No signal picked from external MIC jack 3.5 – Inspiron 1720 – Vista Business - Sigmatel STAC 92xxHD
Hi,
I am having issues getting my laptop to pick signal from the 3.5mm jack mic/line-in
I am using Sigmatel driver version 6.10.0.5614
I am using Adobe Audition 3.0 to record voice,
When I plug in the microphone in the 3.5mm jack (right hand side), a window pops up, I choose microphone, and then I know can record with no problems. The next time I use it (24 hours later, or it could be 5 mins later), I plug in the microphone but this window doesn’t pop up (and I didn’t check the box that says “don’t show me this windows again” the previous time so the window should show up), and that’s when I know I’m doomed.
It doesn’t matter what I change on the Recording configuration on Vista, the only way I get it to work again is by uninstalling the drivers, rebooting, Vista picks the same driver again and installs it, it asks me for a 2 reboot and it works again once or twice. Then I gotta do the same procedure, over and over.
I know it is not the Microphone because I tried 3 different working ones.I know it’s not Adobe Audition because it behaves the same way with Sony Sound Forge 9 and because the sound option in Vista has these vertical bars moving up and down when it detects sound coming from if the 3.5mm jack so I can see when it’s receiving signal or not.
I already read the posting:
“Dell ships its notebook computers with the ability to monitor the input jack turned off. This means that you can't hear an audio signal routed through the mic or line-in jack even though you can record the audio and hear it when you play back the recording”
http://dellcommunity.com/supportforums/board/message?board.id=insp_audio&message.id=29912
And I wished it fixed it but that is not my case, because it’s not about hearing or not an audio signal routed through the mic/line-in jack, it really didn’t pick any signal, I can’t hear anything when I play back what I recorded. Still, I added that registry key, I see that box saying input monitor, I unmuted it, and of course it made no difference.
To be more accurate, when this happens, Vista senses a tiny tiny sound from the mic, even though the booster and recording volume is all the way up the max and I am screaming with the mic right next to my mouth.
-Is there anything in the registry that I can verify?
-Should I install the XP drivers for that sound card (like some users suggested in other posting?
-Is anybody experiencing the same issue?
This laptop belongs to a priest who records his classes every week and I am helping him with this setup but he won’t know how to uninstall the driver everytime he has a class.
Is Dell aware of this issue? I mean, the forum is loaded postings about sound problems with the Inspiron 1720 w/ Sigmatel STAC 92xxHD, is there anything I can do? Or do I have to face that I made a mistake suggesting the priest to buy a Dell?
I apologize if I sound too abrupt, I am just SO frustrated!!!!
THANK YOU☺

There have been several posts about the problem, but I didn't keep track of the models. I don't remember seeing a solution and I don't know if Dell is aware.
The Sigmatel audio driver you are using, R171786 (v.6.10.0.5614 ) has a note under "Fixes & enhancements" that says it "Improves external Mic channel". Don't know what it was supposed to fix.

You could contact tech support or post on Dell's blog called Direct2Dell. I don't know how you get a message to the engineers who designed the problem into the computer.
