My ASUS A8N-VM CSM motherboard has an on-board sound chip–the SoundMAX ADI AD1986A. Although sound does work reliably on Windows 7, I was a bit disappointed that neither ASUS nor the manufacturer of the sound chip offer drivers for it for Windows 7 (or Vista for that matter).
Among other things jack detection, output to front and rear jack simultaneously and surround sound are no longer available using Microsoft's default HD Audio driver under Windows 7.
Under Windows XP and several Linux distributions (Arch, Gentoo and Ubuntu) that I've tried everything works as it should.
Since I switch between headphones and speakers quite often, this annoyance begs me to ask: aside from buying a sound card, is there any way to get sound from both outputs at the same time?
