[arch-general] Got Dummy Output after recovered from Suspension

[Robert Wong]

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:

Have no idea what is going on. Any help would be appreciated. Thanks.
