digilent atlas spartan6 audio port

hi!

has any one tried to loop back audio from this this kit. i am trying but i didn't achieve any success.

it was written in the reference manual that this is available on their website, but it is not available there.

i asked digilent but they said that we have not completed the design.

Audio loopback should be part of the built-in self test.

 

Digilent have, within the last few hours, uploaded a couple of new designs to the ATLYS page.

 

One is described as follows: "This zip file contains an EDK demo project that illustrates how to use the AC97 codec on the Atlys board with Microblaze."

I have this working in ISE rather than BSB.

 

Full project available.. 

 

http://www.vavi.co.uk/~sleary/SoundDemo.zip

 

It sets up the loopback and then plays out a sine wave on left and right channels.

 

Doesnt use the microblaze setup to do it.. just clocks the commands in frame by frame.
