sucessfully compiled lab4 test if you use bin from git you shold hear some sound on headphones, and if you press button you should hear mic input on headphones (passtrue) lab4 is here http://web.mit.edu/6.111/www/f2009/handouts/labs/lab4.html complete project with bin is here https://github.com/goran-mahovlic/ac97_lab4 now it should be easy to do some project from here http://web.mit.edu/6.111/www/f2014/projects/ http://web.mit.edu/6.111/www/f2013/projects/ http://web.mit.edu/6.111/www/f2012/projects/ http://web.mit.edu/6.111/www/f2011/projects/ http://web.mit.edu/6.111/www/f2010/projects/ http://web.mit.edu/6.111/www/f2009/projects/ http://web.mit.edu/6.111/www/f2008/projects/ http://web.mit.edu/6.111/www/f2007/projects/ http://web.mit.edu/6.111/www/f2006/projects/ http://web.mit.edu/6.111/www/f2005/projects/ source is usually in Report pdf so you need to copy paste it to files One note: You need external power supply for expansion board, and it should be at least 7V not 5V as described in manual with 5V you will hear only noise...
so you have build bitstream with code I have send to you, and upload on numato? can you provide some pictures so I can check?
