It certainly seems way more trouble than it's worth: as soon as the on board mic is used the jack detection will get confused as it'll see it. Of course, the internal mic is actually plugged in to a header on the main board so it may be absent too (I believe a lot of units were shipped without a case...) which means detecting the internal mic might actually be useful :) > Either way, I suppose I should add two explicit mic widgets, each directly > driving the appropriate GPIO, so that the user can select which mic(s) > actually get used for capture. > Does that sound reasonable? I think that's the best approach. If someone wants to do mic detection they can always add it later. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
