media_player does not play a playlist

[donburch888]

The problem

Using the built-in HA media_player, selecting a MP3 file from the Media sidebar – it plays on my RasPi satellite as intended. Selecting a .M3U playlist from the same folder nothing plays.

Same behaviour using Developer Tools. and I hear the music play :-)

However when selecting a .M3U playlist file in the same folder, despite the green tick, no music plays.

I have not found any error at the time this occurs in any of the HA Logs.

I have placed files in the local HAOS /media/ folder, and checked that the playlist file contains correct filenames in the same folder.

#EXTM3U
#EXTINF:261,Il Volo - Il Mondo
01-Il Mondo.mp3
#EXTINF:220,Il Volo - 'O Sole Mio
02-'O Sole Mio.mp3
#EXTINF:243,Il Volo - Surrender (Torna A Surriento)
03-Surrender (Torna A Surriento).mp3
#EXTINF:292,Il Volo - Smile
04-Smile.mp3

Additional information

I have uninstalled Music Assistant to check that wasn't the cause.

I have tried with MPD and with squeezelite on my RasPi client, with same result, so I assume problem is not at the client end.

Is this because the entries in the playlist are simple local filenames (on the HA server) - but on the client they each need to be translated to URLs ?

Same behaviour with MPD or squeezelite on the RasPi satellite.
