44.1 16 bit files not showing as lossless to Sonos, just as High Quality?

[Shawn_Oliver]

The Sonos S2 can handle 44.1 16 bit files and so can Airplay 2, here I’m playing a 16bit 44.1 file and it doesn’t show as Lossless, why is that?

Thanks!

Nevermind, I readded the Sonos devices via Sonos Streaming and she’s workin’ as expected:

Airplay is always reported as high quality.

Playback of 44.1 kHz/16 bit material not bit-perfect over AirPlay?

It looks like we always consider AirPlay to be “High Quality” as opposed to “Lossless”. Thinking back, I remember why. There are two reasons for this: Many popular AirPlay devices perform internal format conversions that we know to be destructive (example: all AppleTV models convert 44.1k->48k). Since AirPlay streams are clocked at the source, they must either have fancy adjustable clock hardware that can conform to the stream coming from Roon, or they must perform DSP to resolve the clock di…

Thank you, I’m happy now that it’s running lossless up to the Sonos’s’s’ max bitrate and sample rate
