decided that it was the new phone's day for another attempt at USB audio out. It had not worked well for me with the lost-in-a-flood mi4i, so now for the Moto X Play (Marchmallow 6.0)...
At first, my experience with the X Play was much the same as with the m4i, except the GO V1 (450) worked, at least for a while, as did the little HiFiMeDIY thing.
I've been having trouble with this USB out on several devices, and slowly, the idea bloomed...
try a different OTG cable. Ha! Basic, eh? Well yeah...
And Moto Play X to Geek Out V1 450
just worked. Brilliant. But, drawing lots and lots of amps (heck, remember it has to heat the room as well as make sound!)
Time for the
Plugable 4-port Universal Charging Hub. It should certainly be able to produce the amps, although I have no clue how a DAC tells it how many. But
No Go... Device not recognised. Surely a hub should be transparent? if this thing works direct, it should work with the hub, shouldn't it? OK, probably the answers are in the 500-plus pages of this thread.
Anyway, it occurred to me to try the
Plugable with a thumb drive, which is pretty basic for a hub --- and I didn't see that on the phone. Then I get a question about
Allow device to access USB (paraphrased), and having confirmed, then thumb drives are visible on the phone.
Curious thing: plugged in the DAC again
and it just worked.
So, after some time, I'm back here on p.523 of the thread as a new beginner, with beginner's advice: If stuff doesn't work, try a different cable!
(And if other stuff doesn't work, hey... mess with it
)
