Background - I was originally trying to resolve the issue of Question - No audio in laptop speakers or headphones, but sound plays in screen (HDMI connection), I suspected kernel update and with the help from comments in Question - In the package logs, what are the kernel updates listed as?, I was able to discern kernel version I wanted to try booting into to see if the issue is resolved.
Right now, I have managed to install the kernels for specific version by installing appropriate linux-image
(s) and the linux-header
(s) only, but when I do boot using these kernels from the GRUB menu, the OS can not find my WiFi Adaptor, and for the sound it shows "Dummy Output". I installed 3 kernels on top of the existing one, and this issue is happening with them all.
Am I missing a crucial step or detail here?
