Acer Iconia W700 volume button problem.

I have a Acer Iconia W700(I5 core) after the windows 8.1 update it was very slow and buggy but it has been fixed and running fast again.

But i have another problem my volume button is not putting the volume up or down anymore.

When i press the volume button it goes to narrator settings and there's a lady who is speaking(guiding me).
but i don't how to get the volume button back to normal before the Windows 8.1 update.

And i just found out about this volume button problem today as well.

Can someone help me please? Has anyone had this problem?

Thanks.
