Driver doesn't support sample playback

Hello everyone! I recently tried the new “Sample” feature of Godot out, and while my short SFX all work, it seems that my background music just refuses to play with the following error:
W 0:00:01:0011 start_sample_playback: Trying to play stream (-9223371993435339326) as a sample (-9223371995196947064), but the driver doesn't support sample playback.

Honestly, I have no idea what I have done wrong. The stream is just a simple MP3:

Could it be that maybe the file is just too big (288 seconds)? But I haven’t found anything about a length restriction in the docs nor in the blog post discussing the audio changes.

I am on v4.3.stable.official [77dcf97d8].
My system info in case that’s needed: Godot v4.3.stable - Windows 10.0.22631 - GLES3 (Compatibility) - NVIDIA GeForce RTX 4070 Ti SUPER (NVIDIA; 32.0.15.6094) - AMD Ryzen 9 7900X3D 12-Core Processor (24 Threads)
