1. A system for managing audio performance in a vehicle, the system comprising:
an audio unit having one or more speakers and one or more microphones respectively positioned in or around the vehicle, the one or more speakers transmitting an audio signal within the vehicle;
a command unit in communication with the audio unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded;
wherein the audio signal is expected at a specific time with a specific sound and the command unit is adapted to confirm that the audio signal is played within the vehicle as expected based in part on microphone data from the one or more microphones;
wherein the command unit is adapted to:
receive the audio signal through the one or more microphones and determine whether at least one audio quality parameter of the audio signal meets a predefined threshold;
when the at least one audio quality parameter is below the predefined threshold, divide the audio signal into a relatively higher priority group and a relatively lower priority group;
reset and/or reboot the audio unit when the audio signal is in the relatively lower priority group;
disable the audio signal from the relatively lower priority group when the audio signal is in the relatively higher priority group and the microphone data is available; and
switch to a back-up speaker and a back-up microphone when the audio signal is in the relatively higher priority group and the microphone data is not available.
