This is what I have running on mine by way of modules for sound. I also had to modify dmasound_core.c to take unsigned input. i2c-keywest 4864 0 (autoclean) i2c-dev 5120 0 (autoclean) i2c-core 14816 0 (autoclean) [i2c-keywest i2c-dev] tumbler 2144 0 (autoclean) (unused) dmasound_pmac 33792 0 (autoclean) dmasound_core 13200 0 (autoclean) [dmasound_pmac] soundcore 5008 3 (autoclean) [dmasound_core] Hope this helps a bit j
