Windows 7: Dell Inspiron 1420 Audio Problems

DellUser2010 · 11 Jan 2010

I recently installed all the necessary drivers (High Definition Audio Device) so my computer is certainly up to date. I know how to use this and have done this successfully before, well a friend did for me. I can't seem to find the right driver now or its corrupted, not sure. This problem re-occurred when I reinstalled Windows 7. Maybe someone here can help me, as I've never posted to any forum before. The audio plays just find through headphones, but the computer speakers don't work. This can't be a hardware issue, I'm almost certain it is an issue with the drivers. I found the driver at the Dell support site, and it still doesn't work. Please help!!!

open your audio properties and set your speakers for default playback device...Welcome to seven forums....

Maybe I didn't do this correctly but it still hasn't changed. I believe these are the problems now, i just can't fix them via Windows Update or whatever.

Open your device manager and make sure there are no yellow exclamation marks showing up... if there are, take a screenshot and post it...

Does anyone know how I can go about re-installing my base system device under the audio section of the device manager?

Most Dell's require the Dell (integrated audio) sound drivers to work correctly. I've seen a lot of users, on the Dell users forum, that have tried non-Dell drivers and many either do not work or do not work correctly.
The Dell driver downloads are here: Drivers & Downloads=
There is one SigmaTel Vista 32 bit driver, which should work OK on Win 7 32 bit. Dell does not support Windows 7 on this model so you are stuck with the Dell Vista driver, or a non-Dell driver that may not work correctly.

In addition to the sound driver, there are two Chipset Drivers listed. The chipset drivers are one of the most often skipped items on an install and most install problems can be traced back to not having the chipset drivers installed or installed in the correct sequence. For most Dell's the install sequence is (1) Install Windows (2) Install Dell Laptops System Software (on applicable models), (3) Install Chipset Drivers (4) Install Device Drivers including Sound, Video, Ethernet, etc.

I can't seem to download any drivers from the Dell site because I keep getting this error message...

I had the same challenge... Here is the solution that helped me out:

Quote:

The symptom
Following a fresh install of Windows 7 (I haven't tried an in place upgrade as I just don't trust 'em !) the OS sees the Sigmatel device and reports it to be working, but the sound just doesn't work. Any attempt to download and install the latest Vista drivers also fails to cure the issue.

The fix
Download the latest x32 or x64 (as appropriate for your computer) Vista driver from the Dell website and leave the EXE in a folder somewhere
Or get them direct from us, click for the 32 bit driver or for the 64 bit driver
Right click computer, and choose manage, then device manager
In the Sound, Video and Game controller group you will see a device called "Windows High Defintion" - delete this by selecting and pressing delete
Now having removed this device from your system you should run the Dell Sigmatel Driver EXE you downloaded previously
Your system will prompt for a restart upon install
When you restart you will get the reassuring sound of the Windows 7 start up tune and all will now be well !

Hope this helps someone, took me an hour today to figure it out.
