I git clone the source code and followed the instructions to create docker image and run it. However it gives me an error:

[root@mini airplay2-receiver]# docker run -it --rm --device /dev/snd --env AP2IFACE=enp1s0 --net host invano/ap2-receiver

Don't worry about using root account, it is just a test computer. Thank you !
