Play a playlist of local music (NAS)

Hello guys,
I try to play a playlist from my NAS at my devices controlled by HA. (mounted to /home/pi/.homeassistant/media/music or access by http)

To play just a MP3 is possible by http… but if I select a playlist, no sound :frowning:

Device: Onkyo receiver, Yamaha MusicCas or Apple TV3

works
entity_id: media_player.onkyo_receiver
media_content_type: music
media_content_id: http://storage/aabbccddeeffgghh.mp3

works not
entity_id: media_player.onkyo_receiver
media_content_type: playlist
media_content_id: http://storage/aabbccddeeffgghh.m3u

As well I tried to use “DLNA”

How do you play your local music? Could “emby” a solution?

Can you play the playlist without HA ? ie from the amp?

File Explorer and IE Tab works. Now, I can play via Apple TV. But e.g. stop and next track is not working. As well via Onkyo receiver, Yamaha MusicCas is not working.
