LS50W audio stops

Hi everyone,

I’m on the edge of finishing my configuration and I’m running into an issue with my new LS50W. When I try playing to them, they stop playing after 30s and I get an error message in Roon telling me that the connection to the transport was loss.

I attached the log below. My core is running on Windows 10 and everything works great on other devices like my Sonos or receivers through Airplay.

The LS50W works perfectly with their own app.

Thanks,
Steve

This seems to be resolved by disabling Windows Firewall.

A post was split to a new topic: KEF LSX audio stops

I think it’s not wise to disable the firewall totally.

I’m interested, I will also buy those speakers soon.
