I upgraded an older (circa 2005) Inspiron 9300 laptop from XP to Windows 8 (and later 8.1), but I lost all sound. I looked at the Device Manager and there is no driver. I looked for a new driver to the Multimedia Audio Controller, but it doesn't find anything with the automatic search. I tried looking and can't find a driver for this laptop and Windows 8 or 8.1, and trying to figure out my next steps. Please let me know if you have any ideas.
