No sound through built-in speakers (dv7-1243cl)

There is no sound through the built in speakers. The mute button on the touchbar under the screen is lit up red but the icon on the screen shows that it is unmuted. Whenever I try to disengage the mute on the bar, the light stays red but the volume icon changes. I'm pretty sure that its muted through the touchbar, is there specific software to re-install the touchbar?
