    USB audio on PYNQ-Z1

    Thank you so much for your reply! Im using 4.19.0-xilinx-v2019.1. I downloaded the image for the pynq z1 v2.5 from http://www.pynq.io/board.html. I am currently using the Ugreen audio adapter seen on amazon here: https://www.amazon.ca/UGREEN-Universal-Headphone-Microphone-Raspberry/dp/B01N905VOY. I am trying to feed the pynq z1 board audio from my phone via a 3.5mm extention cord connected to my phone at one end and the ugreen adapter at the other. This is in turn to the z1 via usb.

    USB audio on PYNQ-Z1

    Hi there, I am pretty new to using the pynq-z1 board. I wish to do some audio recording via a usb microphone! I am struggling with doing this successfully, is anyone able to help me with this? I am getting "no soundcards found" when issuing alsa commands arecord -l and aplay -l. I understand pynq -z1 receives audio samples as PWM or PDM, but im not sure exactly what that means in terms of linux drivers available. any help would be appreciated! Thanks
