The sound settings tab doesn't even show any other output option other than "Dummy output" . I have already checked other versions and everything works perfectly when I downgrade to Ubuntu 19.10, so I think this is a version related bug. Just to reiterate my laptop is a DELL Inspiron 14 3420.The sound card showing in alsamixer window is HDA Intel PCH, and the chip is Cirrus Logic CS4213. I have looked up solutions online for 2 days and none has worked.
