I tried 2.6.12-rc3-mm3 and seems snd-powermac loads (according to lsmod) but I get: [EMAIL PROTECTED]:/home/jas> alsamixer alsamixer: function snd_ctl_open failed for default: No such device and dmesg gives: ip_tables: (C) 2000-2002 Netfilter core team ip_conntrack version 2.1 (6144 buckets, 49152 max) - 248 bytes per conntrack device eth0 entered promiscuous mode ALSA sound/ppc/tumbler.c:1049: cannot find device audio-hw-reset ALSA sound/ppc/tumbler.c:1049: cannot find device amp-mute ALSA sound/ppc/tumbler.c:1049: cannot find device headphone-mute ALSA sound/ppc/tumbler.c:1049: cannot find device line-output-mute ALSA sound/ppc/tumbler.c:1049: cannot find device headphone-detect ALSA sound/ppc/tumbler.c:1049: cannot find device line-output-detect ALSA sound/ppc/tumbler.c:381: failed to set DRC ALSA sound/ppc/tumbler.c:244: failed to set volume ALSA sound/ppc/keywest.c:122: tumbler: -6 :cannot initialize the MCS ALSA sound/ppc/tumbler.c:1049: cannot find device audio-hw-reset ALSA sound/ppc/tumbler.c:1049: cannot find device amp-mute ALSA sound/ppc/tumbler.c:1049: cannot find device headphone-mute ALSA sound/ppc/tumbler.c:1049: cannot find device line-output-mute ALSA sound/ppc/tumbler.c:1049: cannot find device headphone-detect ALSA sound/ppc/tumbler.c:1049: cannot find device line-output-detect ALSA sound/ppc/keywest.c:122: tumbler: -6 :cannot initialize the MCS ALSA sound/ppc/tumbler.c:381: failed to set DRC Let me know what other info you perhaps need. > > > Also as a side note the readeonfb doesn't seem to work that good.
