Does the Sonos Line-in adapter transform the analog signal to a digital signal before delivering the signal to the speaker? Thanks for your help. :)

Yes, it does, except it’s an ADC, then a DAC to change it back for playback.

So it makes no sense because you dont get the original signal into the speaker

Why would you care? The signal is converted to lossless, which means no information is lost when you convert it back to analog. For all audible content, there is literally no difference between the signal in and the signal out of an ADC-DAC process when lossless is used.
