. If the browser doesn't support suspending or resuming the audio context, the problem is with the browser, not C2 - C2 will use these to optimise battery life if they are available, but if they're not available there's not much choice other than to leave the context running idle in the background.
I will ask on tizen forum about browser and supporting Audio suspend.
But I must add - that when suspend work - sound or music doesn't work
when Resume - then it works again.
I chek my music app in Emulator for GearS2 S3 ... and logs shown that Media suspend works....
That time the music file is playing ( folder Music)
I need add this about tizen browser - I have NO such problem with another Tizen device ( Geas S, Mobile Tizen Z devices).
So... It is pitty, but i must use background mode..
