Soundbar 5.1 installed driver only shows stereo

Hi, I have (really don´t remember exactly how it was installed) the high fidelity playback (A2DP Sink, codec SBC) driver, and the SBC-XQ too

it’s supposed I have surround/5.1 but I only got stereo, both drivers

I must connect via bluetooh because the (only) HDMI port I use to connect the TV to my notebook: Acer Aspire E15

I don´t find the way to configure
there is no download a driver for my JBL Bar 5.1

any advise is welcome
