Openhab-addons: [sonos, echo] Notification with say-command not always played!

[JueBag]

Playing a TTS notification sound isn't working under some cirumstances, probably cause by a changed behaviour on how the echo device selects and sends the URI to the SONOS devices.

For german public radio stations ("öffentlich-rechtliche") Amazon is using now the "ARD Audio Mediathek" instead of TuneIn, When asking for such a station the Echo device installs the respective skill to use this source automatically. IMHO this change is causing the bug.

I did some tests and logged the corresponding current Track URI and current AV Transport URI:
Running openHAB 2.5
No change on "other" radio stations:
TuneIn Radiostation [(Absolute relax (Easy listening)]
Started via Sonos App:

AV Transport URI:
x-sonosapi-stream:s158432?sid=254&flags=8224&sn=0

Say Command working!

Started via Echo:

German Radio Station
Radiostation NDR2

Started via Sonos App using TuneIn

AV Transport URI:
x-sonosapi-stream:s56851?sid=254&flags=8224&sn=0

Track URI:
x-rincon-mp3radio://http://ndr-edge-2040.fra-lg.cdn.addradio.net/ndr/ndr2/niedersachsen/mp3/128/stream.mp3?ar-distributor=f0a1
Say Command working!

Started via Sonos App using a link provided by radiostation, although SonosApp still states TuneIn Radio!

AV Transport URI:
x-rincon-mp3radio://http://www.ndr.de/resources/metadaten/audio/m3u/ndr2.m3u

Track URI:

x-rincon-mp3radio://http://ndr-edge-2065.fra-lg.cdn.addradio.net/ndr/ndr2/niedersachsen/mp3/128/stream.mp3
Say Command NOT working! This is more a "secondary" problem!

Started via Echo: (Echo states its from the „ARD Audio Mediathek“, Sonos shows ARD instead of TuneIn)

AV Transport URI:
x-rincon-mp3radio://https://ndr-ndr2-hamburg.sslcast.addradio.de/ndr/ndr2/hamburg/mp3/128/stream.mp3?ar-distributor=f0e2

Track URI:
x-rincon-mp3radio://https://ndr-edge-10b2-fra-dtag-cdn.cast.addradio.de/ndr/ndr2/hamburg/mp3/128/stream.mp3?ar-distributor=f0e2
Say Command NOT working!

Ok I see in the code why notification is not working in this case. Only
x-rincon-mp3radio with particular URL (tunein I guess) is supported.
I will try to fix that.

Thanks, but don't hurry!
