[Bug 41285] Re: Some audio files have wrong icons

[Sebastian Dröge]

Thanks... so it doesn't get the correct mimetypes for some reason.

Could you please call
grep -R "x-extension" ~/.local/share/mime
and paste the output here?
I have the bad feeling that you already assigned a mimetype to files with those extensions for your user which then overrides the system settings.
