Is ASIO is not bit perfect, or what to do with ASUS D2X

[HeadLover]

Hi
I have this card, and using FOOBAR2000 and ASIO (VISTA 64 bit BTW)
Any way
There is a control penal for the card, and u can set things like Dolby and so on
And they do change the sound!
How come?
And what can I do to make sure I get bit perfect from my card? what setting should be there? and what to do ?
Also there is a sampling rate in this control penal for the PCM, what should it be?
(can be form 44.1 to 192)

Thank you !

Oh my god, really? Wow! Well no ****!

Now that "Dolby" wouldn't be the "Dobly Virtual Speaker" would it? As in the software effect you're applying to the sound before output.

You're changing filters.

If you want bit-perfect, don't reclock, just set it to your content sample rate (44.1kHz for CD source) and obviously don't add any effects or filters.

I don't know about Vista doing bit-perfect output.

Just to make sure, you do know that "bit-perfect output" implies digital pass-through right?

amm I was thinking about analog to
And
How can I make sure my sound card setting are reset to ZERO DSP settings?
I can't see there any reset button (icon or what ever), and it will be nice rather than check all settings and not be sure about it
Also
there are things like "heapdhones" or "speakers"' that I can choose and many other settings
I want the most bit to bit I can get
How do I get it with this card and settings?
Thank you!

The 'Hi-Fi' mode button in the control panel removes all DSP settings, etc. Use that for unaltered audio.

As for bitperfect, I don't _think_ you can do that in Vista without using something such as ASIO or WASAPI, as supposedly Vista resamples all audio regardless of what you set it to (i.e. even if you set it to 16-bit/44100Hz, and play content with that same bitrate/sample rate, it will still resample it before output... hence you may aswell set a higher sampling rate). Having said that though Vista's resampling is vastly superior to XP's implementation, so I think you'd be pushed to hear any audible difference. Just my personal opinion.

I am using ASIO !!
So, I do want bit perfect
