That the output will be exactly as the recording sample rates?

Yes, the STX is already bitperfect but you have to adjust the sample rate yourself.
These new drivers will adjust the sample rate for you if your playing a bunch of tracks of mixed smapling rates. As I said, some want them and other prefer and want the ability to resample.

have to revive this thread in case I missed something, but afaik those drivers with automatic sample rate changing are STILL not out, right?

Auto sample rate changing is actually out with the latest drivers (actually two revisions ago) but it only works under ASIO.

I personally use these however (they still have auto sample rate switching under ASIO) http://brainbit.wordpress.com/2010/07/19/asus-xonar-unified-drivers/

since I like to use wasapi I cannot use any of those drivers, because they all have problems with the sound making clicks and stuff when i.e. browsing through explorer.

therefore, I have to stick to the vista drivers 6.12.8.1756 from the installation CD (they work with win7 as well)

btw. you still have to change the bitdepth via asio tool manually, so it shoudlnt be entirely lossless if you switch from 16/44 to 24/96 without changing anything there, right? so whats the point then of having automatic sample rate, when bitdepth doesnt change automatically as well?

You should leave bit depth at the highest it support.  When you feed it a 16 bit source it'll output 24bits with 0's filled in for the other 8 bits.  Ie. it will not hurt the decoding so should be left on 24bit

ok thanks.

hows the bitdepth thing handled with wasapi? there dont seems to be any settings for it.

and afaik with the asus drivers, automatic sample rate change is still not supported via wasapi. thats at least what some guy at the jriver forum found out :(

Well yeah if you're gonna use WASAPI (as I do) then you don't get auto sample rate switching. To be perfectly honest, I left mine at 96khz.  It upsamples, but you know what, I either don't notice a difference or like the oversampled sound.  Either way, I'm happy.  Plus ASIO's gain is ridiculously high.
