Hello artvvb, Thank you for the input about the amplifier! I used the following amplifier which I am using for a simpler version of a voice changer using an arduino uno . I simplified the code down to a beeping sin wave and could hear sound from the speakers now. But when I try to add some complexity to my project ie anything over a constant single sin wave there is no sound. Also still trying to troubleshoot the mic but I figure I should get the speakers working first. If anyone has any experience with interfacing the two please input your advice! :)

Hello I have been working on this problem on and off for the last couple months and have not been able to solve it. I am using the pmodi2s2 (https://digilent.com/shop/pmod-i2s2-stereo-audio-input-and-output/) along with the following speaker and mic I have followed this guide on youtube . My problem is the speakers makes no sound and the mic does not seem to work either. I am using the STM32f407 same as the video and have removed the onboard mic the STM32 has as I read that could be a possible problem since it is on the i2s2 line.
