Is that the right driver? or should i have to use a higher version? Is it in the repo?
The video quality is sloppy/awful.
ANOTHER Problem:
It has 1 microphone jack and 2 headphone jacks. While the laptop speaker works fine, the moment i connect a headphone in either jacks, there
are no sound

I have tried each possible settings in alsamixer, kmix and systemsettings but have failed.
Systemsettings>Multimedia shows me these adevices
HDA Intel (STAC92xx Analog)
HD-Audio Generic, ATI HDMI (HDMI Audio Output)
When i test them only the 1st one work while the other dont.
I need these things sorted out as it makes my new lappy useless.
