Volume issue on Toshiba Satellite pro laptop

Hi All,

I have the above laptop, downloaded Windows 10 - then uninstalled it as it made my machine mega slow.

The + and - buttons to alter the volume no no longer work on the laptop unless you press the FN key.

I went into the control panel to change that, did as I was instructed but I still have to press it to get any volume. I rang Toshiba helpdesk and they couldn't solve the issue either.

Also, the volume has to be turned up to at least 50 to get any sound out as you cannot hear it otherwise. Someone said to do something to the BIOS but i have no idea as I am not tech at all.

Any help would be great as I have tried You Tube and online and not had any luck.

Thanks all.

I set it so that I can press F1 to F12 without holding the Fn key. When I did that then I had to press Fn key to adjust volume with the - + keys that are on the F9 and F10 keys.

Also you may want to open the volume mixer to see if other volume levels are less that the master volume.
