Sigmatel Audio Drivers
Nov 12, 2009
After a clean install of Windows 7 from Vista 64 bit , all went perfect except for the audio drivers. After a few weeks Windows 7 was saying that the sigmatel audio driver installed was not working. Sigmatel is now actaully IDT. Any of the so called updated drives from sigmatel or IDT will not install. So just delete any installed audio drives in Device manager and let windows install the drives upon rebooting, they work perfectly and they are the most recent drivers i could find anywhere for the High Definition codec.

Have a tablet PC that I just installed Seven onto. Even though it's an old box, Windows update found nearly all of the drivers. The one it didn't find is for the AC97 Sigmatel audio.
So, I grabbed the drivers I used for Vista (they're actually XP drivers) and tried to install them. Did this again and again, using different compatibility modes every time. Got no indications of failure, but never worked, either.
Tried removing the device and having Windows Update search for a driver. No luck.
Tried installing driver from selecting from list. Only Sigmatel driver in the list is for HD -- which I don't have.
Even tried the MS WDM driver -- and it refused to install it.
I read in another thread that there are supposedly generic AC97 drivers --but I can't figure out how to install them.
The relevant driver files from Vista are STAC97.sys and staco.dll -- which tells me this is a STACS AC97 audio chip. But I just can't figure out how to get a driver installed.

Okay I have an inspiron 1721 with Win 7 Ultimate installed on it. Everything works fairly well on it except I have no audio. It says no device installed, and I have tried all types of different versions, under compatibility mode, admin, and ect... when I try to install the drivers it says things along the line of "Device object not present, quite and restart system and try again."
I only had sounds once, and it was pure crazy loud static.
Update STILL TROUBLE: Audio drivers installed. I uninstalled what I found and it re-installed and did the same weird noise issues. Then when I rebooted, it shows no audio output device installed.

I have an older P4 2.8ghz Dell Dimension 3100 that currently has Windows 7 installed. Apparently the driver is the Sigmatel 97xx C-Major audio according to support.dell.com - the first thing I tried was the Windows Vista driver listed on Dell's site. Unfortunately that did not work. The driver appears to be installed and I have a sound device however I have no output through the speakers. I'm sure it is a driver related issue.
The device enabled, the speakers work and are hooked up properly. Any ideas where I can find a Windows 7 driver for the Dimension 3100 using the onboard Sigmatel 97XX?

I previously had a stuttering issue on "only" music playback with my SigmaTel High Definition CODEC, but after rolling back my drivers to the default Microsoft tones, the audio stuttering disappeared.
Since I have never used Microsoft audio drivers, are they of the same quality as the SigmaTel's? My current version is: 6.1.7600.16385
Any issues with keeping this default Microsoft HD Audio driver?

I have A Dell XPS 420 with a Sigmatel Stac92XX C-Major HD Audio Driver and I was running Windows Vista X64 SP1 and everything was working fine.
I just recently installed Windows 7 RT Build 7100 and the Generic High Definition Audio Device Driver Installed and all types of media play, but it's causing a crackling sound in my audio and not only that it actually corrupts the file so if I were to play a MP4 on my XBOX 360 it also has the crackling noise even if the file was originally fine.
I don't know the last Sigmatel Driver that was on my Vista Build but I tried a few of them and even tried in Vista install mode but none of them work & I tried all the codecs packs that I always install and still nothing.
What should I do and is this a driver problem that's causing the crackling noise and corrupting my files or is their something else to this please help because it's driving me crazy?

I'm having trouble tacking down an audio driver for my Dell Inspiron E1705/9400. It has a Sigmatel 9200 HD Audio Codec. As Indicated from device manager
HDAUDIOFUNC_01&VEN_8384&DEV_7690&SUBSYS_102801CD&REV_1022
VEN 8384 - Sigmatel
DEV 7690 -9200 HD Audio Codec
SUBSYS 102801 - Dell
The audio card is able to output sound however while playing back any prolonged audio, ie music, the playback is unacceptably interrupted with digital artifacts such as skips and pops. This behavior is experienced using a variety of drivers. All drivers have been uninstalled using device manager and then the system has been rebooted before installing the next driver. Also all of the other dell recommended drivers have been installed without a hitch. Finally all windows patches are up to date.I started with the driver provided by Microsoft and continued to try the recommended driver from dell, R171788. I have also tried the following additional driver packages from dell, R108276, R147073, and R171789.
Additional Information:
OS: Windows 7 x86 Home Premium
Dell Service Tag: BSCDK91

I have a Sony Vaio VGC-RC110G and installed Windows 7 RC 32 bit and it went smoothly 'cept for 2 missing drivers. The main one is the sound device as it is NOT being read. I can't get any sound. I spent several hours on the net looking for a compatiable driver, and alot of people ran into trouble with the SigmaTel High Definition Audio Codec when they upgraded to Vista. Tested a bunch of drivers (from Sony site and even updated sound drivers from Dell) and none worked.
Even downloaded some program called detective driver to help me find compatiable driver but I'd have to pay $30 to activate the program. I would but Im afraid it might not find it.

