That leads me to ask.Is there an update like KB2962407 for Windows 7 that would be under a different KB number? I've tried other things including rolling back the driver, reinstalling the updated driver, deleting the driver first and then reinstalling the driver, turning off 'audio enhancement' in the SRS control panel, and running the 'playback audio' troubleshooter. I also Googled that update and found that it only applies to Windows 8 and Windows Server 2012, not for WIndows 7.
I've tried looking for the KB2962407 update to see if it's been installed, but it's not. I've read through this entire thread and can't find anything that has worked. I have installed the most up to date IDT driver that's listed on HP's site.
I'm having this same problem on an HP folio 9470m with Windows 7 Enterprise 32-bit installed.
