no volume control for monitor?
Got a brandnew Mac mini (2.6 GHz) and connect via HDMI to an ASUS MX279H monitor. Sound is clearly transferred via HDMI, but can control volume only via monitor keys, wireless keyboard volumen controls a greyed-out. Tried also to use the head-phone output jack and change the sound controls, does not work. Any ideas ? Do I need to change the output to HDMI-to-VGA plus head-phone jack connection ? Thnx for any help.
Mac mini, OS X Mountain Lion (10.8.3)
