[Wine] more than 16 bit audio

No problem. Jack provides the framework for performance that you
require, and using wineASIO provides the "low-latency, preformace,
etc" that ASIO would provide in a windows environment, but interfaces
with Jackd.(jack for audio, but ALSA for midi in Wine).

Not sure. What is your soundcard?  Can you record audio files with
Linux apps, with ALSA and/or Jack??? (this would indicate that indeed
your .asoundrc is working.  when using jack, do you have Qjackctl
installed, or maybe patchage? - these apps will provide a GUI for
jack, and maybe your inputs are available to send to Wine/Audition
3.0...?   are you using "full duplex" in both your Wine application
(preferences?) and also Jack?

Yes, I am using Jack/ALSA. I'll put something together, but email it
to you... I'm not gonna post it on Wine-list, as it strays from what
this particular list is all about.

I assume you know about Gentoo's Pro-audio Overlay???  ~  google it.
(because you are using gentoo right?).

anyway, give me a day or so and I will send a few links, and how i
personally go about things. I don't use Gentoo but have, and from
using BSD ~ i am fairly familiar with it. You will basically either
want to compile an RT-kernel, or a very recent Kernel (i currently am
running 2.6.37.3), combined with BFS scheduler ( which can work quite
well, for audio stuff ), and optimize a few other
things, as well.
