I was experimenting with dock adapters for our radio after Beth bought a case for her iPhone. While it felt like the connection to between the phone and the radio was solid, and even though audio was playing through the radio properly, something wasn’t quite right. The volume would frequently start ramping up unexpectedly. I raced to bring the volume back down, sometimes having to turn the radio off to keep it from blasting. This was most odd, since I didn’t think the iPhone even controlled the volume. If I switched the audio source to FM radio, so that the iPhone should have no effect, the problem persisted.
Then I heard a chuckle and discovered the true source of my technical difficulties.
