The flags are 100% identical 
Can you try to cast from your local device via Symfonium a flac and not from subsonic?
It works with Symfonium when using local and not subsonic. Strange.
Well not that much in the end.
Do you have subsonic logs to see if thereās errors there ?
Iām not sure how to do that. I use Navidrome.
Iām running it inside of a docker container on my Synology NAS. Please give me a sec to get on PC and try the logging commands.
The one I marked in red is when I switch it to cast to my KEFās. The other two are when I still play locally (via built in phone speakers)
Ok so the KEF does try to read the media and itās an issue with navidrome webserver and itās headers.
Are you sure you were able to actually stream to those KEF from navidrome?
Navidrome is based on the subsonic api, I had it added in the Symfonium app as Subsonic Media Provider and I am able to stream it to my dadās speakers downstairs (Lumin). So yes streaming from Subsonic works just not on my KEFās.
Thatās not the question
The question is did you managed to stream to those KEF from navidrome from any other apps?
The issue does not sounds related to Symfonium but navidrome headers not love by the KEF.
I have not used any other apps other than Symfonium. I know that it works with DS Audio (by Synology) but that is not subsonic based as far as I know.
Actually, I used to use another app called subtracks but streaming to my KEFās did not work there either.
No itās not and the issue sounds specific to navidrome (or more your KEF) not subsonic in general.
Can you try to stream from Kodi or Jellyfin or other providers? Thereās not much possible things possible to workaround this issue.
Aww manā¦ Navidrome is this only one that offers a nicely looking Spotify lookalike web GUIā¦ the other ones all look so old school and ugly.
On my PC I use Navidrome in my web browser to play music, since thereās no Symfonium desktop app I looked for alternatives but theyāre all so ugly in my opinion.
Well you can try to contact KEF support and have them fix their firmware But good luck with that.
Other solution would require adding a reverse proxy and rewrite the headers from navidrome to something that the KEF likes but really advanced and out my support
Could you please add a toggle in the advanced settings that I can enable? Just warn the end user that it may consume lots of battery. I only really use these speakers at home with wireless chargers nearby so itās not a problem for me if thatās the case. Streaming with local provider instead of Subsonic worked for me so maybe the toggle could download the audio file from subsonic into my phone RAM temporarily and stream it locally from my phone to the speakers?
Itās probably tedious to do but Iād be very thankful.
(also I opened a KEF support ticket 3 days ago, nothing back from them yetā¦ But Iāll try 
)
Hey there,
Itās been a while and there have been quite a few updates to Symfonium. Iāve tried streaming to my KEF Speakers again and Symfonium actually wakes up my speakers and puts them in DLNA mode now, which it did not before. But the music doesnāt play and still gives an error. Aaarggghh! So close!
Iāve attached logs and hope it helps you out
