Was listening to audio of today's flights and you seemed to be having trouble with the A/P aural warning on disengage.
If I may ! If you are using the PMDG B737 for FSX which I believe you we're, you press the A/P disengage button once on the control yoke to disengage the autopilot then again to cancel the aural warning.
If you have already figured this out, disregard this message.

PS. Today for you in the states would be Wednesday 31st. Flight KSAN to KSFO
