I thought about asking this back in your Audioscope post, why do you need this line?
Code:
printf "\x52\x49\x46\x46\x64\x1F\x00\x00\x57\x41\x56\x45\x66\x6D\x74\x20\x10\x00\x00\x00\x01\x00\x01\x00\x40\x1F\x00\x00\x40\x1F\x00\x00\x01\x00\x08\x00\x64\x61\x74\x61\x40\x1F\x00\x00" >> /tmp/squarewave.wav

Thanks

AudioScope...

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included.
