Abstract
A system and method for testing audio components of an optical disc drive. The method of testing the optical disc drive with a removable storage media includes receiving at least one command to test the optical disc drive while the removable storage media is absent and generating an audio tone signal within the optical disc drive in response to receiving the at least one command. The system for implementing the method of testing the optical disc drive with the removable storage media includes a processor, a memory coupled to the processor, and the optical disc drive coupled to the processor and the memory. The optical disc drive is configurable to internally generate an audio tone signal in response to receiving a command during an absence of the removable storage media.
