Have posted contents of asound in this thread bottom.
Seems ALL is OK. but aplay fails to open the /dev node

Well, shure it works but it is not a needed stuff.

About more than a decade without it and ALSA was PERFECT - really.
JACK+ALSA was a combination without much trouble.

If UDEV is causing this problem..... hmmmm I can not be shure so far.

The kernel driver seems to me the cause - WHY it can open the /dev node
in version 2.6x but **not** in version(s) 3.x ? 
It is the same device node, same perm, same MAJOR/MINOR... identical.

That is my/the problem... driving me nuts :)
The driver internals changed quite a bit.
