Hi! I have a year old Inspiron 1525 with Vista and it seems to be having problems with the Line-In mic - the built in microphone array is working fine, but when I go to plug in a headset, the mic on it does not work. I have checked the volume and able/disable on both the headset and the computer, switched the default recording device from the array to the headset, etc. Nothing seems to work. It won't recognize any sound coming through that jack.
The driver seems to be fine, as the array is on the same driver.
Any ideas or tests I can do?
Did you ever solve this problem? I'm having the same issue. I just installed the latest driver (SIGMATEL STAC 92XX C-Major HD Audio 18.104.22.16866, A03) but it still does not work.Thanks,Marcus
