The model is Dell Inspiron 7560. The system got no sound after
recovered from a suspension. After reboot, got Dummy Output. Have
rebooted for several times, but useless.
Re-enabled sound controller in firmware, not work.
Reinstalled latest linux kernel as well as pulseaudio, not work.
Ran the following commands listed below, got the following outputs:
