When I first time launch my exe, not any headphone or other sound device is connected.Then I try to insert headphone, but no sound. I need to restart my exe. I guess it is because when fmod first init, it detect no device, then run on silent mode,even if I insert headphone later.
Maybe I can detect the headphone is connected and reinit fmod or other better way?
I already know it is about sound driver realtek.If I uninstall it, every thing is OK.
