There is a USB DAC function. This is using the DAP USB C as an input. There is no mention in the manual of using the USB C as an Output, so I do not think this is possible.I will have the nw-A306 in few days- does anybody know / tested if it supports SPDIF (coaxial & digital) audio output from USB-C ? Like the Hiby R6 III does with CR-06 dock. Couldn’t find anything on Sony 306 specs about it.
