Is et possible to make a guide to set up a Raspberry 2 to Hifiberry Amp+
A have a Pi 2 out of box, your setup configuring for Linux 3.18.x is incomprehensible.
I have installed the NOOBS from www.raspberrypi.org/downloads.
But from the installations there is there no:
1: /etc/modprobe.d/raspi-blacklist.conf
2: /etc/modules.
3: /boot/Config.txt
I don’t want to use OpenElec only make a project with sound.
Please a make list, point for point what to do.
it should preferably be a success to use HifiBerry.

HiFiBerry team Hi Steen,
NOOBs seems to have some files in different locations. I recommend using Raspbian directly, not via NOOBs. The configuration guide should work for this. Alternatively you can just download our Raspbian image with auto-detection from here:

HiFiBerry team Hi Steen,
jackd doesn't work with addon sound cards as it needs a feature that is not supported (memory-mapped IO). I don't know about SonicPi. The SonicPi developer got a test board from us, but I haven't heard yet, if he found a solution. You might ask him directly. Maybe he can tell more.
Best regards

rbn I think you may be able to get Sonic Pi working with the sound cards now if you update do kernel 4.1.x
This can be done with rpi-update. It will also include some further dtoverlay files. The reason Sonic Pi doesn't work with the HiFiBerry DAC is that it uses jacks to connect and this requires a memory mapped IO connection which isn't supported on the current release kernel.
With the new kernel installed you should be able to add TWO overlays to the config.txt file in the boot partition.
The first will be dtoverlay=hifiberry-dacplus and the second dtoverlay=i2s-mmap
This new overlay sets up the kernel to allow jacks to work with map io
I haven't tried this myself, as I have an IQaudio DAC board, but this suffered from the same problem, and uses the same solution with the alternative overlay IQaudio-dacplus instead of the hifiberry one.
I assume the berry board will set itself up in the default card 0 position, and if so, sonic-pi should then work without modification.
Hope this helps
