I do also have this problem, as in when I boot up and my external monitor is not connected, I need to mute and unmute the audio so the speakers are working on my laptop.
But even after that, if I connect my external monitor, the laptop speakers will not work and won’t show up in the sound settings, unless I manually change the profile.
I’m not sure the two problems are connected necessarily.
I didn’t have these issues on Fedora 40 though. Neither on kernel 6.11, because I tried it on Fedora 40 before updating to Fedora 41 beta.
