This "default" key needs a simple value instead of a node.  The
"igetenv" call in alsa.conf uses braces because the call to "refer"
needs a node.

(Function calls replace their entire node with the function's return
value.)

I have replaced "default { 2 }"  with "default 2"  and it has worked.

Which character is this?

[EMAIL PROTECTED]:~$
  wc -l .asoundrc
11 .asoundrc

This file have only 11 lines not 12.
