OKAY GUYS HERE'S THE FIX ... I know many of you probably found and tried that wave mapper trick and it didn't work .. well so did I ... but I happened back to the page and tried what our friend suggested at the end of his blog... and let me tell you the sound was back immediately
FYI- I did search for the msacm32.drv on my drive but it wasn't to be found so I copied it from another computer and pasted it into my system 32 folder and oh man! instantaneously....I heard that windows sound... clidked over to youtube and bingo bango.. oh yeah baby! FOR YOUR LISTENING ENJOYMENT....THIS WORKS!
Also ensure and verify that the msacm32.drv driver file is existing in C:\Windows\System32 folder. If the file is missing in that location, search for other copy of msacm32.drv in the computer, or copy that file from another system.
courtesy of... bless him! the man's a genius!
