Update! It appears that there just needed to be new modules written for alsa for the new hardware. over at http://ubuntuforums.org/showpost.php...7&postcount=42
the solution has been posted. It works for the new 13" and 15" macbook pro's. I would guess it works for the 17", but I haven't heard of anyone doing it.
To summarize, you need to download ftp://ftp.kernel.org/pub/linux/kerne...napshot.tar.gz
, extract the file, then change to its directory.
$ ./configure --enable-dynamic-minors --without-oss --with-cards="hda-intel"
$ su -c "make install"
After that, restart, and unmute the volume however you like. I went to the advanced volume control under system>preferences (because I know little about Pulse) and unmuted the "front speaker."
I found no need to delete the old alsa modules as the linked guide says.
The only hitch is that the internal speakers don't mute when headphones are connected.
I have one of the newest 15" MacBook Pro's, and I can't get sound to work. The speakers and the headphone jack make no noise. After installing pavucontrol, I was able to get noise in pidgin and mplayer through bluetooth, though not flash in firefox.
Lspci shows my sound card as: Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1).
I've tried adding "options snd_hda_intel model=mbp3" and "model=3stack" to a sound.conf file in /etc/modprobe.d
edit: apparently its a problem with other new MacBook Pro's. Watching this thread: http://ubuntuforums.org/showthread.php?t=1188849
