It does seem counterintuitive, doesn't it? The problem seems to have to do with the microphone signal - the input, not the output. The new firmware changed the way the Mogul responds to what it sees there. Keep in mind that the Mogul only sends audio to the output if it senses that there is something connected there to receive it. Otherwise, the audio goes to the internal speaker. So something changed in the logic that triggers the audio port to become enabled. And certain adapters still work fine, while others no longer work at all.
One person figured out that if you can disconnect pin "1" on the problem adapters, they begin to work. So it appears to have to do with that signal. And that's the one that carries the microphone input from a wired headset. Unfortunately, disconnecting that pin can be easier said than done.
