My tablet has faint audio when in phone mode. Is there any way I can fix this?

How do I adjust volume up. It works OK with headphones.

Which tablet?
You made sure the volume sliders are all the way up in sounds ?

Welcome to Android Central! What do you mean by "phone mode"? Are you actually making phone calls on it?
