Today I used for the very first time the headphone jack on my BV10 (2012 model, without the "external" camera connection panel).
After finding the right spot (let's say the connections panel of the BV10 could have been more user-friendly...) I plugged in my new Beoplay H7.
With the cable connection, the behaviour is as per the user manual, i.e. muting mutes the speakers and following volume adjustments are directed to the headphones only. Unmuting enables the speakers again. All fine here.
Then I connected a bluetooth transmitter (an apt-x model from a company called Aukey) and paired the headphones. Sound is clear, no delay. But there is a but.
When the BT transmitter is connected and I mute the TV with the Beo4, the TV does not mute only the speakers, but the headphones as well. How can this be possible? From the TV point of view, the bluetooth transmitter is a dummy/passive receiver exactly like a pair of headphones.
This means that the only way to use the headphones is to lower the volume to 01 (volume in the headphones stays constant somehow.. is this normal?).
I'm not terribly bothered because I can raise the volume from the H7, but I wonder why the TV behaves differently between the two modes.
FYI Beocare answered. I was obviously wrong in my assumption that the TV is not able to differentiate between a pair of headphones and a transmitter.
Anyway the Aukey transmitter I'm using is crap because when a movie is near silent the transmitter completely silences the connection and takes a good fraction of second to restart transmitting when it detects dialogue. I should receive a new transmitter today from a Norwegian company called Telme2. Hopefully it does not suffer from the same shortcomings.

"Your BeoVision 10 has a sensor in its jack-connection that tracks the impedance from the connected source.When you connect the headphones via cable, it can tell that a pair of headphones is connected and will then let you mute the TV, without muting the headphones.Once you connect the Bluetooth transmitter, it is able to tell that headphones are no longer connected, and therefore it will mute both the TV and the signal to the Bluetooth transmitter.Unfortunately I do not have a solution to this, but rather a work-around.This work-around was mentioned by yourself and that is to lower the volume to 01 on the TV and have the headphone volume stay at a normal level."
