TrueHD and DTS-HD MA passthrough under Linux - muncrief - 2018-02-16
This is just a quick note for those running Kodi on Linux who need full audio passthrough functionality via HDMI. Kodi 17.6 passthrough works beautifully on Linux, you simply have to launch it with a script that disables PulseAudio on entry and reenables it on exit. I run Manjaro (a bit easier to use derivative of Arch), and used to run Ubuntu, so here are the scripts I use for launching Kodi with full passthrough capability. There are three scripts - pulseaudio_start, pulseaudio_stop, and kodi_launch. The start and stop scripts are different depending upon the Linux distro you're using, while the kodi_launch script is the same for all. Simply create the appropriate scripts and place them in /usr/local/bin, make them executable, and then change your Kodi launcher to execute "kodi_launch" instead of "kodi."

Arch/Manjaro

pulseaudio_stop
--------------------
#! /bin/bash
systemctl --user stop pulseaudio.socket
systemctl --user stop pulseaudio.service
pulseaudio_start
---------------------
#! /bin/bash
systemctl --user start pulseaudio.socket
systemctl --user start pulseaudio.service

Ubuntu

pulseaudio_stop
--------------------
#! /bin/bash
echo autospawn = no > $HOME/.config/pulse/client.conf
pulseaudio --kill > /dev/null 2>&1
pulseaudio_start
---------------------
#! /bin/bash
rm $HOME/.config/pulse/client.conf > /dev/null 2>&1
pulseaudio --start > /dev/null 2>&1

All Distributions

kodi_launch
---------------
#! /bin/bash
pulseaudio_stop
kodi
pulseaudio_start
I hope this helps some of those who love Linux but absolutely must have that passthrough (like me)!

What system are you running on?

I created an account on this forum just to leave this comment saying how helpful OP's scripts are - I moved my HTPC from Windows to Ubuntu for stability, was disappointed to find out about the DTS:HD/TrueHD issue. OP's solution is the cleanest I've found so far.

I know this is an older thread, but I've used OP's scripts on my (k)ubuntu 18.04 system for a while now. I agree with the other response that this is the cleanest method for this.
I recently upgraded to 20.04 and had to modify the scripts a bit since pulseaudio kept respawning after I upgraded.
I ended up with something similar to OP's Arch scripts. Just tought I'd share this to hopefully help anyone upgrading to 20.04.
pulseaudio_stop
--------------------
bash:#! /bin/bash
systemctl --user mask pulseaudio.socket
systemctl --user stop pulseaudio
pulseaudio_start
---------------------
bash:#! /bin/bash
systemctl --user unmask pulseaudio.socket
systemctl --user start pulseaudio
