There is an small bug when using the HDMI-CEC option along with the volume control option on the remote control.
The problem happens when the Google TV Streamer reboots while the TV where it is connected remains OFF.
As soon as I turn ON the TV, there is no audio output when I attempt to raise or to lower the volume level of the TV which is controlled by the HDMI-CEC feature along with the Auto (CEC) option in the "Volume control" setting of the remote control and the reason is because the internal volume level of the device gets reduced completely to zero.
I noticed this because when I go to the remote control setting and switch from Auto (CEC) to the "Google TV Streamer" option, when I attempt to raise the volume I see that it goes up to 15 again which is the maximum level the device has.
I recorded the following video where you can see the problem in action:

The only way I've been able to fix the problem is when I turn ON my AV receiver where I am able to hear sounds on the TV after I turn OFF the receiver, rebooting the Streamer doesn't fix the issue.
I already reported the issue through the form but I wanted to have visibility of the issue in the community since other users may have the issue as well.
Thank you for your attention.
