Dell E5510 No audio after driver update

When you open the Sounds properties, do you see anything like this? -- Except yours should say "IDT" instead of "Realtek".

If you right click in the properties box you should see the smaller box where you can select to "show disconnected/disabled devices". Try doing that and see if your devices are there. When you plugged in the usb audio device it might have disconnected the integrated devices.

I plug and unplug.

I add small information:

A)I have second  video connected, but it don't have audio devices.

B)The "Cuffie indipendenti (R.T.C.)" are not connected to the laptop.

C) In the Laptop I just have the integrated speakers and microphone.

D) no sound from all devices

E) buttons on the laptop used to activate/deactivate sounds; increase/decrease volume don't work

Keep the usb headset unchecked when you want the speakers to work. Also uncheck the Independent headphones. It should look something like this:

I try but, in the "Levels" box there is nothing.

Question:

How can i go back to the original drivers?

Filippo,

You should be able to roll back to the previous driver. I don't know the path in 7 but it ought to be something like: go to device manager and find the driver, right click on it and open its properties, select "rollback driver".

********************************************************************************************

Another way is to delete the current driver. Go to

Start>Control Panel>Uninstall a program.

A window will open with a list of software. Find the IDT driver, then right click on it and uninstall it. When you reboot the computer, Windows 7 will install its basic generic audio driver -- not an IDT driver. Your audio should now work. If it still does not work then you might have a problem unrelated to the driver.

Your audio might work with the Windows driver, but some of the audio features might not work, so you might want to install the IDT driver again. You can find links to all of the older IDT drivers (not the current one) for your laptop here.

Jim,

I try with previous driver, but in "levels" i have the same problem.

Do you know if there is some "audio fix " for win7? (Windows 7 Professional

Service Pack 1)

Hello Filippo. I am sorry but I do not know of an audio fix for Windows 7. I haven't seen this problem before.

I would try to install the generic driver that is within Windows. If it did not get installed the way I mentioned above (where I wrote Go to Start>Control Panel>Uninstall a program ...), then you need to clean out all audio driver files from your hard drive. To do that, Go to your hard drive
 c:\dell\drivers\Rxxxxxx   (the x's represent numbers)

Expand all folders and sub-folders there. Delete all folders that have a sub-folder named "WDM". Those will be the audio driver folders and it is safe to delete them.When you restart the computer, Windows should install its own audio driver. If you do not hear audio when that driver is installed, then there is something wrong with Windows as you suspect. It should look something like this -- notice that it does not say "IDT", just "High Definition Audio Device".

Jim, 

I follow your instrution:

windows install "High Definition Audio Device"

but I still have message "no speaker or headphones connected ".

I'll re-install Windows7 .

Thank you

Filippo

Before you do that, did you right click and check "show disabled devices" and "show disconnected devices"?

If no luck there, then run Dell Diagnostics Audio Tests (link below) to make sure the audio hardware is functioning properly. If it is then I am sorry that I couldn't help you get it working again.

I right click , but in all cases i don't have levels, and i some cases the form crashes.

About Dell Diagnostics Audio: it works perfectly.

Thank you

Filippo
