Powermac G4 Digital Audio is a special case. In general, older PPC Macs use snd-powermac and newer snd-aoa.
Newer machines have something called layout-id in their device-tree. This is where snd-powermac sets its limit, and it actually writes this to dmesg. snd-aoa contains a list of machines based on layout-id or device-id, and pretends to support Powermac G4 Digital Audio among others, but seems to fail in this. At least snd-powermac does it better. There are two other machines identified by their device-id, all the rest have a layout-id. Debian Installer tries to make a decision between the two drivers, and, either manually load snd-powermac and blacklist snd-aoa, or do nothing. > Should I file a bug or add this information to bug #650588?

Device-tree is a good source of such information: cat /proc/device-tree/machine cat /proc/device-tree/model find /proc/device-tree -name layout-id find /proc/device-tree -name device-id and: grep machine /proc/cpuinfo Risto -- To UNSUBSCRIBE, email to debian-powerpc-requ...@lists.debian.org with a subject of "unsubscribe".
