I recently setup my new Sony Bravia and the Playbase worked great. I could control the volume of a cable box, Netflix, Prime, etc, with the Sony system volume.
I then fired up Youtube and the remote wouldn’t change the volume. I used the playbase hardware buttons to lower the volume, and subsequently the remote won’t change the volume of anything when controlling the Playbase (it of course works when I switch it to TV speakers).
I’ve tried to unplug and plug in the Playbase and factory reset the TV to no avail.
Any ideas?
