Where should i look since the kernel and modules are the same (are

By using the "stock" kernel, so you mean you compiled it from
vanilla,
or do you mean the standard kernel included with each distro.
If the latter, I assure you that the Mandrakelinux and Debian kernels
will be VERY different. We have a few hundred patches in our kernel.
If you're compiling from vanilla, there shouldn't be such a defference.
Maybe different alsa or glibc version?
Sorry for the imprecision, both system use
the vanilla kernel (preemption
disabled) from
kernel.org, both are compiled for an amd processor with the
same .config file.
The difference is such that on debian it's just impossible to use band in a
box with wine whereas it works great on mandrake!
Keep in mind that Mandrakelinux is i586
optimized, except glibc which is
i686 optimized. Debian is only i386 AFAIK.

Maybe this is the point but i don't know how to solve it.
I know that the glibc version differ between mandrake and debian i'll
investigate that.
I wonder if there is a place somwhere in mandrake's distro, where they tweaked
something to better the sound system ...(alsa option, IRQ fiddling, or
something...)
Since you already have debian sarge installed you might consider adding
packages from Demudi/Agnula:
At the very least you should be able to use their kernel .debs. I'm not
sure because I haven't used demudi yet myself, but it may be as simple
as adding a demudi line to your /etc/apt/sources.list and apt-get
install'ing the appropriate package(s).
For what it's worth, I do audio work on a debian sarge box. I'm using a
patched 2.6.x kernel. Others are having good success with low-latency
patched 2.4.x kernels on debian as well. I doubt differences in
processor optimizations between debian and mandrake are your problem.
Especially since you say you have the same kernel .config for both
installations.
