Hissing Sound when playing MP3 or Radio

I have just downloaded and flashed the latest Volumio version but after setting it up I only get a hissing sound (like an old TV which wasnt tuned) when trying to play MP3 or Radio streams.

When I play Flac files all is fine?

My setup is RPI 3, Piano Allo 2.1 & Kali



Many thanks, I have set the target bit depth to 32 bit and now I can hear Music :slight_smile:
