Bluetooth output sound doesnt work into MTO2 when GTV-BT1 sound control set on sound system

Im using a Formuler Z10 Pro Max with a GTV-BT1 remote.

into the Formuler Remote APP, GTV-BT1, Setup Volume Control is set to my sound system.

That is working well.

Here my problem... at evening, I ask often to my kids to used bluetooth headphone.

So, Ive successfully connected our bluetooth headphone to the Formuler.

When I move into Main menu, I ear the clicking... so Its working!

The problem come from MTO2. I cannot ear sound for Live TV, Movies or Series. Because sound is SET to my Sound System, volume plus or minus doesnt do anything to the bluetooth sound volume

My enhancement request ...As soon as there is a Bluetooth sound device connected, remote must control BLUETOOTH volume and nothing else

is it possible?

My work around... remove, from Formuler Remote APP, sound system control everytime Im using bluetooth headphone. Annoying!

Thnank guys!

Actually... the behavior is the same on all APP.

As long as my remote control my sound from my external system sound, it doesnt control Formuler hardware sound anymore.

is that answering your question?

I realized that there was 2 problems in my problem:

1- Cannot control Bluetooth volume with remote because remote is set to control Sound System. However, just you ask, I can control volume from my bluetooth headphone (tested!). Its doesnt control the Formuler Hardware, but Headphone hardware. Its a acceptable by pass.

My opinion: put an option like: "Priority Bluetooth Sound Control" toggle ON/OFF

2- Cannot ear sound from passtrought sound (Digitial Dolby, DTS, etc.) in my bluetooth headphone. However, Youtube seem work. (stereo sound maybe). Its there any possility to toggle on/off Passthrough sound? That option was there on Formuler Z8 Pro and isnt there on the Z10 Pro Max
