Airplay keeps dropping from itunes on PC to Homepod Mini.

Airplay keeps dropping from itunes from my PC to Homepod Mini.

I have been trying to listen to my apple music on itunes by airplaying to my homepod mini. However, after 3 or 4 minutes or 30 seconds, the connection drops and it comes back by itself after few minutes, and also works if i connect it again. I have this problem since i bought the Homepod mini. I tried every suggestion, restart computer, router, update are always made etc etc Because Homepod mini can not be connected other than with Airplay...i cannot try Bluetooth. I would like to but more Homepod mini but before i do to fix this. Any idea what else could i do ?
