How to debug B+/DAC+ ?

I have followed install instruction for DAC+ on RPI B+.

I *did* have success a few days ago; after a break I now get no sound from RCA outputs.

I followed install instructions:
* rpi-update
* remove blacklist files
* cat /etc/modules:
snd_soc_bcm2708
bcm2708_dmaengine
snd_soc_hifiberry_dacplus

* result of aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ HiFi pcm512x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

* cat /etc/asound
pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}

I tried the test image -> no sound produced

When I boot, the DAC+ light comes on

Any suggestions on what to check?

Is it possibly an alsa config problem?

* amixer info
Card default 'sndrpihifiberry'/'snd_rpi_hifiberry_dacplus'
Mixer name : ''
Components : ''
Controls : 15
Simple ctrls : 14

Regards

Richard
