Probably a look at alsamixer to make sure the level is turned up and not 
muted will help. Internal audio on most computers is quite confusing 
sometimes. When pulse is controlling the device it hides all the stuff it 
is doing. Jack on the other hand just feeds audio to the device. There 
will be (at least) three level controls you wish to look at:
  - Master
  - headphones
  - speakers

The last one may be labeled Front instead as mine is. I alsa control each 
stereo pair has a mix strip. The colour strip shows level, the box at the 
bottom will have "MM" if Muted or "00" otherwise. use your arrow keys to 
move the red highlite to the channel you wish to adjust. Up and down 
arrows will change level, M will mute/unmute.

Alsamixer is a terminal application by the way. QASMixer will work if you 
wish a GUI version, but really, alsamixer is a part of alsa and so should 
just be installed if alsa is there. Also with QASmixer, make sure it is 
pointing at the audio device and not Pulse (where it defaults to). 
Alsamixer never points at pulse :)
