Prado.
(or anyone else haveing probs. )
thanks for the pic showing the rme user control panel.
firstly you can upload pics fast to stashbox.org.
without even setting up an account.
after each pic upload a link will display.
just copy the link into the thread here.
as i said lets be constructive.
lets see pics of the following mate.
1. dpc pics for both the centrino and the xeon.
2. you showed the user control panel for the rme but not the echo.
(i'll get to the rme in a moment.)
3. pics showing settings in the daw software where asio works flawlessly
showing driver and sampling n bit rate settings.
4. pics showing your own biab preference settings for drivers/asio
etc etc.
5. and for the hey of it..cos it might be important...
a pic of win task manager showing all running tasks n processes.

this way a complete picture of both your xeon and centrino systems
can be obtained.
for anyone else haveing probs with a sound device ..
just post a thread in off topic with the above pics.
you could call it...the problem sound devices thread.
(many recording forums have a sticky thread relating to sound devices that work and dont work).
and i'll take a gander at the pics and comment appropriately ..fair ??
but i need those pics in order to help.

now back to your rme prado.
for you specifically.
(yes your link to the rme control panel is the sort of user control
panel i was talking about.
viz most sound devices , even junky on board pc sound has a user control panel.
and its sometimes settings in these user control panels that trip people up.
for example ive seen numerous threads on various forums with many different types of
daw software where people sometimes wrestle with various control panels like emu n delta etc etc.)

a couple of questions.
you obviously have a sophisticated set up with the rme.
1. are you useing external clocking devices with it. ??
2. in your other daw software where asio works fine..
what bit depth n sampling rate do you have set ??

do you now have rme and asio and biab working fine
includeing the x factor ?? whats your status ??

mebe it is an issue with biab implementation of asio..
but one can only state that categorically after
exhausting other diagnostic avenues which is why those pics are important.

as i said..for other folks ..post the above pics in a thread in
the off topic section. n i'll comment appropriately.
but i cant comment intelligently unless i have pics of peoples settings.
imho this is far more constructive than just ad hoc comments.
in fact i'll go now n start a thread in off topic called
"post your problem sound devices here".
so there is a central repository hopefully for folks .
fair ??
god bless mate.
