I think I may be being a bit dumb here but I have the same problem - just upgraded to firmware 01.01.35
I remember previously having a sound option but I can’t find it again nor can I see an Europe or N America setting. Could you point me in right direction please ? Where do I find it ?
The options I have under Settings are - Equalizer, power, display, language, FM setting, system info, reset all, format, usb mode and press and hold.
