I am really confused on where to start with this one. I installed Ubuntu 13.10 using Wubi with no hiccups. But I have been struggling for a lot of hours trying to find the right information to update the graphic drivers. It seem that i have to use the drivers included into the linux distro but the main driver does not output the sound through HDMI like i need to. I tried downloading drivers from AMD website but that lead to disaster blackscreen so i had to reinstall everything. So I tried an alternate drivers(additional drivers) in the distro and that worked for HDMI audio but video was choppy it seems that they are not the right drivers. Its shown as XPS 8300 . Where should I go from now? Any help would be appreciated. My comp config is intel quad core q8300, 3 gb ram and asus HD5450.
