[Solved] Emulator doesn't support headphones?

[vsub_]

Works fine here.
When I unplug the headphones,the audio is sended to the monitor(with speakers)by using the hdmi and when I connect the headphones,the audio is played by my audio card.
I had similar problem before and I fix it by changing some option is the bios(I had to change the playback device manually otherwise every time I want to hear a sound from the monitor\headphones)
