Test that the sound from media files can be heard by recording from mic in.
|
|
Each audio channel is tested independently and currently there is no accurate
|
|
comparison with the input data. Instead the test passes when
|
|
a) the silent signal is sufficiently weak and (TODO: rohitbm@chromium.org)
|
|
b) the captured audio from each media replay is sufficiently loud.
|
|
|
|
NOTE: For this test to pass you need to have the line out looped back to mic-in.
|
|
This can be through a 3.5mm male-to-male cable or a loopback dongle depending on
|
|
your device.
