hifiberry dac+ zero pi zero and picoreplayer

Hi all,
I've setup a PI ZERO W with hifiberry dac+ zero and picoreplayer.
I doesn't really work well...?
I've tried some Audio output device settings (Hifiberry DAC+ ZERO/MiniAMP, Hifiberry DAC+ Light) with no success ; no error message but no stable sound!
Do you know witch output to use?
And do I need to change the Change Squeezelite settings?
