Does the onboard > audio PCI entry have no MSI support, right? Looks like it: $ grep snd /proc/interrupts 16: 108 109 107 106 106 108 107 118 IO-APIC-fasteoi snd_hda_intel 90: 3 3 4 4 4 4 3 3 PCI-MSI-edge snd_hda_intel Btw in alsamixer, I have a bunch of controls for the SB soundcard and when I select the HDMI sound card, it shows only one "S/PDIF" volume control which can only be muted. I'd guess this is the audio output over the monitor when it is connected over HDMI or so. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
