I’ve been running Ubuntu 16.04 LTS since it was released (and the 2 LTS releases prior) and was quite happy with it. Then, an ALSA update caused the soundcard to dissapear. Searching around a bit online I discovered that this is a very well nown issue with Ubuntu going back to version 12 at least.
I performed a clean install of 18.04, restored my data and all is well once again. I like the new look of Bionic Beaver but the sound card issue is troubling.
