HTPC GPU Upgrade / No more DTS-HD and buggy audio :(

Hello Kodi people Wink

I upgraded my HTPC with a new GPU (AMD RX460), install the driver (AMDGPU-PRO v16.50) and now I have 2 issues in Kodi 16.

my custom HTPC is link via HDMI to an AV receiver Onkyo TX-SR333, my tv is a Panasonic TX-55CX700.

Problem #1 No sound at all when playing DTS-HD files (passthrough isn’t working anymore 🙁 )
The intel HD graphics and the integrated HDMI in the motherboard used to work perfectly in my setup, I can’t manage to make it work againSad

Problem #2 The sound is buggy and laggy when playing dts or dolby digital video files…

my etc/asound.conf:

Code:
cat /etc/asound.conf
defaults.pcm.card 1
defaults.pcm.device 3
defaults.ctl.card 1

aplay -l

Code:

I use this script to start kodi to disable pulseaudio:

Code:
#!/bin/bash
# Kill PulseAudio so XBMC will use ALSA for proper passthrough support
echo autospawn = no > ~/.config/pulse/client.conf
killall pulseaudio
# Start XBMC
kodi-standalone
# Restore Pulse Audio
rm ~/.config/pulse/client.conf
pulseaudio --start
