Title: sound not working in 4.15.0-58, but does in 4.15.0-55 Status in linux package in Ubuntu: Confirmed Bug description: First excuse me, this is my very first bug report, if anything is missing, notify me on email. ---------- I find it rather hard to believe, but since I installed kernel: > 4.15.0-**58** several days ago, my sound on Linux Mint 19.2 Cinnamon stopped working, and no matter what I tried like: sudo apt reinstall alsa-base pulseaudio sudo alsa force-reload + reboot(-s) + alsamixer nothing brought me sound back, so I just installed an older kernel, namely the littlest bit older one: > 4.15.0-**55** now everything works like a charm. ------- How can I debug this and figure out if the problem is a bug in the kernel itself or in some other audio-related package? I don't know what exact information you could require for this. ------- I have just reproduced the problem by upgrading back to 4.15.0-**58** from 4.15.0-**55**. Sound not working again. Plus, by switching to an older kernel proves sound is functional. ------- Hardware: laptop Dell HG6D142: [direct link to product page][1] ---------- $ lsb_release -rd Description: Linux Mint 19.2 Tina Release: 19.2 ----------- expectation: sound working ------- happened: sound does not work at all, neither with Intel GPU, nor Nvidia GPU online, tried all I could mentioned above -------- I attach a simple diff between 55 and 58 loaded. ------- Thank you!
