Volume not reset on device reboot if device is in sleep state when reboot occurs

[KathyReid]

Description of fault in object deviation format

If a Device is put to sleep with the sleep command - Hey Mycroft, go to sleep, then the Device is rebooted before the stand up command is given - Hey Mycroft, wake up, then the 'sleep' state is cleared by the reboot, but the volume level is not re-instated.

This was observed by Kathy when she had her Mark 1 asleep overnight, and the 18.2.6b release was pushed to the Device, and the Device rebooted. The Device's volume was entirely muted when the Device rebooted.

This results in the Device coming back up with the volume muted.

Workaround

The workaround is to:

• ssh into the Device
• run the command alsamixer
• use alsamixer to increase the volume

Expected behaviour

The expected behavior is that the Device's volume returns to that which it was set to before sleeping, if the sleep state is also cleared.

This Issue is being added to the Naptime Skill, because this Skill requests the muting
