This is a bit more tricky. I'm checking on resume what the status of Road Runner is but it is always telling me that it is in STOP state. What I do is wait a second and issue a STOP so it will not continue to play. But radio should only start again when in the radio skin. Will take another look.On resume sometimes the radio and audio start at the same time.
In my skin I issue a "radio_mute||EXIT||RESUME" when I leave the radio skin. When starting the radio skin I issue a "LOAD;ICE_RADIO.skin||PAUSE||radio_unmute" which pauses audio and unmutes the radio.
See previous response. It's working fine that way.And finally, if I don't have audio playing and I start the radio, it starts moth.
If you still have an issue let me know.
