Delay playing track with upnp

Issue description:

I’m experiencing a delay of several seconds starting each track when casting to upnp. Things work fine when using Chromecast. I’ve uploaded a debug log file created when then issue occurs.
Can you suggest anything to improve this please. I’m casting to Argon Forte A5 WiFi speakers. I experience no delay when using the playfi app casting from Amazon Music.

In the logs you are playing offline cached media.

From the next button to the play command accepted by the renderer there’s 180 ms.

The renderer starts reading from Symfonium webserver 300 ms later.

I have no control over the second 300 ms delay, and no control about the time it decide to play media after that either.

Try to play directly from the server to see if it’s wifi speed problem on the phone.
