			Hi
If somebody else is looking for solution.
This is the way i do it working with 0.3-alpha iqaudio dac+ and M2tech 
upgrade kernel 
pacman -S linux-raspberrypi
pacman -S linux-raspberrypi-headers
verify /boot/config.txt 
kernel=kernel.img
cmdline=cmdline_rune.txt
edit /etc/modules-load.d/raspberrypi.conf
snd_soc_pcm512x
snd_soc_iqaudio_dac
reboot
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: M20 [M2Tech USB Audio 2.0], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: sndrpiiqaudioda [snd_rpi_iqaudio_dac], device 0: IQaudIO DAC HiFi pcm512x-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0
activate iquadio  with RuneUi  => Settings => Is2 modules
Now i can start to compare this 2 dac, and test 0.3-beta
Regards
