Fedora 36 Kinoite shows speakers (unavailable) even though speakers work during test

I recently installed Fedora Kinoite on my ThinkPad E590, and noticed that no sound comes out of the speakers. If I go into System Settings > Hardware > Audio, the Playback Devices port defaults to Headphones, and if I click the drop-down menu, it shows Speakers (unavailable) like in the picture below. If I then perform a test, the speakers do output sound.

Any idea how I could go about finding what the problem is?
