Why does audio rapidly repeat itself when a computer crashes?
At a high level, sound cards playback sound by reading digital data from a buffer and converting it into an analog signal to transmit to the speaker. When a normal stream of audio is being played back, its data is written into the buffer as a stream so there's no hops or skips – as the digital au…
The Short Answer
At a high level, sound cards playback sound by reading digital data from a buffer and converting it into an analog signal to transmit to the speaker. When a normal stream of audio is being played back, its data is written into the buffer as a stream so there's no hops or skips – as the digital audio converter scans back and forth over the buffer, the buffer data is overwritten as its being played. If the audio controller crashes but the hardware is still going strong, it begins to simply replay what happened to be in the buffer at the point of the crash, causing the effect you describe. The audio will fully stop if the OS can catch the program going unresponsive and eject it from memory, which frees the audio controller.
