Hi everyone. I recently installed Ubuntu 12.04 on an old MacBook. Everything seems fine except I can't get sound through my headphones. I can only hear audio through my built-in speakers. Whenever I plug in my headphones, there is no sound and there is a red light that glows from the jack.
I've searched for a solution online but so far nothing has worked. This link describes the exact problem but their solution for modifying the file /etc/modprobe.d/alsa-base.conf did not work for me: http://www.upubuntu.com/2012/04/headphones-not-working-no-sound-under.html. This other link also describes a solution by modifying the alsamixer. However, I do not see a headphone jack listed in the alsamixer. Does anyone have any suggestion(s) for me? Do you think that upgrading to a newer version of Ubuntu would fix the problem? _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
