sorry I don't do this often info on the box is
ATI Radeon, 512 MB/MO DDR2 , HD 3450, Full HD 1080p video playback with UVD/4 HDMI/TM with 5.1 surround audio Dual monitor support.
far as I know it's all up to date even ubuntu.
I have changed nothing since I got sound back and that was nearly a week ago. I hope what I posted is the right info you need.
thanks for responding.
