UPDATE 11.05.20
I did a fresh install of Ubuntu 20.04.1 today. I did not have to apply the changes noted below. I did not have any sound or video problems. It all just worked. Since the install may not work for everyone out of the box, I will leave the original answer that worked for me below. As always, hope this answer helps someone.
Original Answer Follows:
@Raffa and @Terrance - +1 to you both. Your comments helped to point me in the right direction.
OK, so I have it working now, and here is how I got there. I tried updating grub as suggested in this post:
It borked my video though. Screen would go blank on login, and never return. It lead me to do some additional searching on snd_hda_intel.dmic_detect, and I found the following article:
Way at the bottom of the article it has the following:
sudo gedit /etc/modprobe.d/alsa-base.confAnd then add the following line to it.
options snd-hda-intel dmic_detect=0It's now working 100% for me. All of my hardware recognized and tip-top. I hope this helps someone; thanks all.
I am sorry if I underestimate you, but have you confirmed that your user belongs to the group audio?
groups youruserIf not you can add it with
sudo adduser youruser audioSound card not recognized. My solution. I upgraded from 18.04 within the installed OS to 20.04 and had no sound. "Dummy Output". I tried every solution I could fine with no luck. I finally decided to do a fresh install from a Newly made Live USB. Made sure the speakers were turned on during install just in case it made sound card more visible. After new install everything works. I had no luck try do a reinstall either. Best advice download a fresh ISO and make a Live USB.
