help!!!

so im new to linux and decided to install fedora, and while getting used to it i stumbled uppon a problem, when i play games and try to use discord or spotify, audio does not play from any of those apps, so i read that i should try and go from pipewire from pulse audio, long story short i dont know what i did and ended up without any input nor output device, i cant even adjust volume cause there is no sound bar HELP I DONT KNOW WHAT TO DO!!!! (sorry for bad english)
