Playing Local Audio Files with .NET MAUI | Community Feed

David Britch’s cross-platform audio control could only pick local files on Windows — until he discovered the file picking issue wasn’t a MAUI bug but a FilePickerFileType misconfiguration. This post explains the fix.

What you’ll learn

Why picking failed — passing file extensions where iOS and Android expect different formats
Platform-specific file types — MIME types (with wildcards like audio/*) on Android, UTType/uniform type identifiers like public.audio on iOS and Mac Catalyst, and extensions on Windows
Supporting older iOS — using system-declared uniform type identifiers instead of iOS 14+ UTType constants
Loading the picked file — small MauiAudioPlayer updates so every platform plays local audio
