[MS-7C52, ATI R6xx HDMI, Digital Out, HDMI] No sound at all, second display not working, cpu/agpu performance dropped considerably

[Hassan Williamson]

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:

```
libnss-systemd:amd64=245.4-4ubuntu3.3 libudev1:i386=245.4-4ubuntu3.3 libudev1:amd64=245.4-4ubuntu3.3 libudev-dev:amd64=245.4-4ubuntu3.3 udev=245.4-4ubuntu3.3 systemd-timesyncd=245.4-4ubuntu3.3 systemd-sysv=245.4-4ubuntu3.3 libpam-systemd:amd64=245.4-4ubuntu3.3 systemd=245.4-4ubuntu3.3 libsystemd0:amd64=245.4-4ubuntu3.3 libsystemd0:i386=245.4-4ubuntu3.3 libapt-pkg6.0:amd64=2.0.2ubuntu0.2 apt=2.0.2ubuntu0.2 apt-utils=2.0.2ubuntu0.2 ubuntu-release-upgrader-gtk=1:20.04.29 ubuntu-release-upgrader-core=1:20.04.29 update-manager=1:20.04.10.1 update-manager-core=1:20.04.10.1 python3-distupgrade=1:20.04.29 python3-update-manager=1:20.04.10.1 update-notifier=3.192.30.3 update-notifier-common=3.192.30.3 libnetplan0:amd64=0.100-0ubuntu4~20.04.3 netplan.io=0.100-0ubuntu4~20.04.3 mutter-common=3.36.6-1ubuntu0.20.04.2 gir1.2-mutter-6:amd64=3.36.6-1ubuntu0.20.04.2 libmutter-6-0:amd64=3.36.6-1ubuntu0.20.04.2 jq=1.6-1 libjq1:amd64=1.6-1 linux-firmware=1.187.7 linux-generic-hwe-20.04=5.8.0.38.43~20.04.23 linux-image-generic-hwe-20.04=5.8.0.38.43~20.04.23 linux-headers-generic-hwe-20.04=5.8.0.38.43~20.04.23 linux-headers-generic=5.4.0.62.65 linux-libc-dev:amd64=5.4.0-62.70 mutter=3.36.6-1ubuntu0.20.04.2
```

This list was generated with the command:

`awk 'BEGIN{ start="0" } { if($0 ~ /Log started: 2021-01-20/) { 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.

Forgot to mention in the original post, but trying to revert all updates that caused the problem (as per the versions listed above) but that didn't work because they no longer exist in the repo (and the system had already cleared the cache). So I always get the error that the package(s) were not found:

I've done more digging and I think the regressing happened sooner, but I only rebooted it on the day I noticed it wasn't working. I decided to see when the system was actually last rebooted by using:

$ last reboot | less

reboot system boot 5.8.0-40-generic Fri Jan 22 11:44 still running
reboot system boot 5.8.0-40-generic Fri Jan 22 10:15 - 11:44 (01:28)

reboot system boot 5.4.0-58-generic Mon Jan 4 10:00 - 03:42 (5+17:42)

You'll see everything was fine on the 10 Jan 2021 and 4 Jan 2021. That means the regression happened on or after these dates. I've rerun the awk command to see what packages were changed in that time and I have:

$ awk 'BEGIN{ start="0" } { if($0 ~ /Log started: 2021-01-05/) { start="1"} if ( start == "1" && $0 ~ /Unpacking.*over/) {gsub(/[\s\t)( ]+/,"",$5); printf("%s=%s ", $2 , $5)}}' /var/log/apt/term.log

Hi @kaihengfeng thank you very much for commenting, much appreciated.

Yes, linux-modules-extra is installed:

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1912773

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Fixed it! However I'm not sure why the file was created when I'm running on AMD hardware and requiring the use of the APU.

The bug is that a blacklist file was created in:

/etc/modprobe.d/blacklist-amdgpu.conf

With the following line:

blacklist amdgpu

That obviously prevented the APU drivers to load up, so the HDMI audio sink could be initialised and prevented GPU rendering.

This problem could likely affect multiple people and are unaware if they are on a single display and using speakers connected to the motherboard instead of via other means such as the 3.5mm output, optical, or even via Bluetooth. Since the system worked otherwise. The only symptom people on single displays and not using HDMI audio people would experience is when doing anything CPU or GPU intensive, since I can only presume the CPU is doing all the legwork to render the display instead of the APU.

For reference the CPU is a AMD Ryzen 5 3400g with Vega 11 APU, and no dedicated graphics card.

If anyone needs any additional information, logs, or anything let me know and I'll be happy to help out where I can. I'm just glad that I got this resolved, but I'd hate for others to experience the same issues while updates trickle down (it could also be months before anyone notices on single display and no HDMI audio setups).

[Hassan Williamson (hazrpg)]

This issue still exists, when trying to figure out why bug #1962308 was happening, this exact same problem still happens on 5.8.0-63 (originally reported on 5.8.0-40).
