Hi, I'm trying to build a headless RPI for music only.
This is a Rpi2 with a Hifiberry Amp+ board. After trying many options, I settled for barebones Raspbian Jessie Lite.
I did the following:
1) modified config.txt to enable the Hifiberry amp
2) created the /etc/asound.conf as per:
3) aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_amp], device 0: HifiBerry AMP HiFi tas5713-hifi-0 
Subdevice #0: subdevice #0
4) tried with sox, mplayer and I get no sound. aplay with a wav file will output only static.. I also run amixer with both controls and set volume to 100%
Any ideas what could be wrong here? This same hardware did work alright with Volumio last night (changed plans because Volumio wouldn't let me handle volume adequately so I want more control)
