![]() ![]() The latest working (official) version I've been able to find is. Also, there seems to be two name variants of the same version every time: 5xxxx and 6xxxxĪll I know is that, according to the documentation, my computer (XPS 410) uses a STAC9227 codec. All of these groups contain versions that have little overlap and every listing is different for every site. Apparantly there's a distinguishing between Sigmatel HD audio codec and IDT HD audio codec, Sigmatel 92xx codec, there's an Intel download page which offers certain other versions for specific main boards and I also found some modded drivers. With this solution came another 'problem', as I found out that the the Sigmatel/IDT drivers are remarkably fragmented and all over the place. ![]() It all worked well when I installed a Sigmatel/IDT driver. Because I was using the a default windows driver for my (default integrated) soundcard, this option wasn't available in the recording section. Even if Vista can tell you've got 5.1/7.1 compatible hardware, it won't automagically change the defaults - you have to make that adjustment yourself.It all started when I discovered (after all those years) that recording the sound from your computer doesn't require a cable to connect the output with the mic. Hell, I wouldn't even buy a mobo if it had/has Sigmatel audio onboard anymore, it's just not worth the hassles.Īs the post above hints at, you do need to change the speaker settings in Vista to adjust from the "default" of 2.0/2.1 speakers to what you actually have to get the proper output. Realtek onboard audio is a snap, I can't understand why the Sigmatel crap is so difficult. I've had to use this process on hundreds of machines with Sigamtel onboard audio. I don't know why Intel and Microsoft decided to create that stupid UAA crap - well, I understand why, I just wish they'd done a much better job of it and supplied the UAA driver to the OEMs so they could include it in their driver installation routines and save the end users a shitload of hassles.Īnywho, install the UAA driver first (if you can locate it, of course) and then the Sigmatel drivers and hope for the best. ![]() Once that driver is in place, it'll be there and ready to kick in when the actual audio driver for the branded audio card/chip is in place, which you would acquire either from Sigmatel (they have 'em, they're just tough as hell to locate on the website), or the OEM maker of the mobo in question.Īfter that Intel/Microsoft UAA driver is installed (it'll still show the yellow exclamation point in Device Manager, mind you), and then installing the proper audio driver, after that's done and the system reboots (reboot even if it doesn't prompt you to do so), you should have working audio afterward.ĭo NOT install the audio driver first, if you make that attempt it'll never work right and the only solution I've ever found that was 100% reliable in such a situation is to completely start over from scratch. All download links are listed below on page. It is supported on physical defects for this. Here you can download sigmatel stac9227x5 audio driver download for Windows. The first is that rather ridiculous Intel/Microsoft UAA "high definition audio driver" that you have to get installed first - that's the key here, it must be installed before the actual sound card/chip driver which is where most people get screwed up. Open Device Manager and then click 'Infrared devices' and than choose 'SigmaTel USB-IrDA Dongle'. These days, onboard video primarily using those shitty Sigmatel chips - sorry, but it's the truth, they are absolute shit - requires two sets of drivers. ![]()
