Possible Causes of Audio Device Driver Issues

Audio outputs are very important to let PC users like you enjoy movies, games, songs, and even the slightest beep from chat messages or pointer clicks that will make your computer experience worthwhile. On the other hand, many PC users are being bothered by audio device problems, and most of them mentioned in computer related forum threads that they encountered issues such as distorted sounds, on-and-off audio output, and having a soundless computer.

In most cases, PC users reported that such problems are due to the required audio driver of the onboard audio device or sound card such as IDT or Sigmatel High Definition Audio CODEC, but there are different cases when they do encounter such issue. Some PC user mentioned that they encountered this problem all of a sudden, while others reported that they experience audio device problem after they had undergone some changes on their computer (OS reinstallation/upgrade/downgrade, program installation, etc).

Whatever the case, most PC users recognized that the problem that they have encountered is device driver related. For example, a PC user who just upgraded her OS to Windows 7 mentioned that at first, Windows is able to detect his onboard sound device, but there is no audio output, and then afterwards, he mentioned that it turns out that Windows cannot detect his sound device anymore. Another PC user who just reinstalled Windows XP on his friend’s laptop mentioned that after the OS reinstallation, there is no audio output at all. PC users who have old OS version (XP, Vista, etc) also encountered similar audio problems after upgrading their OS to Windows 7.

For such hardware device problems, it is very obvious that the recommended action is to install the required driver such as SigmaTel or IDT audio driver, but you must make sure that the driver that you are going to install is the latest updated version, since some driver related issues can also be due to out-of-date drivers. On the other hand, before proceeding with the driver installation, you must make sure that your problem is driver related.
