Public bug reported: Recently I bought a new Inspiron 3501, and it came pre-installed with Windows 10. I wanted to try Ubuntu linux on it so, I dual-booted Ubuntu 20.04 on it to check if everything is working fine. After installation, everything is working fine except the audio output. The sound kind of crackles. It works perfectly fine on windows though. I tested inbuilt speakers, Bluetooth headset, and output from 3.5 mm audio jack but no difference. I tried youtube videos and local audio and video files but the outcome is the same. I tried many online solutions but without any success. I also installed Ubuntu 21.04, to check if the new kernel brings any improvement but the condition was the same. Don't know how to fix this issue. Any help is appreciated.
