Voicemeeter | Failed to get OpenAL attributes

When Voicemeeter is running, Minecraft runs at very low FPS (below 0), in both the main menu and in worlds / servers. The log gets filled with:

[Render thread/INFO]: Audio device was lost!
[Render thread/WARN]: Missing sound for event: minecraft:item.goat_horn.play
[Render thread/WARN]: Missing sound for event: minecraft:entity.goat.screaming.horn_break
[Render thread/WARN]: Failed to reset device: Invalid Device

Without Voicemeeter running the game behaves as expected
