Ubuntu 64 quantal vs. Macbook audio
Posted November 27, 2012
No sound?
echo 'options snd-hda-indel model=mbp55' | sudo tee -a /etc/modprobe.d/alsa-base.conf
sudo killall -9 pulseaudio; sudo modprobe -r snd-hda-intel
Plugging in headphones mutes speakers but does not produce sound in headphones? Sound settings window reveals that the headphone sound begins if you select the "analog output" device, but pulseaudio automatically switches back to the "headphone output" output device when you plug in the headphones?
sudo cp -ip /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf{,.original}
sudo cp /usr/share/pulseaudio/alsa-mixer/paths/analog-output-{speaker,headphones}.conf
sudo perl -pi~ -e 's/(priority = )100/${1}90/; s/output-speaker/output-headphones\n\n[Jack InputDevice]\ncode = Headphone\n/' \
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf
reboot
