end-to-end audio testing (jacks)

we are looking at landing more and more full stack test cases for our
automated board support status tracking efforts.
While for some hardware ports it's hard to test whether a port really gets a
proper signal etc, we feel for audio this might be
relatively straight forward: we got the idea that we could connect a cable
from jack out to jack in in the lab and then have
a testcase that plays something using aplay and checks that he gets proper
input/signal on the jack in.
This could be done on alsa level and later pa level (for ubuntu).
A more advanced idea that came up when discussing options was to use
opensource speech recognition like sphinx to even
go one step further and see if the output we produce yields roughly the same
input. For that we could play one or two words,
use speech recognition to parse it and check if the resulting text is
What do you think?
Would MMWG be able to take experimenting and implementing such end-to-end
audio test into their 11.10 work list?
Thanks for your support!
