Starliner's speaker began emitting strange sonar noises on Saturday
Briefly

Amidst the routine operations aboard the International Space Station, astronaut Butch Wilmore encountered an unusual noise in the Starliner spacecraft, prompting an investigation.
Mission Control engaged promptly to diagnose the auditory anomaly, linking to the spacecraft and hearing a distinctive ping that resembled sonar, which baffled both astronauts and controllers.
The Starliner spacecraft separates from a radio frequency communication system used in transit but relies on a hardline setup post-docking, raising questions about audio irregularities.
Wilmore's light-hearted response to the noise highlighted the camaraderie with Mission Control, as he playfully invited them to deduce the source of the strange sonar-like sound.
