I looked into this on some Linux discussion boards. This appears to be a problem for a lot of people with dual boot systems and I do not think it is limited to just IDT audio. They say that Ubuntu (or whatever version) does something that Windows cannot undo. The most common suggestion is to shut down the laptop, disconnect from AC power, remove the battery, then reconnect power and restart.

See this thread at askubuntu.com.

i don't think now days such Type of hardware are made whose are only Compatible with only OS..  

I agree. The hardware is obviously compatible with either OS, but appears incompatible when using both together. My guess is that either Windows or Linux could fix the incompatibility, but will they?

hmmm But most Pc/Systems whose are affected by This hardware realted issue are using IDT Audio Device...

The person who started the thread I linked you to has an Asus laptop with Realtek audio.

so everytime when i LogOut from Ubuntu i need to do that "REmove Battery "Trick,

Does the trick work? I think a better workaround would be to use a usb audio jack.

i don't think it could be fix in Linux(Due to OpenSource) so i think  DELL should report This Issue To Microsoft , i think Microsoft Will try To Fix It.

If you want to report this problem to Dell, you can contact tech support. If that does not work, you can send a private message to any of the Dell employees who sometimes post on this forum (they have the word Dell in their screen name), and request that they pass on the information to tech support. To send  a private message click on the name, which is a link to their personal page, then click on the link to send a message.

To report it to Microsoft, go to this page and look for "Send us feedback" on the right side.

Audio Jack again Started To work but after 3,4 Restarts again the Same Problem

Install the native windows audio driver. If you have the same issue when using that driver then the fault is not the IDT driver. It is probably intermittent failure of the impedance sensor of the headphone jack -- failing to detect when headphones are plugged in. It's a Windows thing. Non-Windows OS's do not use it so when it fails the symptoms only appear when in Windows.

To install the native audio driver:

1. In Device Manager, right click on the IDT driver to open the context menu.

2. Click "uninstall".

3. Check the box "Delete the driver software for this device". Don't skip this step.

4. Restart the laptop. Go back to the Device Manager and check the Sound...Controllers. If the IDT driver is still there, repeat the procedure until it no longer appears. When all versions of it have been removed from your hard drive, Windows will replace it with its native Windows driver named "High Definition Audio Device".

When i Restart my Pc 3,4 Times Audio Jack Stop Working and again Some restarts it starting to Work Again, when it Work, if i in/out Headphone Jack more Than 1000 times it works fine, but when Jack Won't Work if in/out headphone Jack More than 1000 times it won't work. So Why that sensor won't stop WHen my audio jack is working fine, means if audio jack works when windows start Sensor won't fail, No atter how many times i In/out Jack but when sensor fails , it stays Fails?? Why is That , i Don't Get It... emoticon.Sad.title emoticon.TongueTied.title
And my Internal Microphone won't work when i switched to native windows drivers... Now,How i Solve This.... ?? emoticon.Crying.title

It could be intermittent failure. I don't have an explanation, but if you have the same issue with the native driver then the fault is not with the IDT driver. If the fault is not the IDT driver and you don't have the problem in Linux, then all of that strongly suggests that the sensor is failing.

And my Internal Microphone won't work when i switched to native windows drivers... Now,How i Solve This.... ?? 

The point of using the native driver is to help diagnose the issue. After you are finished testing with it re-install your IDT audio driver.

Jack is bot working... now i again re-install drivers and jack started to work again??? why is  that??

I cannot explain it. I said it is "probably" hardware failure because the symptoms "suggest" that, but maybe it isn't. Sensor failure creates software failure so it is all mixed up and really tough to diagnose, and frankly sometimes requires guesswork.

Look, I assume that the jack worked okay when the laptop was new, and this is a recent problem that has developed? In that case perform a system recovery and test the jack immediately afterward, before allowing Windows updates (security updates are okay) or installing programs. The recovery will fix all software issues and make the jack work like it did when the laptop was shipped from the factory, and the only reason it would not work would be due to hardware failure.

The only other way to prove or disprove hardware failure is to replace the jack with a known working one.


The only other reason I can think of for the jack to not work is if it is configured to be the "communication" headphones. With that configuration regular audio would continue to go to the speakers and only "communication" audio would go to the jack. When the jack does not work, is sound to the speakers cut off? Or does audio still go to the speakers?


Looks Like IDT release it's Hardware And Software Without Testing It...

If it were due to the IDT audio driver, then the problem would go away when you use the native driver. Also all other laptops with your IDT driver would have the same issue.

Concerning the hardware, as far I know IDT only supplies the audio chip, not the jacks.


And 2nd is their any way to disable that sensor or whatever it is , like Ubuntu ... ??

There could be a hack that somebody has come up with, but I don't know of any. A workaround would be to get a cheap little usb audio jack.

The only fix I can suggest right now is to perform a system recovery, and if that does not fix it then it is because of hardware failure.

Your initial tests suggest that a system recovery fixes the problem. I would do the recovery again  and test the headphone jack for a longer period of time -- maybe a couple of weeks. If no symptoms show up then it looks like the hardware and software are both working properly.

Then if you boot into Ubuntu again and subsequently the jack again fails to work in Windows, it would seem that the jack is compatible with either Linux OS or Windows, but not with both. In that case, if you have to continue to use both OS's on your laptop, you might have to get a usb audio jack if you want to continue to use the headphone jack with Windows.

i GooGle My Problem and i Found that alot of people who have IDT chipset has Smilar Issue..

If a lot of people find their headphone jack does not work in Windows right after using Linux, then it looks like a systemic bug. Maybe someone on a Linux discussion board would have some idea of how using Linux could affect Windows like that. I have no idea.
