You have been subscribed to a public bug:
After a recent update, I now have a system that can no longer play audio
(via HDMI), my second monitor (DVI) is no longer being picked up, and
CPU/AGPU usage has lost a lot of performance (OBS is basically unusable
at this point).
Whatever has happened with the recent updates has caused the AMD drivers
(presumably?) to not work correctly - because it is an AMD Ryzen 5 3400g
(with no dedicated graphics card).
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
-> About Ubuntu
```
$ lsb_release -rd
Description: Ubuntu 20.04.1 LTS
Release: 20.04
```
2) The version of the package you are using, via 'apt-cache policy
pkgname' or by checking in Software Center
Not sure which package would be the cause, however these were the
version that were working prior to the update:
```

start="1"} if ( start == "1" && $0 ~ /Unpacking.*over/) {gsub(/[\s\t)(
]+/,"",$5); printf("%s=%s ", $2 , $5)}}' /var/log/apt/term.log`
3) What you expected to happen
Sound and video working via HDMI on primary monitor, second monitor
displaying (extended) video via DVI. CPU and AGPU being able to render
via OBS.
4) What happened instead
No sound. No second display. Any CPU or AGPU tasks running slower than
normal.
