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.
