End to end audio testing prototype on pandaboard
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 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).
The thought here would be to programmatically detect silence via hardwired loopback, then a test tone at a specific frequency(s), then silence again, all in a scriptable command line driven tool.
This blueprint is the second in the series - to port the command line tool for Ubuntu to pandaboard. The application will need to use the alsa-lib for Ubuntu and tinyalsa.
