Monitors speakers output Separation

[AMIRBSS]

HI
i have built in speakers in my monitor
when i play a movie\presantation all is well
when i disconnect vga cable their's no sound from the built in speakers - although audio cable is connected to the monitor.
how can i hear sound from built in speakers although vga is disconnected? i need it for another monitor.
i didn't found something in vga properties or monitor properties.

sounds like to me that when the VGA cable is removed the "no signal" state it goes into also stops audio output. If its designed this way i cant think of a work around.

A cheap set of pc speakers will cost you less than £10/$10
