Update to this post about installing Fedora 10 on a brand-new MacBook…

To make the sound work, at least from the headphone jack, I had to run this command, from a guide Naresh put up on his blog…

echo “options snd_hda_intel model=mbp3” >> /etc/modprobe.d/sound

This sets the soundcard model option for the sound server. I then followed this guide to get PulseAudio running by changing one line of the pulseaudio config file /etc/pulse/default.pa, adding tsched=0 to the end of the line load-module module-hal-detect. It also directed me to install a bunch of PulseAudio packages, some of which don’t exist and others I didn’t need. The command I ended up running is below. I’m not sure if all of these packages are necessary; most of them were already on my system. In any case, sound works now. Out of the headphone port.
