I am playing music on a NW-WM1A through the walkman port using a WMC-NWH10 to a usb cable to a TA-ZH1ES USB-In and the NW-WM1A does not log the time it has been played in this configuration.
In the walkman settings menu it typically logs the total usage of the walkmans play time. It seems to work through the balanced or unbalanced headphone jack, but not in the configuration I have described.
Please update the walkman so it logs playtime through the walkman port on the bottom. Thanks.
