RPI4 with LE 10.0 dual audio mode

    Hello

    I have Raspberry Pi 4 with LibreElec 10.0 connected to my TV by HDMI cable.

    I would like to use Kodi in dual audio mode, because I would like to watch movies with my wife when children sleep;) so I need connect two Bluetooth headphones to RPI4

    I activated dtparam=audio=on in config.txt. so I can use analog

    Next i tried:

    PulseAudio - Official Kodi Wiki

    Step 1: Edit /etc/pulse/default.pa

    load-module module-combine-sink sink_name=combined

    Unfortunately I can't edit this file because of problem with permission. (warning no write permission)

    I can't find any way to edit this file.

    Can you help?

    I tried:

    mount -o remount,rw /

    don't help

    Maybe you have any other idea how to connect two Bluetooth headphones to raspberry pi 4 with LE?

    I will be grateful for any help

    Thank you so much Da Flex for your help.

    I create new file "custom.conf" in folder /storage/.config/pulse-daemon.conf.d.

    This file contain:

    "load-module module-combine-sink sink_name=combined"

    Unfortunately this is not change anything.

    There is no any new option in settings-audio.

    Should I do something more in this file to have option to connect 2 devices?
