Got a slightly odd one here.
TL:DR - Volume changes only “TV” volume, not soundbar.
Have got two Bravia TVs integrated with the Sony Bravia integration, they are Android but I don’t use that integ, preferring the Bravia one. With those come the Media Players, which work great, including being able to adjust the TV volume. However, when volume is adjusted using this, it changes the “TV” volume (the OSD comes up and the number changes) but it does not change the volume level on the Soundbar (has it’s own display, and you can hear that there’s no volume change)
One TV is using Optical and the other HDMI ARC, so doesn’t seen to be related to that.
I’ve done tons of searching but can’t find any discussions on this topic. Anyone else seen the same, or has thoughts?
