Fedora 41 - KDE fresh install no sound

All;

I just installed Fedora 41 - KDE on a Lenovo Legion 9, after I did the initial install, and then ran a dnf -y update, I had sound via the laptop speakers. Then I plugged in a monitor and the sound stopped and I have not been able to get it back, even with the monitor unplugged.

Thanks in advance for any help
