Force dts passthrough with setting?

[mafiosoking]

Hi guys
Is it possible to force 5.1 passthrough like on a rpi ? (see below)

# HDMI Force EDID Audio
# Pretends all audio formats are supported by display, allowing passthrough of
# DTS/AC3 even when not reported as supported.
hdmi_force_edid_audio=1

My LG tv supports passthrough, but doesn't work without the force stuff...
