[RFC] DMAsound 2.4.0-tx => 2.2.17 back-port.

Hi Henry,

The rate, mode and so is all done in software by the dmasound driver.  The
only hardware assists are: different sample rates (where supported) and
LE/BE swapping.

Oops, my stest instructions were not good enough - you need to tell stest
what the format of the file is:  **It does not look at *any* header
information**

./stest with no params will give you all the options.

./stest -b16 -s -B -r 44100 -f  AFMT_S16_LE_S_44K.wav

(IIRC) would be right here...

and so on...

Sorry, I'll update the web page to point this out.

ciao,
Iain
