I have tried your suggestions (`aplay -l` and `alsamixer -c DEVICE_NUMBER`) and found the speakers muted, but unmuting did not change anything. Booting Ubuntu 16.04 shows the same issue of headphones working and speakers dead. I have the hunch that perhaps that a hardware defect tells the laptop that there is something plugged in although it isn't. And then there is probably nothing one can do with software.

Thank you for responding anyway, I have kept this response off the devel-list. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
