I recently ran Advanced Driver Update to check and updated my audio driver (IDT High Definition Audio Codec) on my Windows 7 laptop. However, after the update, every time I boot up the computer, there is no audio output. I checked the volume control options and they are all fine, showing "all devices are playing sound". But there is no sound. Even the 'test sound' option does not play any audio, although the computer says that it is working fine. I read some posts on this forum and came across an answer - to uninstall the current driver from Device Manager, and manually install IDT HD Audio Driver for Windows. This works and I am able to get back the sound. However, I have to do this every time I start my computer after shutting it down, and this is proving cumbersome. Can somebody please help me with this and suggest a solution? Thanks.
