This is very much similar to bug #146357. system-config-soundcard-1.2.11-2 is the package in question. [root@mini ~]# kudzu -p -c AUDIO - class: AUDIO bus: MACIO detached: 0 driver: snd-powermac desc: "Apple Computer Inc.|PowerMac Sound" The device does emit sound, its well detected by alsa, so something like: aplay /usr/lib/openoffice.org1.9.100/share/gallery/sounds/drama.wav will actually emit sound. However, the powermac toonie isn't detected by s-c-soundcard (gives error that there are no soundcards detected). In fact, if anyone looks at the gnome volume control, another bug is just waiting to be opened for that too ;-)
It's probing just BUS_PCI... we should at least add BUS_MACIO if not BUS_UNSPEC
Fixed for 1.2.11-5
