No the thing is i'm using the ac'97, another poster used a creative card and
still i've seen other complaints with X-Fi and many other cards, (a microsoft
phone rep confirmed this with me and told me to post it as a suggestion here)
this is not card-specific...

Uhm yeah im not sure how to actively suggest something to the error-fixing
people of Microsoft but I have a bug of sorts to report -

When using 5.1 speaker configuration the option under audio configuration
of
full-range satellites does not appear to work for rear satellites whether
enabled or not.
The result is drastically limited range on rear satellites whether you
like
it or not.

I have confirmed this with a number of other forums such as winamp and
hydrogenaudio etc with numerous sound cards and speaker sets.

I'm sure its not such a big probelm to fix with Windows KB.

PS. related to many other forum members I have helped out in this regard
please do something in the next release to make "speaker fill" set to
default
"on".
