well, I always had the issue both with fm radio and now with qradio.
First, how do you change the region? I haven't seen such a button in QRadio itself (0.2.0?), and since PR1.3 I don't see the /sys/class/.../region file at all. I can cd to the directory, but echo and touch all refuse to create file 'region' or to write anything to it.
Note: After I installed QRadio and opened it (no headphones inserted), espeak and media player went mute, and microphone went deaf (VU meter). Will have to reboot.
Any updates? Hehehe
