Question about outputs

I have a client bringing a WD TV live streaming box in and wants to hook it to a projector. I will need to use a DVI adapter which will make me loose the audio coming off of the HDMI. My question is, does the analog RCA audio output work while at the same time running the video out via HDMI? Or is is a one or the other type system?

Yes, it will work as long as you set the audio mode to Stereo.
