Cannot get hardware acceleration to work with .rpm and Arc A310

[kabsdk 0]

I’m currently running Emby on an AlmaLinux 9 VM in Proxmox, installed using the CentOS RPM.

Problem:

Hardware acceleration/transcoding is not actually being used.
During transcodes, CPU usage hits 100% across all cores, there is no GPU utilization, and there is no “hardware” icon beside the transcoding stream (as shown in my screenshots).

Emby does recognize the GPU, at least I'd think so with Emby displaying the GPU name under "Transcoding" in the settings menu. A Plex instance on the same physical server performs proper hardware acceleration (Plex is deployed bare metal, like Emby), so the GPU drivers should be installed and working correctly.

Emby settings are configured as follows:
Preferred Hardware Decoders are all set to VAAPI, and Preferred Hardware Encoders are set to QuickSync (the only available option).
Software tone mapping is disabled.
Hardware Accelerated Tone Mapping is enabled.
Intel QuickSync tone mapping is disabled, and VAAPI tone mapping is set to VAAPI HW Tone Mapping.

Hardware and versions:

Emby version is 4.9.3.0, also tried with the latest "official" RPM, version 4.9.1.90-1

GPU is a SPARKLE Intel Arc A310 ECO.

Permissions and setup:

User/group and device permissions look like this:

[kabs@plex01 ~]$ id emby
uid=985(emby) gid=986(emby) groups=986(emby),39(video),998(render)

[kabs@plex01 ~]$ ls -la /dev/dri

Systemd service configuration:

[kabs@plex01 ~]$ systemctl cat emby-server

/usr/lib/systemd/system/emby-server.service

The GPU is passed through to the VM.

Logs have been attached. Any help is appreciated.
