I did run make install and have just done so again to make sure but it's 
not in /usr/local/share/aclocal either. I will copy it over and try 
recording again (see below).

Also I get this for snd-usb-midi
----

I just tried recording using the new code and completely hung the 
computer where only alt+sysreq+b worked. That was during recording.

The other person who is debugging with me has experienced simlilar as a 
kernel oops. He is currently using the patch to cvs but he will update 
soon I think.

This is what he said:

2) Kernel Oops:
The compilation of the source was rather a nice thing. I build some RPMs 
from
yesterdays snapshot to be able to clean up things after I installed them.
After installing, configuring modules.conf and removing my old 
asound.conf the
module probed finely.
I attached a copy of the aoutput of "arecord -l"

Recording was a bit messy, due to killing the arecord process freezes my 
box.
Deterministically: whenever the process is interuppted (Ctrl-C) or killed
(sig 9).
I attached a copy of the kernel-oops.
