In my quest to discover which Linux distro would detect all hardware from a Live CD, amongst the several distro's I've downloaded was OpenSuse 11.2.
This worked from the Live CD, detected all my hardware including sound-card and correct screen resolution of 1366 x 786.
I did have to chose the vesa mode at the beginning of the boot screen but nevertheless it worked.
However, I'm more keener on using a debian based system, and have been looking at Linux Mint 8 again which from the Live CD detected correct screen resolution but was only able to hear sound using my external earphones plugged into headphone socket.
This suggests with a bit of tweaking I should be able to get sound configured.
And perhaps have a go at installing to hard drive with Win 7 dualboot
