Line in to CPU has not been full tested and needs to be verified.

Top:  Recording, Bottom is source.  The sharp bits on the top are actually in the source as output from an old SB3.  (as a result of the antialiasing filters).

Richard suggested 
arecord -D dac -d 10 -c 2 -f S24_LE -r 44100 /tmp/foo.wav

It creates a file format that audacity & sox don't like.

arecord -D dac -d 10 -c 2 -f S16_LE -r 44100 /tmp/foo.wav

works like a charm.


Tested on r6430 from mysqueezebox.com.
