I was trying to enable noise cancellation on ubuntu 20.04 LTS and was able to do it from here. Then I was trying to fix echo from local speakers and followed this tutorial and I was no longer able to get sound from the microphone, anyone can please help me and also enable noise cancellation and also fix echo from local speakers ? thanks in advanced !!

A 10 years old tutorial is hardly relevant due to the huge changes any OS experiences in such long period of time. That said the second guide you followed simply calls for changing the audio card output. It should be easily reversible. – ChanganAuto Nov 23 '21 at 12:04
