Stephen Borrill reminded me that I'd never contributed the 16-bit sound 
driver that I have for the RISC PC.

The reason for not doing so is that the code is a bit of a hack 
(understatement of the month here); so instead of installing it directly, 
I've uploaded a patch to the ftp site.

You can find the patch in

pub/NeBSD/arch/acorn32/misc/

the pertinent files being README-sound16 and sound16

Have fun.  If anyone has time to try this on an A5000, or a machine with 
8-bit DACs I'd be interested in hearing how you get on.  (If the bootparam 
sound16 is not set, then it should default back to the old behaviour).
