Not working, no solution found yet

Hi,
I tried to get my HifiBerry running today:

OS: Raspian

LED works

First had the wrong tutorial so was using _dac instead of _digi in etc/modules

uname -a tells my Kernel is 3.12.28+

blacklist spi-bcm2708
# blacklist i2c-bcm2708

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HifiBerry Digi HiFi wm8804-spdif-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0


aplay file.wav causes
aplay: set_params:1087: Channels count non available

aplay -D plughw:0,0 file.wav causes
aplay: set_params:1145: Unable to install hw params:

when using mpg321 with my own Beep:
Can't find a suitable libao driver. (Is device in use?)

In alsamixer I see AIF and TX, both down, and there is no entry for Chip. At F2 > PCM I see wm8804-spdif-0, but can't remember to have a driver loaded for that.

amixer -c 0
Simple mixer control 'AIF',0
Capabilities: pswitch pswitch-joined penum
Playback channels: Mono
Mono: Playback [on]
Simple mixer control 'Input Source',0
Capabilities: cenum
Items: 'S/PDIF RX' 'AIF'
Item0: 'AIF'
Simple mixer control 'TX',0

Have to add:
- I'm not soldering much, maybe this caused the problem. Have been carefull.
- My power supply is only 700mA, but there is nothing else running.
