Test case is ran by writting a command string into this file\n\
Format of command string depends on the test case you intend to run\n\
Quit audio_test app: type echo \"quit\" > /tmp/audio_test\n\
If there are test cases still in executing stage, audio_test exits upon \n\
all test cases finishes. \n\
Audio_test app supports concurrency. If one wishes to issue playback \n\
control command to a particular test case(e.g play mp3), one must specify \n\
an id by giving argument -id=xxx (e.g 123 must be a number) so audio_test \n\
knows how to dispatch control command to a particular test case. \n\
Issue control command: echo \"control_cmd -id=xxx -cmd=xxx\" > /tmp/audio_test \n\
command can be pause, flush, and etc. \n\
Format of command string is test case specific. Run audio_test -format test_case \n\
to see the format of command string for the desired test case. \n";
