So, after this app debacle I’m on the hunt for technical solutions.
The one that I found is that I use Symfonium ( https://symfonium.app ) and oh great it supports UPnP ! I can play my files in the FLAC format (16bit/44.1 kHz) without problems !
But my music provider converts to OPUS 128kb/s for my smartphone because when I’m on the road… Roaming gets quickly expensive. I then get 48.0 kHz files that are then sent via UPnP to Sonos, just like FLAC.
According to https://docs.sonos.com/docs/supported-audio-formats, 48 kHz is supported for Opus. But it doesn’t work. Bummer.
But fear not I got one last card up my sleeve and it’s to transcode to MP3. So I’m trying MP3 320kb/s, in 44.1 kHz which again is supposed to work and… well, it doesn’t work.
I tried another UPnP device it was working flawlessly, and it even works over Chromecast… But we can all dream about Chromecast on Sonos when I see Apple and AirPlay working without problems it really sucks using Android with Sonos… :(
Any staff members or even devs to help me find why it is so stubborn even when everything is done by the books ?
