I'm Here I'm here!!
I reported this bug regarding the issue:

https://bugzilla.gnome.org/show_bug.cgi?id=597001

And implemented this patch:

https://bugzilla.gnome.org/attachment.cgi?id=144504

I dobt the patch still merges cleanly but I can put this working again.
The problem is that with the corrent audio code (wich uses a systemcall
aproach to call gstreamer) it sounds a bit strange sometimes, with beeps
one over another. Maybe I'll try again wrting some gstreamer stuff and
see if it works... I recall problems with that on solaris and working
fine on Ubuntu... Is solaris still a priority? :)
