Just received my hifiberry DAC+ , tried several hours but was not able to get sound (total silence).
Contents of /etc/modules:
Removed all blacklisted audio related modules in files in /etc/modprobe.d/
Updated raspbian (apt-get update && apt-get upgrade) and run rpi-update

card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ HiFi pcm512x-hifi-0 
Subdevice #0: subdevice #0
Used alsamixer to set playback volume to 100
Now when playing a wav file:
During playback the green led on the DAC+ is flashing but no sound from the analog stereo RCA outputs (total silence).
Is my DAC+ defective of am I forgetting something?
Thanks in advance.
