Activate i2s driver for HifiBerry - no soundcard [FIXED]

Hello!
Have a Hifiberry Soundcard. Has activated in backend from Volumio the driver and has restarted. The Hifiberry is not found.

/etc/modules looks this:
snd_soc_bcm2708
snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_pcm5102a
snd_soc_rpi_pcm5102a

root@volumio: / etc. # aplay -l
aplay: device_list:252: no soundcards found…

Please, around help.
