Hi Nightglow. Yes i have enabled both of those in the bios. The onboard sound installs and looks perfectly ok, but it just will not output sound.
Davefran, no originally i just moved the Xonar which didnt work, then i put it back and it worked fine. Uninstalled the drivers then moved it and reinstalled. The installation just hangs trying to find the card Move it back and reinstall, works perfect.
mmj_uk, whilst searching for my issues, i did find a few people with dead ethernet ports.
