XZP cannot connect with PHA-1A portable amplifier

[Jours]

Hi all, 
I brought PHA-1A a year ago and it working fine on any smartphone/tablet.
Recently i brought Xperia XZ Premium and i cannot connect with PHA-1A,
XZP detect nothing if i connect the USB-C to USB micro-B (android port on PHA-1A),
if i connect the USB-C to normal USB (apple port on PHA-1A), it detect the connect but no sound output,no matter i select "transfer file" or use deive as MIDI.
Anyone can advice what cable should i get from sony store and what setting should i choose in order to make my PHA-1A work with Sony Xperia XZ Premium.

Thanks.

Nope, USB-C to USB-micro-B does not work.  You have to use a USB-micro-B to USB-A cable, and an adapter from USB-A to USB-C.
