1. What happened

MOAS (Mute Other Audio Sources) does not mute Spotify app OR mute both Unity app and Spotify app on certain Android devices

Actual Behaviour:

• Both Spotify and in-app audio are playing. (2023.2.0+, Samsung SM-T575, as reported by the client)
• Both Spotify and in-app audio are muted. (2022.3.11+, Google Pixel 4a, tested locally. However it seems to be working correctly in 2023.2.0+)

Expected behaviour: In-app audio is playing while Spotify is muted

2. How can we reproduce it using the example you attached

• Build and open the app.
• While in, open the notification bar and resume Spotify music.
• Witness that upon closing the notification bar, both Spotify and in-app audio are playing OR both Spotify and in-app audio are muted

A similar fix was previously implemented https://issuetracker.unity3d.com/issues/android-muteotheraudiosources-not-muting-background-music-when-starting-the-player but it probably didn't cover this case?

Note: Issue was not reproducible by CQA
