I am using my Raspberry Pi 2 with an HDMI Monitor without Audio.
In LibreELEC, I need to enable the Audio Output on the 4-Pole (TRRS) Jack so that I can feed it to external amplified Speakers.
EDIT: I found the answer to this: It is in System/Settings/System/Audio Output and select HDMI and Analogue
(I still need to know how to edit the Config.txt file because the Pi 2 needs HDMI Boost set to 5)
Also, If I need to edit the Config.txt file, how do I open a Terminal session while running LibreELEC?
Any help would be much appreciated ...
