Can anyone verify they can get the HDMI Arc output from the monitor to send Dolby Digital or DTS to a receiver? I have it set to PCM out on the monitor and I'm using a good high-speed HDMI cable. The only audio out I can get is stereo. On "Auto" I get no sound output at all. The receiver works for sure with HDMI Arc input from other sources. Wondering if we need a firmware update, or maybe I have a bad unit? Thanks for your help!