Dell Inspiron 9400 laptop, dual boot of XP Home and Windows 7, install of public beta went really well. In Windows 7 I have a volume icon in task bar, but no audio output I can hear... Windows 7 is using the digital output with spidf, which I can't use, it shows no other option. I can't seem to install the original drivers (from Dell, for XP), they fail (sez they're not the right drivers for my hardware, even though I tried installing as Administrator).
In XP, device manager reports the SigmaTel High Definition Audio CODEC, what am I missing here? I think I'm needing to install the "legacy audio" drivers?

I have been trying for a week now to get my audio card working on my Dell Inspiron 1721. I did the update to 7 and then lost audio, I found a driver that would install, but then the audio was pure digital garbage.
I have yet to find a driver that will work. I went to SigmaTel homepage but that didn't help either.
I upgraded to 7 64bit from a 32 bit version of Vista. Full program, not the upgrade. I am ready to dump 7 and go back to Vista.

I installed Windows 7 ultimate and since I have the forbidden red x over my speaker in the toolbar. I click on it and I get the no audio output installed. If I go to device manager my sound card show up fine. I thought I would try to update the driver to see if that would fix it.
Everytime I try to update it searches and finds audio software but when it begins to download an error pops up saying something to the effect of " hardware is not connected to the computer" or something like that. How do I fix this issue and get my sound back??

When I am listening to music, sometimes the sound is distorted for a short period of time.
This also happens if I return from a break, and my display turns on when I move the mouse (while the music is still playing).
If I just listen to music, and don't do other things, it does not occur as far as I tested.

I'm running Windows 7 32 bit and I just noticed that all my drivers for the USB controllers, Audio/Sound devices and the Networking internet (Broadcom Netxtreme Drivers) have all died. They indicate that a Code 39 is the problem. I tried to load some of the drivers but it wouldn't allow them to install. I did a last known configuration attempt, no results. Did a system restore and it gave me an error message saying it didn't restore properly. I am trying to get the drivers online, burn them to a disk and load them. I have no internet access on that PC and the USB ports obviously don't work. I can get drivers on this PC online. Some I can't find. I did the uninstall driver, disable, all the usual for this problem. I am stumped. Any recovery attempts produce nil results. Thanks to Microsoft, I have no installation disc to do a new install or a backup image.

problem I'm having is that the on-board audio will not install regardless of what I do, let windows solve the issue, install the (apparently) compatible driver from the Gigabyte website via it's exe or manually from the same source.
I'm a little short on time at the moment so if any more info is required (system or other) please ask but I'm at a loss as to what to do. Despite oodles of googling If I can't find a solution I will just buy a new soundcard but this is a last resort.

My sound is working but "line in" and stuff wont show up in sound. So I have sound but no mic. The driver says its a Microsoft driver. The sigmatel audio drivers I tried using were all distorted when I installed them as in the sound would work and everything would show up in Sound but was messed up. Its obviously the wrong driver so I uninstalled it and put the "Microsoft" one back.

in Windows 7 Realtek HD Audio Drivers
I think I have found a solution to this.
I recently had problems my self.
First you have to install this, from Intel: Intel® Desktop Board D910GLDW Audio: Realtek* ALCxxx Driver
Second, install the latest drivers from Realtek, R2.22. I uploaded the zip file to filefront, as their ftp server is running by mouse power. Vista_R222.zip Download File
I hope it will work. for you. I had a lot of trouble finding the solution. Everything has to do with Intel's high definition codec that for some reason Realtek choose not to include in their driver packages.

I'd just like to tell anyone who has a sound card based off the emu10k1 chipset that Creative had discontinued driver support for the cards as of Vista. They release new drivers but a lot of the sound was botched intentionally (or so the rumors go).
That's why if you install propriatery drivers you get too much bass or crackeling? If that sounds familiar you know what I'm talking about, well then you might want to try out the KX Audio drivers (both 32bit and 64bit). They are much more configurable than the original Creative/Windows drivers and work very well.
I have used them both for 32bit and 64bit, I posted a link in the other drivers section but I'm going to post this here as well, if you want to move my other link I'm sorry for posting it in the section I did. Anyways I'm just typing this so people will know that Creative has no intentions of ever picking up support for the emu10k1 chipset.
Full list of supported drivers (note 64bit is BETA support may be limited):
kX Project: Knowledgebase: kX Soundblaster Compatibility List
Known issue with 64bit is the kmixer works in Vista compat, but I'm fine with that because audio runs 100% smooth. Also it has autodetection for the audio jacks wich is VERY glitchy so I would recomend Wave Out 4/5 for stereo on 64 bit (green next to black), and plug it in before you reboot.
Once you boot if you change the plugs it might lock up, hopefully that changes on the newer builds. You might be able to get surround working, I didn't test it and don't know what Wave Out it is so have fun if you test it.

I have an old Auzentech X-Plosion Cinema sound card and Realtek audio connections on my P8P67 motherboard.
Would there be any problems if I installed drivers for both and switched between them?

Apart from the manager where you can manage your connection is there any stability or sound quality improvement. It definately fixes my Unreal engine 3 BSOD's, but why could that be?
