Updating my sound driver
You can search Google or Yahoo to find the correct internet address of the manufacturer.
If you have a branded computer, go to the computer manufacturer's website.
Once you have the necessary information about your sound device, you can normally obtain appropriate updated drivers specific to your hardware from the internet.
Manufacturers of motherboard sound devices such as Realtek, Sigmatel and Soundmax do not usually provide any driver support to end users.
This often leads to problems such as not being able to select the correct input, or recordings not being made correctly.
These must be replaced with drivers made by the manufacturer of your hardware, so they are correctly matched to that hardware.
If you have a PCI or external soundcard or interface, go to the website of the soundcard manufacturer.
You may need to find out the name, specifications and current driver details for your sound device, so you can update it correctly.
Click on the "Driver" tab to check the driver provider, date and version.
If an update has occurred at any time, the button will be active.
You can click this button to revert the driver to its previous installation.
You can also view a video of the rollback process on Windows Vista later.
If you are reading this because recordings have always worked fine in the past but are now recording incorrectly, or because an input is missing or Audacity is no longer launching properly, an automatic update via Windows Update may just possibly have caused the problem.
