Hmm... I haven't changed sbxfi code since yesterday.
The last change was:
   commit 941ec54e47f635f63621d3852253d9ef9b11132f
   Author: Takashi Iwai <tiwai at suse.de>
   Date:   Tue Oct 28 08:00:24 2008 +0100

      sbxfi - Use 48kHz as default

Though, I'm glad to hear that it's working, of course :)

Or, did you apply my last patch I posted?

The flash with PA can work with libflashsupport.
It'd be better to use it with flash-10, though.
