I am using an Intel NUC linked to a Marantz audio-video-receiver via HDMI, which is then linked to my TV via HDMI also. I am running Kodi in order to use this setup as a media player.
On Ubuntu 16.04 and 18.04 I had Pulseaudio disabled in order enable audio passthough from the NUC to the AVR, so that the AVR would be aware that I was feeding it a certain kind of audio signal, DTS say.
I was using the setup described here https://kodi.wiki/view/PulseAudio/HOW-TO:_Disable_PulseAudio_and_use_ALSA_(without_removing_PulseAudio)_for_Ubuntu Short summary: I had /etc/pulse/client.conf adjusted in order to include
autospawn = no
After upgrading Ubuntu to 20.04 this option seems to no longer work, audio passthrough is disabled and the passthrough option is not available in Kodi's settings.
I also tried to run
KODI_AE_SINK=ALSA kodi
but this didn't work either. While the passthrough option re-appeared with this command line option, the feature still doesn't work and/or the video playback sound is just static or crackling (depending on the choice of settings).
So, my question is this: Is there any way to get Pulseaudio and ALSA to interplay as they did in the previous versions? I'm hoping to avoid having to downgrade to 18.04 in order to be able to use the audio passthrough feature again.
