Comment 9 for bug 1025388

@Jono,

Not sure I'm following. How would the computer know whether your headset mic is broken or not?

As soon as you plug something into that jack, the kernel autoswitches from the internal mic to the headset mic - just as it switches from internal speakers to headphones.

I clearly see there is a use case for a 4-pin headset jack, where you only want to use the headphones and still use the laptop's internal mic, (and likewise, use the headset mic with the internal speakers) but we don't provide a solution for that use case today. If this is what you mean, I guess the report should be a wishlist bug and titled differently.
