FIOS one October 20 upgrade-no audio

After auto install APR 7.0 build 28.49 FIOS One mini did not pass thru surround, only Stereo, regardless of audio pass- thru setting.

My ONKYO receiver displayed “HDMI Passthrough” and would not stay on any surround sound setting, like Dolby.

On FIOS ONE DVR after auto upgrade, there was NO audio connected to receiver or tv via receiver pass thru.

Both problems solved by disconnecting and reconnecting power. 

note in both boxes the Audio passthru default setting was changed to disable from enable after the upgrade, so be sure to enable it if you are using a surround sound receiver or sound bar.
