Port bit perfect?

As the ZP90 is being bricked very soon, does anyone know if the Port is bit-perfect?

In Fixed Volume the Port fills the top 16 bits on the S/PDIF only. The remaining bits are 0. The 16 bits are what comes out of the decoder, so basically it’s transparent.

Note that Variable Volume at 100% is not the same.

Lol. That made my day, seeing this in the midst of the firestorm. At this time no one cares; but my guess is that it is no different from it's immediate predecessor, the Connect. And not the zp90, that one preceded Connect.

Actually, a little known fact is the Connect bug that caused the non-bit perfect thing was fixed a while ago. As expected, nobody noticed. :grin:

Yeah, good to see the usual suspects - concerns I mean, not people. Hi res is missing will hopefully surface soon, so we can think business as usual.

You are a goldmine of interesting information! If I didn’t know differently, I’d simply assume you have access to the Sonos codebase.

I captured the S/PDIF data and analysed it.

I care. That makes one of me.

And is it identical to what is going in? The original question was about whether the Port is bit perfect. The Connect had volume limiting and a one-bit offset.

Cheers, Peter.

Interesting. Where is this documented?

It’s not. A little bird told me. That’s all I can say.
