Dear All,

I'm afraid I need your help. I have followed config guides closely, have redone all on a second Raspberry + AMP system to be sure HW is fine, and still AMP wouldn't play me a song.
My suspicion is that also the AMP is now affected by Linux 3.18.x changes regarding device tree files etc.

Here's my story:
Updated kernel, synced and rebooted. uname -a brings "Linux myplayer 3.18.3+ #739 ..."

Started configuring with guide, and, as advised for AMP, went back to /etc/modules. Followed the list, and only had to create /etc/asound.conf for ALSA, since the rest (blacklist and modules) looked okay.

Rebooted, and aply -l still brings "aplay: device_list:268: no soundcards found..."

End of my story, end of my capabilities. Kindly ask for some advice.

Cheers, Georg

  Started with "Configuring Linux 3.18.x", and as advised for AMP, went back to guide "HiFiBerry software configuration (Linux 3.12)"

  It seems that the Raspbian kernel is not working without the device tree overlay for the Amp, which is missing. We have to work on this and create a patch. This might take some time. We will look into this next week.
