[Libreelec 9.95.2 / Raspberry Pi 4 / Kodi 19 Matrix] HDMI and analog simultaneous sound?

  • Switched from Libreelec / Kodi 18.9 Leia to the current setup.

    First problem was that I had no option for sound on the analog 3,5mm jack. Solved by adding "dtparam=audio=on" to config.txt. After that, in "Audio output device", beside the four ALSA vc4-hdmi devices I found also ALSA: bcm2835 Headphones. Which works. Sound comes either on the TV trough HDMI, or on the attached audio amplifier trough the analog output (yes, I know, poor man's setup).

    Now the question where I need help: how can I set up sound to come on both analog and HDMI simultaneous? Leia had this option and worked just fine, and that's what would fit me.

    Thank you, and keep up the good work :)
