I just upgraded to Windows 7 Ultimate 32bit from Windows XP Professional SP3. I've got most of my devices (printer, scanner, etc.) to work but alas no sound.
I installed Speccy and found that I have a "High Definition Audio Device" soundcard, which lead me to install the 184.108.40.20613 version of Realtek High Definition Audio Driver.
However that hasn't solved the problem. Thanks for any help in advance.
