   I have cvsup'd and rebuilt world today (2000-08-23). No more
clicks now from my sb16: the sound is simply perfect, but
occasionally I get the following error message:

Aug 23 21:05:45 goku /kernel: pcm0: hwptr went backwards 4128 -> 4112
Aug 23 21:05:45 goku /kernel: pcm0: hwptr went backwards 4128 -> 4112
