Hi,

thanks a lot for providing me the tools to stream to my beamer-laptop live using mirracast, unfortunately i wasnt able to get it to work on debian bullseye (11).

i was fortunately able to build it and install it using checkinstall using your guide, ill attach the debian package here, but i cant get it to work as a sink using 

t@tp:~/git/miraclecast/build$ bg
[1]+ sudo miracle-wifid &
t@tp:~/git/miraclecast/build$ sudo miracle-sinkctl

You need to stop existing wpa_supplicant (which is not configured to create wifi direct interfaces). that should be stop network manager or similar.

In wiki there's a faq to provide logs for support. Probably on journalctl it will show that your wpa_supplicant is not correct. Closing this as that is probably the reason. We can reopen if you provide needed logs
