Help with audio codec

Greetings

I got this code on verilog hdl

high speed pusuit

which you can find in 'fpga4fun dot com' / musicbox2 dot html

and it works perfectly, the thing is I want to make a circuit which includes many cases like this, but with different sounds every time, and I just don't know how to do it. For example, with one push button switch I select a police siren sound, I push the second and there's a ambulance siren...

Help me please, I am a begginer.

I'm using QUARTUS II 7.2 and cyclone II

I'm using the expansion headers to connect it to the speaker but I want to use the lineout of the audio connectors and I don't know how or the correct audio pins for it.

Please help me.

    Hi, when you said it works, do you mean yo can hear it from a speaker or something, or just the simulation works.

    Also if you have managed to get it working and can listen from speaker, could you please help me out. Thanks.

    You probably will need some RAM storage to place your PCM sound and send it eventually to the CODEC.
