Strange noises have started emanating from a speaker in the Boeing Starliner capsule. Listen for yourself and see what you think.
To me it sounds like an audio amplifier whose power supply has gone out of regulation, possibly due to a fading battery. I've encountered a similar phenomenon where a battery powered amplifier or radio will "motorboat" when the amount of current needed to produce a loud sound exceeds what it's power supply can provide. It tries to reproduce a loud sound, causing the battery voltage to sag, causing the amplifier to quiet down, allowing the battery to recover a bit, then it tries again and the cycle keeps repeating.
Or maybe it's something entirely different.
