Can no longer hear music when playing to BM media_player on iPhone (app or browser)

[Mariusthvdb]

The problem

thought this to be an issue with Browser-mod at first, so filed this: thomasloven/hass-browser_mod#302

to cut it short: we can not play local files (from the /media share) to a mobile (iPhone) media_player anymore, even though some 6 days ago this was working perfectly: https://community.home-assistant.io/t/media-source-media-not-showing/229247/11 and https://community.home-assistant.io/t/migrating-media-files-from-config-local-to-media/395971

As I tested the files being playing from the www folder on the /config share once again (is what I did before the move to the /media share), and that works just fine, I must conclude this to be an issue introduced in the last couple of days in #beta 2022.3 and nightly dev builds.

more details:

Radio streams can be played to the mobile devices just fine, using a same script syntax and the same media_players. Also, TTS messages are played correctly.
