OCD is apparently a helpful prerequisite for using the HDMI input - as in noting the exact configuration that 'works', and hopefully being able to replicate it.
What's a PITA for me is that my default laptop configuration uses the Intel video driver, which works just fine with my external monitor when I have the laptop connected to the monitor(via DisplayPort/HDMI adaptor) and Bluetooth KB and mouse on our desk, where it's my home workstation to remote connect to the office.
To prepare for REW apps, I have to shut the laptop down, power up on battery, and select the Geoforce driver that contols HDMI audio by detecting it on the Screen Resolution menu on the desktop. Only then, after extending display, does Keith's connection sequence work. If I don't do that exact sequence, REW seems to ignore the UMM-6, and my laptop defaults to the Realtek speakers rather than the Denon, which shows as "unplugged". And as soon as that happens, Screen Resolution display defaults back to the mobile laptop.
As for HDMI audio, I wonder if part of the problem for people that aren't getting more than two channels is that apparently you need a video card in your laptop that has HDMI audio surround sound capability. Simply having HDMI connectivity by itself might not be helpful if the card doesn't support 7.1 audio, hence you only get two channels. I think I read on the Dell support forum that certain older laptops (pre-2010) which have ATI graphics cards with HDMI connectivity and stand-alone audio cards or motherboard drivers with suroround sound support need a special kind of cross-connection to enable HDMI audio. At least with Dell, the built-in Intel drivers don't support HDMI audio on the MB as such. In Jerry's case, with an AMD machine, who knows.
Good thing I'm not doing this every day.....Edited by sdrucker - 2/25/13 at 12:08pm
