Graphics Card Firmware
Update the video firmware of an AMD Radeon RX 9000 card on Linux, so SDR streams go back to full range.
Update the firmware your AMD graphics card loads, so the Graphics card firmware health check turns green and SDR streams go back to full range.
The check warns on a Radeon RX 9000 card whose video firmware is older than 9.13.38. That firmware converts SDR correctly at limited range only, so Punktfunk streams SDR at limited range on the card. The picture is right and HDR is untouched.
The fixed firmware is not in a linux-firmware release yet. Until it is, an update changes
nothing here and the check keeps warning.
Check the version
Health checks on the web console's Troubleshooting page shows the version in the Graphics card firmware row. In a terminal:
sudo dmesg | grep "VCN firmware"ENC: 1.13 DEC: 9 … Revision: 33 is firmware 9.13.33: the DEC number, the second ENC number,
then Revision.
Update
The firmware ships with your system, in its firmware package. Update the system, then restart the computer: the card loads its firmware at boot.
| System | Update |
|---|---|
| Arch, CachyOS | sudo pacman -Syu |
| Ubuntu | sudo apt update && sudo apt full-upgrade |
| Fedora | sudo dnf upgrade --refresh |
| Bazzite, Fedora Atomic | ujust update, or rpm-ostree upgrade |
| SteamOS | Settings → System → Check For Updates |
| NixOS | nix flake update nixpkgs in your flake directory, then rebuild |
After the restart the check reads the new version. From 9.13.38 on it turns green and the next SDR stream is full range again.
