If I turn off the TV it is connected to before the Chromebox sleeps, then I will have no audio when I resume. I had the same issue with an Intel Celeron 847 board I was using before this, and to fix it I had to add a script mentioned here:
http://openelec.tv/forum/68-audio/55789-oe-3-beta-2-no-sound-after-resume-from-suspend?start=53

This was with OpenElec 3.x, but I guess this problem persists in 4.x as well? I will try this and see if it fixes the audio.

my blacks were ok the problem was the banding which was clearly visible on the greyscale ramp test pattern.

I tried followed all of the instructions, but now my chromebox reboots with the following message:
"SeaBIOS (version rel-1.7.5-9-ge0678e9-20140709-MattDevo)

Booting from Hard Disk...

And there is nothing I can do except reboot it. I tried factory reset with the reset button, but it ignores it. I tried pressing ESC to get to the boot menu, tried pressing CTRL-D, and still nothing. Any suggestions?

Thanks!

Assume you ran the setup for a standalone, and are now trying to boot a USB stick to install your OS? Do you get the 'PRess ESC for boot menu' text before it tries to boot the internal HDD?

did you perform a factory reset before running the dual boot setup? Either way, you should still be able to boot to ChromeOS or use the recovery option

I'll need to hook back up to my Panny VT50 to confirm, but this isn't optimal on my Dell WFP-2408.

On it, the xrandr Full/Auto/Limited settings seemingly have no effect, and I get the following:

16-235 xbmc setting disabled: black clipping good (ref 16); greyscale ramp: stairstepping
16-235 xbmc setting enabled: black clipping incorrect and blacks extremely grey (ref 0); greyscale ramp: smooth

I'd like to have a bit better handle on this before I add it to the wiki
