Over the past couple months I have got Gentoo working extremely well in most ways on my macbook. Unfortunately, I still have no sound, and I haven't yet found a working solution that someone else posted. So here is where I am now:

Also here is my kernel (2.6.34-gentoo-r1) configuration regarding sound:

As an example, if I open VLC and try to play an mp3, I get this message in the console:
| Code: | [0x758ca8] main demux error: no meta reader module matched "any"
QPainter::begin: Paint device returned engine == 0, type: 1 |
and then it looks as though it is happily playing the file, except that no sound comes out of the speakers or headphones. The same happens for other audio types, or avi videos with sound (the video plays fine as well -- just no sound).
Messing with alsamixer does not seem to have any effect, even with every bar unmuted and turned all the way up.
Any ideas? Much appreciated!
Matt

| I believe oss is conflicting with alsa. Either unload your oss modules or remove oss from your kernel. oss is deprecated. |

| Well, as shown I have the alsa oss (e.g. CONFIG_SND_MIXER_OSS and CONFIG_SND_SEQUENCER_OSS) stuff turned on, but CONFIG_SOUND_PRIME is definitely off. I'm assuming you're talking about that, not the alsa stuff? I'll try turning off the alsa oss stuff to see if that makes a difference though. |

Okay, I have some time again, so it's time to try and get the sound going again!
I upgraded to the newest kernel (2.6.36-gentoo-r5), and here's what I've got for sound:

[ ] Verbose procfs contents
[ ] Verbose printk
[ ] Debug

...

If I run alsaconf, I get the following message:
| Code: | | No supported PnP or PCI card found. |
Lastly, if I run VLC, it starts up with this error:
| Quote: | Potential ALSA version problem:
VLC failed to initialize your sound output device (if any).
Please update alsa-lib to version 1.0.23-2-g8d80d5f or higher to try to fix this issue. |
Naturally:
| Code: | # emerge --info alsa-lib
media-libs/alsa-lib-1.0.23 was built with the following:
USE="(multilib) python -alisp -debug -doc" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" |
Any ideas? Much appreciated.

Check alsa-info, but as far as I googled, you may have luck with 'model=mbp5'.
Also, 'Verbose procfs contents' and 'Use HR-timer as default sequencer timer' shouldn't hurt. |

I ran alsa-info, and I'm not sure what to do with its output. Although, embarrassingly, I did find that I have a 5,1 macbook, rather than 5,5. I'm not sure how I could have gotten that wrong. If it means anything, alsa-info does say this much:
| Code: | !!PCI Soundcards installed in the system
!!--------------------------------------
00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1)
!!Advanced information - PCI Vendor/Device/Subsystem ID's
!!--------------------------------------------------------
00:08.0 0403: 10de:0ac0 (rev b1)
Subsystem: 10de:cb79 |
So alsa-info finds the PCI card, while alsaconf does not. Why would that happen? |

I had the very same problem and symptomps. All I needed to do was enable "Build Realtek HD-audio codec support"
CONFIG_SND_HDA_CODEC_REALTEK=y
EDIT: I have Asus PRO66I and my card is: | Code: | | PCI bridge: nVidia Corporation MCP79 PCI Express Bridge (rev b1) |
