webos: No sound when using Starfish passthrough

[timfehr]

Bug report

Describe the bug

When using the Starfish passthrough audio device I hear no sound when playing media files. My TV is a LG OLED C9 running webos version 05.30.40 with Kodi 21. The TV is connected via eARC to a Denon AVR. When using internal apps like Netflix the audio is passed to the AVR without problems.
But when using Kodi the AVR show that there is no audio signal coming from TV. If I switch the audio device in Kodi to ALSA default. I get sound, so it seems using Starfish passthrough is the problem.

Expected Behavior

From what I read in the wiki and the forum passthrough should work ob webos.

Actual Behavior

Starfish passthrough audio is not working with LG OLED C9 running webos 05.30.40 with Kodi 21
