Inc CMI8788 [Oxygen HD Audio]" is already supported on FreeBSD, but this sound
card has something special : it's not a native PCI-E sound card, but a native
PCI one, so it uses the "PCI bridge: PLX Technology, Inc. PEX8112 x1 Lane PCI
Express-to-PCI Bridge (rev aa)" as a bridge to communicate with the
motherboard. And THIS component isn't supported!
No, that wouldn't matter. Bridges are fairly standard. It would be helpful
to get pciconf -l output so we could see the actual device and vendor ID
register values.
