Amplifying NCO signals Zedboard


Dear All,

I have a Zedboard question.
Im trying to generate a sine by using the Zynqbook NCO IP.
Everything seems to be working but the amplitude of the sine is too low.

Im generating a sign with the NCO and I then send it to the Line Out port which is hooked up to an oscilloscope.
Ive already tried increasing the audio mixer and output volume of the Line out ports and mixers but this doesnt seem to change a lot.

Anyone has any idea how  to amplify or generate a sine wave?

Thanks in advance
