I'm trying to use my wife's laptop to watch movies and TV Shows on my LCD TV.
I'm using a fresh install of Ubuntu 10.04 Lucid Lynx.
My wife always used the Windows Vista (came with laptop) to watch videos, but
the Windows Vista was not handling well (performance issues) the high
definition videos. So I convinced her to make a dual boot on laptop using
Ubuntu.
Laptop is D'ell Inspiron 1525 laptop and the TV is a Samsung LCD TV 26".
There is no audio when I plug the HDMI cable. I have tried a bunch of
attempts to configure the audio output (searching on Google), but none
of it works. Even when I try to run 'speaker-test' there is no audio at
all.
I'm very pleased if someone can help to figure out what is wrong.
