I am in the process of testing why it doesn't work with a cable attached to the 3.5mm socket. When I am listening over the Bluetooth, its just works, but when I plugg the cable, witch came along with my Purity Pro, the sound disappear.
When I tested another 3.5 mm cable with only 2, instead of 3 black markings on the plug, it all worked.
On the 920 it does work with the 3 marked original nokia cable. And I am running the same OS on both ( 8.10.14219.341)
Is it any difference in music quality between these two cables?
