Strange Audio "pause behavior" when pause a movie

[iz8mbw]

Bug report

Kodi goes to "pause" audio stream when we put in pause a movie and this causes some audio lost after resume playback.

Describe the bug

As already discuessed here #15601 (comment) when we go to put in pause a movie (a content) Kodi will go to "Pause" the audio stream and later will go to "resume" it again.
On the AVR I see the codec disappear and after about 500ms appear again, and this happens when the movie is still in pause!
When I play again the paused movie (resume playback) on the AVR I see the codec disappear again and after about 500ms appear again (so video starts before the audio) and so we will lost some audio moments because video starts a little bit before caused by this "strange pause audio behavior"....
This happens when "Keep audio device alive" is enabled (since "Keep audio device alive" is enabled I expect that Kodi will NOT to go to do nothing).

Instead if we go to disable "Keep audio device alive" it's worse because the behavior is the same but it's more "slow" because when Kodi will go to "pause" the audio stream, the codec on my AVR will change from the movies' codec (example Dolby Digital) to PCM and when I resume playback changes again from PCM to the movies' codec (example Dolby Digital). Also in this case we will lost some audio moments because video starts a little bit before.

Expected Behavior

What I expect is: if I put in pause a movie then NO new "audio stream pause/interruption/signal" should be sent.

Actual Behavior

Described in the "Describe the bug" section

To Reproduce

Steps to reproduce the behavior:

1. Put in play (in audio passthrough) a movie
2. Put in pause
3. Resume playback
