I asked a very bad question related to this yesterday, sorry - this is more comprehensive and makes more sense.
this is the manual for the nexys 4 FPGA i'm using https://reference.digilentinc.com/reference/programmable-logic/nexys-4-ddr/reference-manual - the relevant section is 16 - mono audio output
based on this manual, I have set the audio output to a pulse-width modulated square wave in order to try to produce a tone (the idea is that I will eventually play a short tune in the background of an arcade game I'm building for a university project). Although there are no errors or anything, I'm not hearing anything when I plug headphones into the audio output.
I'm wondering if I'm going about this the right way and whether anyone has any tips on how to produce a sound output - any sound, really, and I can build from there.
I really appreciate any help
