Public bug reported: I don't have any audio output through the laptop's internal speakers but I get audio fine if I plug in external speakers.
I can get audio working briefly by running sudo hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0 as suggested at http://lkml.iu.edu/hypermail/linux/kernel/1301.1/02917.html but it doesn't last very long before the audio turns off again.
