The first was the Mac Pro, where there is no SSID for the HD audio bus (see my patch for ALC885 Mac Pro - 12/15). Takashi, we may want to look into a function that uses the codec subsystem id as a fallback, with the PCI SSID taking precedence. We already detect the HD Audio bus, through the PCI ID.

as proc shows, but it's not used anywhere in the driver code.


This is the second time I've run into a system that has an HD audio chip, but doesn't have a unique PCI SSID. The first was the Mac Pro, where there is no SSID for the HD audio bus (see my patch for ALC885 Mac Pro - 12/15).

Takashi, we may want to look into a function that uses the codec subsystem id as a fallback, with the PCI SSID taking precedence.  We already detect the HD Audio bus, through the PCI ID.  Let me know.
