I'd really doubt that colour management is going to do anything for the green/black problem. Its for tweaking colour settings, not changing wrongly displayed colours.
As for sound, I dont know...The sound chip in your computer (RTL ALC883) should work with linux just fine out of the box. Playing with mixer settings cvan be nasty even if you know what you are doing, and ubuntu uses a different mixer to the distro I use (actually quite different sound software). It could be user error, or it could be some other problem. Sorry.

Maybe, maybe not. It would make things easier if you had of described your problem from the beginning (green replacing black), and given us any other information that could help, like "my TV which I have hooked up to my computer via (insert *VGA, DVI, HDMI, displayport, etc*) is detected wrongly".
BTW, if you are trying to get audio over HDMI, its posible that your chipset does not support it. I know that none of the intel video chipset support audio over HDMI (under linux at least) a few years ago.
Ubuntu versions having issues this soon after release is nothing new. *thinks* "this soon after release" is rendundant, ubuntu is known for having many long standing bugs.
Maybe try debian? Its not any harder than ubuntu, and its a lot more reliable with less silly bugs....
