If I connect an analogue source to a Connect, and have that music streamed uncompressed to, for example, a Play 1, then I can see that the bit rate is something like 1.5 Mbits/s, which is touch higher than a WAV file but close enough and therefore as expected.
I play my music using a Playbar (nothing to do with a TV, I just happen to have a spare Playbar). If I connect a digital music source via Toslink to a Playbar, and have that music streamed to a Play 1 then I can see a much lower bit rate: something like 400kbits/s.
The only explanations I could think of are:
i) The Playbar is compressing, lossy, (using SBC?).
ii) The Playbar is compressing, lossless, (using FLAC?) (to make transmissions to other speakers more efficient?)
Could anyone shed any light on this please?

"….the PLAYBAR compresses the audio to SBC and its bitrate is dynamic based on the number of components as well as the quality of the connection between said components. This would be equivalent to the Line-In compressed function…….[of Connect]"
