Apologies to all for me continuing to take this off topic. Thank you all for your replies. Thank you CombatWombat: it would be helpful to know if you see the same effect as me. To be a bit more clear on what I did: Plugging in the standard Roger cable (USB C male to TRS (two rubber ring) plug with nothing else connected (to the cable) causes the Roger ON to display the musical note streaming symbol. Connect a cable with USB C plug either end – and nothing else connected – and you don’t see the musical note symbol. Seeing as the Roger spec says its USB C port accepts digital AND analog inputs, I’d have expected Roger to have been happy with both cable types with USB C plugs. Hence I felt that Phonak would have gone non-standard with its cable so that Roger only detects streaming when a Phonak cable is connected. I now think this could only be achieved by Phonak incorporating a chip in the Roger cable. It’s worth noting that USB C cables, unlike earlier USB cable are not directional – so it’s not an in/out issue. Yes USB cables vary but only according to voltage AND current capacity (for rapid charging) and for different data rates but the cable wiring remains the same – the beauty of USB C. I guess the big question perhaps is “has anyone seen a USB C to USB C cable from Phonak that does work for streaming digital audio straight into Roger?”
