I managed to pair SWYH with Sonos Connect too. Works well both with mp3 and pcm streaming.
The only problem is the quality of the sound. When I stream tracks through SWYH to Sonos, the sound totally lacks bass and low-mid frequencies. It looks like SWYH cuts frequencies during the encoding process.
When I play the same tracks directly through Sonos player, they sound perfectly and no issues with bass frequencies.
Has anybody noticed that?
