piCorePlayer 3.10 and HiFiBerry DAC+ no output

Hi,

Running PCP 3.10 and a HiFiBerry Dac + HW version 2.06 I am getting no sound using Audio Output HIFIBerry DAC+ and output setting sysdefault:CARD=sndrpihifiberry.

Can any one offer a suggestion as to what I am missing or doing wrong.

Thanks in advance,

Howard
