hi i have a laptop feeding video to my flat screen tv via hdmi. i want to use the mini jack port to feed the audio to my dj mi

Hi,

Yes that is possible, just right click on the speaker icon located on the lower right hand corner and select Playback Devices. Once opened right click on the device that you want to set as the default speaker or where the sound will be coming out. Click Apply then OK and that should do it. :)
