|New sound driver release with important signal handling fix.
|The nagging problem with the SB16 hanging or repeating
|sound clips at the end is gone.

|If you want to know more about the fixes that went in see:
|sound/REAMDE.GUSPNP in the tar ball.
Just got a chance to pull it and run it past all the audio tests I can
think of with my SB32. Here's the results:
1) Thanks for the good work on repeating and close() hanging fix! Did
not hear any repeats, and when I allowed audio play apps to finish
playing and terminate normally, I never saw them hang on close().
The only time I saw a hang was when I Ctrl-Ced the app in the middle
of playback (e.g. mpg123); not all the time--sporatically as before.
So as far as this specific problem goes (hanging), this driver is better
than the checked-in version.
2) Load pops on start/end of AU playback. Still there. Don't see this
with the checked-in driver.
3) Attempts to record 16-bit samples gives "Input/Output Error" now instead
of the "Interrupted system call" before. For each failure, I get one of
these in my console:
Sound: DMA (input) timed out - IRQ/DRQ config error?
16-bit record works with the checked-in driver.
4) I think Louis or you mentioned this, but I also see probe output that's
a little strange. Looks fine except for that dma 7 in there. Could this
be related to the DMA error doing 16-bit record?

That's about it. Hope this helps, and thanks for the hard work!
