moe:~# lspci -v -s14.2
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
        Subsystem: Giga-byte Technology Device a002
        Flags: slow devsel, IRQ 16
        Memory at fe024000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Kernel modules: snd-hda-intel
