I would like to ask whether the PYNQ-Z1 can support audio streaming over HDMI i.e., after tying HDMI IN and HDMI OUT, can I stream audio on an external monitor at the output of the HDMI OUT port.

**Configuration**  
Board: PYNQ-Z1  
HDMI IN: Video source (laptop) with audio  
HDMI OUT: Monitor sink (supports audio)

**Setup**

Source code taken from hdmi\_introduction.ipynb notebook.

Thanks for the help!

@techguy

HDMI protocol itself have commercial license fee usage agreement.  
Testing purpose should be good to ignore that.

However this require more complex front and bank porch packages:

Provide a open source design here:  
You can use DMA stream to passive audio to the IP and sampling frequency 48K
