you know what, this is surprising for a few reasons:

1) two other users reported problems in playing 16-bit files or with
   mpg123;

> Lots of "WARNING: rdintr but read DMA inactive!" messages when cat'ing .au
> files to /dev/audio.

2) the above message should never come out with the SB16X: in fact
   there is

#define PLAIN_SB16(x) ( ( (x) & (BD_F_SB16|BD_F_SB16X) ) == BD_F_SB16)

        ...
	if (PLAIN_SB16(d->bd_flags))
	   printf("WARNING: rdintr but read DMA inactive!\n");

and PLAIN_SB16 should be false with a Vibra16X !
Can you send me the diffs between your sb_dsp.c and the one in -stable ?

put them in. But at this point i think the code will not go into
-stable. I got no positive replies except yours, and no feedback
about the plain SB16 operation, and we are too close to a deadline...

	thanks
