wrong or no album cover in soundbar

[dpaessler]

Expected behavior

Seeing the actual small album cover preview near play buttons not only in album mode

Actual behavior

If in album mode, it changes to the correct new one when selecting a song from another album with a different cover.
However, in all other modes selected at the left (artists, genres etc.) the cover doesn't show up at all or stays the last one when played in album mode before and doesn' change.
So it could happen that the wrong cover is shown when playing first in album mode, then switching to artist mode.

Steps to reproduce the behavior

1. start playing in album mode, small cover preview is visible and changes correctly when new song starts
2. switch to another mode and select another song from another album, the previous (and now wrong) album cover is still visible and doesn't change anymore
3. start playing directly from another mode, no album cover at all is visible near the play buttons

Possible solution (optional)

best solution would be displaying the correct cover preview no matter what mode is active
