Hdmi for video and audio on RCA, possible?

hello people I am willing to purchase a monitor S23A550H, I want to connect to the WDTV via HDMI, but the problem is that the monitor has no audio output. WDTV will be possible to display the video hdmi - the RCA audio (red / white)?

Absolutely.   Just set the AUDIO Mode of the WD to “Stereo” and you’ll be fine.
