Fedora 31 sound issues (Dell Inspiron 5491)

Hello! A while ago I installed Fedora 31 (KDE Spin) on my laptop (Inspiron 5491) and I’m unable to get sound from my internal laptop speakers or through the audio jack. I am able to get sound output through Bluetooth, but it’s incredibly quiet even when volume is increased to 150%. I have tried the steps shown here.
