Hello, I have a 20 inch aluminum imac:
uname -a Linux pyrope 2.6.30-gentoo-r5 #9 SMP Sat Nov 14 14:04:55 NST 2009 x86_64 Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz GenuineIntel GNU/Linux The sound card is listed by lspci as: 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) cat /proc/asound/card0/codec#0 says Codec: Realtek ALC889A I'm using the in-kernel alsa drivers. I have tried compiling into the kernel and as modules. I cannot get any output from speakers or headphone. (Yes, I have run alsamixer and un-muted everything). I have looked around using google and problems with the ALC889A codec seem common. I tried some of the suggested fixes, like setting model=whatever to the kernel snd-intel-hda module. Nothing I have tried has worked. I know the sound system is functioning because it works in OSX. If anyone here has any suggestions or knows for sure that the sound system on these machines cannot be made to work in Gentoo it would be useful to find out before I waste more time on it. Thanks, Roger
