I have the full Creator 2012 Pro ... and enough said about the earlier version (Creator 10) that I had peviously loaded! No additional codecs have been added (to my knowledge), and it's not a case of low or muted audio settings in Windows...
The audio on this laptop is a mix of Intel HD and Conexant SmartAudio HD .... not sure how the 2 are supposed to interact. I understand that the 2 videos (Intel HD Graphics, and the nVIDIA 310M) function with the Intel first, and the nVIDIA kicks in when demand requires it.
The drivers are now up to date, with no improvement to my original problem. So, I'll take your advice and try the Revo uninstaller. That'll be a job for tomorrow.
Are you suggesting that I use Revo to uninstall Creator 2012 Pro (and any residual stuff), rather than Creator's own uninstall first followed by Revo?
Something I have noticed this time round is that in my registry settings, there is no Sonic folder in the HKEY_LOCAL_MACHINE directory .... I'm sure there was before I uninstalled Creator 2012, so should I be worried?! There are Roxio, SmartSound and Sonic ones in the HKEY_CURRENT_USER folder.
