[BUG] Playlist with mixed audio and video files is not correctly played

[Kasta-76]

Describe the bug

I use a mixed party playlist that contains audio files (Mp3) and videos (Mp4 or Url for Youtube plugin).
There are problems when an Mp3 song is followed by a video or vice versa during playback.

If a video follows an Mp3 the sound of the video only runs haltingly together with the audio visualization instead of the video. In some cases Kodi crashes with an exception instead.

If an mp3 follows a video, you will see the last image of the previous video instead of the audio visualization. The sound is OK.
Stopping and starting the respective file solves the problem but is very annoying.

How to reproduce

Steps to reproduce the behavior:

1. Create a mixed playist with an mp3 followed by a video (mp4 or link for youtubr plugin)
2. Play the first mp3
3. Wait until the song is played and the next (video) is started
4. Either kodi crashes with exception or you can hear the sound of the video together with the audio visualizaion
5. Stop and restart the video
6. Video is showing correctly
7. Wait until the video is played and the next (mp3) is started
8. The mp3 sound is played correctly but the last frame of the previous video is shown instead of the audio visualization
