brief sfw clip with distorted audio typical of all videos

All videos on the aforementioned website play with distorted audio, though the video seems fine. See attached for SFW sample of audio.

Further information:

Other gstreamer apps (totem, sushi) have no problem playing these videos. Nor does Firefox.

Fedora is unable to play videos on this site at all, until the Cisco-provided h264 plugin is installed, and then videos play flawlessly.

Flatpak is also able to play videos without a problem.

Debian plays videos (has h264 support OOTB), but the audio is distorted. This remains true even after installing the Cisco-provided package.

Because Debian native epiphany-browser is the only app that seems to have a problem, might this not actually be a gstreamer bug, but rather something else misconfigured with epiphany or webkit?

System:
CPU: Intel Core i5-8300H × 8
GRAPHICS: Intel UHD Graphics 630 (CFL GT2)
RAM: 16 GB
Model: Dell XPS 15 9570

This is on Debian testing:
Web 46.beta
WebKitGTK 2.42.5
GStreamer 1.22.10

However, this has been true for a long time (possibly forever?), at least a couple of years.

Installed packages include:
gstreamer1.0-vaapi/testing,now 1.22.10-1 amd64 [installed]
i965-va-driver/testing,unstable,now 2.4.1+dfsg1-1 amd64 [installed]

libgstreamer1.0-0/testing,now 1.22.10-1 amd64 [installed,automatic]
libgtk-4-media-gstreamer/testing,now 4.12.5+ds-3 amd64 [installed,automatic]

This occurs with and without gstreamer1.0-vaapi, and regardless of whether I am using intel-media-va-driver (installed by default) or intel-media-va-driver-non-free.
