I have an M4A79XTD EVO..that's close. I'm using a Phenom II X4 I have Alsa installed and use it 'flawlessly' with the Asus Xonar D1 PCI audio card and the Alsa Mixer serves as the interface with the card. The module or driver or firmware whatever it's called for the Xonar D1 comes with the Kernel. -- CK Deo Soli Debianae, Invicto, Seculari
