Alsa and HDMI audio output simultaneously.

  • I discovered to my great enjoyment that it's really easy to add spdif audio output to an old RPI 1-B (using LibreELEC (Leia) 9.0.0) with a simple usb sound-card. It was as simple as plugging it in and choosing the setting in the Kodi menu after a reboot. Nicely done!

    However, there is no setting to have the hdmi audio and alsa spdif output audio simultaneously as you can with the regular pi 3.5 mm analog output. Is there anything I can do to enable that?

    I've tried to google this of course but didn't find anything promising. I was hoping that some new possibilities were introduced with the latest Kodi and Libreelec. Any ideas?
