PURPOSE:
Check that system detects a microphone being plugged in
STEPS:
1. Prepare a microphone with a standard 3.5mm jack
2. Locate the microphone jack on the device under test.
Keep in mind that it may be shared with the headphone jack.
3. Run the test (you have 30 seconds from now on)
4. Plug the microphone into the appropriate jack
5. Unplug the device for subsequent tests.
VERIFICATION:
Verification is automatic, no action is required.
The test times out after 30 seconds (and fails in that case).
