Volumio output via HiFace1 (RPi)

Hi guys,
I am trying to set up my Raspberry Pi Volumio System to work with Hiface 1. Did anybody of you succeed in doing so yet? Yesterday I tried to get it running using the “protocol” which was published for Raspify (raspyfi.com/hiface-on-linux- … nd-debian/) but I failed:

After the command: apt-get install kernel-headers-$(uname -r)
I got the error message: E: Unable to locate package kernel-headers-3.10.30
E: Couldn’t find any package by regex ‘kernel-headers-3.10.30’

Is anybody of you able to guide a Linux greenhorn like me through the process?

Thanks in advance and kind regards,
