@Gale: When I tried Leland's fix I lacked 2 WDMKS inputs and the remaining 2 inputs were incorrectly named - as were the WDMKS outputs. MME worked fine for me. I think it's very system/driver dependent.
Also I forgot the debug log file code - sorry if you wasted a lot of time there.

Btw I dusted off and booted my very stale OSX 10.5 Leopard partition on this machine (yes it's a macbook, and I'm running WinXP on it!) to see if there would be any problems with audio drivers there for 2.0.4 - after all it's the same hardware. But it worked fine.
I also tried to compile Audacity from source, but got stuck in update-everything-you-have-before-you-can-do-anything-useful limbo. But this is not the thread for that.

OK I "assume" I patched it correctly using GNU patch - the SVN
diff then was the same as Lasse's diff.

But there is no debug log file, applying that patch on its own. Do
we want a log file like Leland's patches had? If so, did you want me
to apply Leland's patch, but using Lasse's pa_win_wdmks.c ?

I too think there are problems with Leland's patch, based on
the user comeback. In half the cases, MME is said to be missing
(at least on some launches), even though the hang was fixed.

I haven't seen any reported problems with missing inputs and
outputs after running Leland's patch, but WDM-KS is reported to
have that problem already on some machines in current HEAD.

Were you missing inputs and outputs under all hosts, Lasse, or
just WDM-KS?
