There are no active mixer devices available. To install mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware.
I try and do this but it is unsuccessful.
Under Device Manager i have a new tab that has a question mark icon named 'Other devices' and the device under it 'Multimedia Audio Controller' which also has a question mark for an icon except with a exclamation mark on it.
I re-installed my Drivers and Bios file from this page which solved the problem before.
Any help would be lovely.
