Bug Description
After updating to Ubuntu 20.04 LTS, the only way of hearing audio is through headphones. 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.
