Excerpt from general trouble shooting: "Audio Circuit: no sound on speaker?...try extension speaker.... Check for receive at the volume control with a signal tracer. Check audio IC operation with the hum injection test--a finger on each leg of the audio IC (one at a time) should make a loud hum on the speaker (courtesy of the power company) when the input pin is touched."
