Question about HP (400745-001) Sound Card
If even the Windows 7 driver for the sound card did not fix it, try to uninstall the audio driver, then let Windows try to detect and install a native driver if available. Then click START, type services.msc in the Search box, then click Services.msc from the results. From there, look for the Windows Audio service, double-click it and make sure the Startup Type is set to Automatic and click the Start button. Restart the computer, open the audio properties, make sure the correct Playback device is selected. If you are using internal speakers for a laptop or external speakers for desktops, select Speakers/Headphones, click Set Default. Then test the audio of your system. Hope this helps.
