| 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. |
