For two nights now (different times) weird sounds have been coming from the speaker of my G4. I shut down all programs and I heard Heavy Metal music. I put the computer to sleep and it stopped. I woke it up and it came back. Later it was music from a different genre. No announcer so I don't know if it's local university radio or some body broadcasting from their basement, either way there is no antenna, bluetooth or wireless hardware connected. An iMac is networked within five feet and it's quiet. It has not been moved or altered for weeks and this just started.
Outside of a dog, a book is a man's best friend. Inside of a dog it's too dark to read.
