Hi people, I am planning to use the Audio Codec in the DE2 Altera board. I have already found the demo project DE2_Audio_Example file from Altera site but it is in verilog. I am desperately looking for the VHDL version of it if there is one. And out of curiosity why are all Altera demos in Veril...
vhdl - Filtering sound on a DE2 FPGA - Stack Overflow
https://stackoverflow.com/questions/29103927/filtering-sound-on-a-de2-fpga
HI I am building a filter in VHDL, when I program it in the DE2 board the sound goes throught input port of the FPGA and out to the speakers not problem but when I move a switch to high to activate the filter no sound comes out. I have no clue what is the problem. I will attach the code with the hope of that you can help me to find the bug.

Hello, I am attaching a VHDL file which describes an interface to the Wolfson WM8731 Audio Codec chip located on the Altera DE1 and DE2 boards. This version just does output, but you can augment it to do input. For this you will have to read over the WM8731 datasheet. I have tested this on both the DE1 and DE2 boards.

Program the Altera’s DE2 FPGA board Discussion VHDL is a high-level, modular language first defined by the IEEE Std 1076-1987. This standard has been revised by IEEE Std 1076-1993 and again by IEEE Std 1076.3-1997. The V in the acronym VHDL represents Very High Speed Integrated Circuit (VHSIC) and HDL stands for Hardware Descriptive Language.
