Added 'options snd-hda-intel model="olpc-xo-1_5"' to /etc/modprobe.d/alsa-base.conf in order to fix the speaker/headphone issue; both work properly after adding: internal speakers turn off when headphones plugged in, and turn back on when headphones are unplugged. However, now the internal mic no longer works (external mic plugged in does work).
