Hi Peter,

Thanks for the new version.
I have a question:

With the digital volume control what setting is bitperfect? 0db?

When I set it to 0db I have that sensation which I always have if a volume is changed in a digital domain.
So I suspect that with digital volume control is not bit perfect.

Yes, at -0dB the output is bit perfect. Also the "volume" is not in the way/path then. So the code for "no volume control" is dedicated to that.

So this is not consistent with reality then. no Or did you perhaps say something you did not want to say ? (because it looks a bit confusing to me).

Btw, only for 44.1/16 the code is unchanged. This means that the "DAC needs" buttons *must* remain unchecked.

I have a PCI audio card.

1. If I set its speakers interface as a default device in Vista Then I see XX engine 3 in the Vista Mixer, The Vista master volume affects the volume of the music.

2. If I use SPDIF interface a default device, then I don't see XX in the mixer, the vista volume control does not affect the music.

In both cases XX does not complain about exclusive mode. And in first case there is no sound level indicators activity in the Vista mixer while playing.

Is it bitperfect in the first case if I set the volume control at max?
How can record what is coming out to compare to the source?

Ok, so far I never saw (or heard of) the situation that loudspeakers connected to a soundcard could incur for "Exclusive Mode" (whatever that exactly is in this stage of "investigation").
Can you confirm dat this worked the same in 0.9t ?
Also, I assume you don't get any messages at the start of Playback ?

This is a quite undoable task, but which I solved for myself about a year ago by means of two Fireface devices. This is inherent to how Vista works and determines when to apply the proper Exclusive Mode. This is similar to connecting a DTS receiver and that just "proving" bit perfectness, which for Vista says NOTHING.
Currently I don't have the answer anymore, and it took me several days to set it up and prove it back then.

Lastly for now, do note that the situation exists that no volume amplitude information (the green bar) shows, BUT you can still switch off the volume with the bottom button (a red circle appears then). I never tested the true merits of that situation, but it sure is fishy. By me proven bit perfect situations can never switch off the volume.

Anyway if you can influence the volume with the master volume slider, I'll bet it's not bit perfect.

So far for now. Sorry ...
Peter

Yes it was the same with previous versions.

Have you seen XMplayer with WASAPI plugin. It locks my speakers interface as well as SPDIF for exclusive mode perfectly.
I don't think it beats SQ of XX but the exclusive mode it implements in a way differently.

Hahaha, yes, and with my Fireface and DAC behind it, it does exactly what you described before.
(And I found it sounding superbad, but that's another matter Happy)
