> Hi Raymond, David. > >> >> available state of mic jack should be yes after the mic is plugged > > Agreed, but on this model it feels like there's a mix-up between both mics: "Internal Microphone" is basically unusable and full of noise (like an unplugged non-internal microphone), and "Microphone" works fine as if always plugged (like an internal microphone), though pulse reports the contrary. do you mean this patch still don't fix the internal mic ? <a href="http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=ffe535edb9a9c5b4d5fe03dfa3d89a1495580f1b">http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=ffe535edb9a9c5b4d5fe03dfa3d89a1495580f1b</a> do the value of "mic jack" kcontrol become true after you plug the mic ?
