AC3+ on GM Triplex

There´s no mechanism inside HDMU to change this file.
You have to put it in /boot:
Rename or save somewhere the existing audio.elf, and then copy the audio_dts.elf to /boot with named as audio.elf .
After reboot it will be loaded and works.

cool. and where can I get the audio_dts.elf?
