so long as the last thing in the chain (i.e. the one that talks to /dev/dsp)
is prepared to:

*either* re-set the AFMT of /dev/dsp
       (depending on the format of the stream presented to it)
*or* leave /dev/dsp AFMT at one setting
       AND do the necessary conversions

everything will be OK.

Of course, there are other solutions - but these would depend on each app
"knowing" that the server only accepts input in format "XXX" which seems
broken to me... (although it has a certain simplicity - if there's a way of
telling the client apps that this is the case).
