>>76347549Ubuntu. Still doesn't work. Sound file plays normally when I manually copy the sound file link to a new tab. Video and images play/show as normal when opened in a new tab. It's specifically the combination of the two in a soundpost that doesn't work. Using 4chan sounds player script if that makes any difference.
That said, it might be fine for others. My systems a bit fucked having dragged it through 10 years of system upgrades and migrating from Xorg to Wayland, changing DEs, etc.
