Hi Stefan Many thanks for this patch. It fixed sound on my iBook that had previously used snd-powermac. Do you think you could send it to the linuxppc-dev list like this person did for a different version of the Powerbook 6,5 https://www.mail-archive.com/linuxppc-dev%40lists.ozlabs.org/msg66841.html ? That way it could get included in the kernel. I made a slight modification to your patch: + { .device_id = 38, + .codecs[0] = { + .name = "tas", + .connections = tas_connections_noline, since my machine has no external line-in/outs For some reason though, I still get a line-in showing in the sound mixers. It's not a big thing as I just need to select Microphone to record something. Also, in pulseaudio the output port is always shown as headphones. This is not really an issue since using snd-powermac it always shows "speakers" even when the headphones are connected! Like you, I also needed to add snd-aoa-i2sbus to /etc/modules. If certain machines are migrating to snd-aoa then the debian installer will need to be changed as discover-mac-io blacklists the snd-aoa modules. Has anybody got any ideas how this can be done?
