Bug Description
Platform: digital audio G4 powermac
# modinfo snd_powermac
filename: /lib/modules/
license: GPL
description: PowerMac
srcversion: DC59E3D3DECC5C5
depends: snd-pcm,snd
vermagic: 2.6.31-14-powerpc mod_unload modversions
parm: index:Index value for PMac soundchip. (int)
parm: id:ID string for PMac soundchip. (charp)
parm: enable_beep:Enable beep using PCM. (bool)
I am assuming that snd_powermac did not load properly. An examination of 'lsmod | grep snd' shows the module is present but unused. In the past this problem has been caused by slot contention.
