I know this question might have been asked several time but no solution yet. I am using HP dm4 1009tu and suddenly the volume bar has gone missing. The quick launch button is working and volume can be increased or decreased but i believe the sound level too has gone down even at the highest peak.
I tried installing the driver but no rescue even restoring at previous time has not helped.
Any solutions for this??? Help is grealty appreciated
