Re: [gentoo-user] sound on intel imac [solved]
Hello Daid, Thanks for your reply. daid kahl daid...@gmail.com writes: # emerge alsa-util alsa oss ...and alsa-utils I should go to sleep... After my post I knuckled down and worked systematically through the model= options for ALC883/888 and ALC882/885, having gleaned from the internet that these are most similar to the 889A. The possible choices are listed in /usr/src/linux/Documentation/alsa/HD-Audio-Models.txt. Several choices produced sound, but only this (for ALC882/885): options snd-hda-intel model=mbp3 in /etc/modprobe.d/alsa.conf, followed by running update-modules, produces sound and turns off the speakers when the headphones are plugged in. This was one of the options I tried before posting, having found it using google, but it did not work. I _think_ I made the mistake of rerunning alsaconf after editing /etc/modprobe.d/alsa.conf, which of course erased my edit! Dumb. Best wishes, Roger

After my post I knuckled down and worked systematically through the model= options for ALC883/888 and ALC882/885, having gleaned from the internet that these are most similar to the 889A. The possible choices are listed in /usr/src/linux/Documentation/alsa/HD-Audio-Models.txt. Several choices produced sound, but only this (for ALC882/885): I had some trouble getting everything working on a newer kernel. I'll post the solved results of that on this list presently. If I didn't suggest it, pommed is a nice little daemon for using the Mac hotkeys. It was doing silly things today, but once I rebuilt and had the correct kernel settings, all was good. My sound was going to 0 at around 30% today, which was some interference between an older kernel and a newer kernel settings. Startup gave me funny messages about the sound card whenever I'd boot directly from one kernel into another, and I decided once everything else was working, if I just switched to the older kernel and back to the newer one, it could properly initalize itself. It worked! Who knows with these things.. Let me know if you need any other hardware working, since I've got it all I think. (Never tested bluetooth, but it shows up, and I deleted my old IR setup since I switched away from KDE, but it worked.) Regards, daid
Re: [gentoo-user] sound on intel imac
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 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 also use a Mac (though a different model). My suggestions might be naive, but did you be sure to do all the following? # emerge alsa-util alsa oss # alsaconf # /etc/init.d/alsasound start # rc-update add alsasound default If you don't run alsaconf, it won't work...I had that problem for a few days in 2007. Regards, daid

[gentoo-user] sound on intel imac
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
