DOS 2.11.3 is released

You enter Optical Direct Mode by rapidly pressing the Power Button 5 times. To exit Optical Direct Mode, hold it for 7-10 seconds.

I tried this on my two Silvers and it appears to work.
The side effect is the web page on the speakers stopped working and they also disappeared from the IOS app.
So I'm effectively blind.

Also this does not work for my Reactor 900.
Think the Reactors are not supported.
