Odd. i2sbus should pull in all other required modules, and should itself load automatically at boot due to having a modalias that matches the of:... modalias the mac-io bus device for the i2s stuff has. > snd-aoa-codec-tas: found keywest-i2c-bus, checking if tas chip is on it > snd-aoa-codec-tas: created and attached tas instance > snd-aoa-codec-tas: found keywest-i2c-bus, checking if tas chip is on it > snd-aoa-codec-tas: created and attached tas instance Uh. That one I need to check, there is no tas codec on your machine. > snd: Unknown layout ID 0x44 That looks like you have snd-powermac loaded too. Or not? I don't think I have anything that prints "snd:" as the prefix but I might be wrong. > snd-aoa-fabric-layout: found bus with layout 68 (using) > snd-aoa: fabric didn't like codec tas > snd-aoa: fabric didn't like codec tas > snd-aoa-codec-onyx: found pcm3052 > snd-aoa-fabric-layout: platform-onyx-codec-ref doesn't match! > snd-aoa: fabric didn't like codec onyx > snd-aoa-codec-onyx: created and attached onyx instance > snd-aoa-codec-onyx: found pcm3052 > snd-aoa-fabric-layout: can use this codec > snd-aoa-codec-onyx: attached to onyx codec via i2c > snd-aoa-codec-onyx: created and attached onyx instance Most of this is due to that device-tree bug on those machines. > For the record, there are two "layout-id" properties in my device tree, > as discussed in this patch: > http://patchwork.ozlabs.org/linuxppc/patch?id=4867 Note that the patch is mine :) But also note that this isn't the reason that there are two layout-id properties, there really *are* two sound nodes with layout-id property because there are two i2s busses for the two codecs. > Ultimately, snd_aoa_codec_onyx seems to be the happy module.

Should it? Yes, it should. I think the bug is that the tas module thinks it can attach a codec here. Can you try *not* loading that module and see if it works better then? I'll try to see if I can make the tas module not attach on those machines, but as long as you don't load it manually all should be fine. > Also, it would be helpful if the git tree were better publicized > somewhere (e.g. http://johannes.sipsolutions.net/). I had to dig through a LOT of mails to find the source. Sorry. I linked it up on http://johannes.sipsolutions.net/Projects/ and will add a few more details later. johannes
