I have just installed Ubuntu 12.04 (Precise) and am using it on my TV. The HDMI sound doesn't work.
All I have installed is:
- The preinstalled codecs and other software,
- a KDE game called KsirK,
- and GIMP 2.8.
I am using a custom built computer, and a LG TV. My processor is Pentium(R) Dual-Core CPU E5200 @ 2.50GHz dual core, OS is 32-bit, and I have 1.7GB of ram (after having to remove one stick due to failure). I am also running Windows Xp on the computer.
