Trying Sonos Roam with HA like this:
service: media_player.play_media
target:
entity_id: media_player.sonos_roam
data:
media_content_type: playlist
media_content_id: >-
http://as-hls-ww-live.akamaized.net/pool_904/live/ww/bbc_6music/bbc_6music.isml/bbc_6music-audio%3d48000.norewind.m3u8
that works.
But ‘http://live-radio01.mediahubaustralia.com/DJDW/aac/’ (or ‘…/mp3’) does not. The speaker does not barf but does not play either. What is broken here?
Played a bit with settings and TVH and talked to Sonos community. So, these 3 work fine with the Sonos app and TuneIn:

http://as-hls-ww-live.akamaized.net/pool_904/live/ww/bbc_6music/bbc_6music.isml/bbc_6music-audio%3D48000.norewind.m3u8
Tried like this (the same in webui):
hass-cli -s http://hass:8123 --token xxxx -x service call media_player.play_media --arguments entity_id=media_player.sonos_roam,media_content_type=music,media_content_id=http://as-hls-ww-live.akamaized.net/pool_904/live/ww/bbc_6music/bbc_6music.isml/bbc_6music-audio%3d48000.norewind.m3u8
I tried all sorts of media_content_type, but HA’s Sonos only plays “bbc_6music”. What is missing?
freaking weird 
This works:
hass-cli -s http://hass:8123 --token xxxxx -x service call media_player.play_media --arguments media_content_type=music,entity_id=media_player.sonos1,media_content_id="aac://http://tvh:9981/stream/channel/9ce444d48e0008460df9ae9bd27a4f03"
So it has to have aac://http:// , http:// is not enough.
