Hi,
Just got my AMP+ today.
The pre-configured image does work.
I run jessie kernel Linux raspberrypi 4.1.17-v7+ and i run a lot of additional stuff on there, not wanting to set that up all over again on a clean image.
Followed all steps in the 3.x.x guide, AMP+ is identified as card 0:0, mplayer does play everything seems to be ok, except there's no sound output.
Volume output is 100% in alsamixer.
Help.
Gr,
Phil.
Please post the output of "amixer" and "aplay -l".
Best regards,
Daniel

This look good so far, but you should NEVER EVER set both volumes to 100%. This might kill your speakers if it is working (you're lucky that it isn't). Before going on with tests I recommend lowering the volumes to 60-70%
Unfortunately I can't see anything that is wrong with your setup. However, there can be a lot of things wrong in a system with a lot of additional software and updates. We have seen cases with filesystem corruptions that couldn't be detected easily and only a fresh installation solved the problems.

Bummer, o well gives me something to do today :)
I started using your install tool, i had a fresh Jessie on my PI2 with working sound.
I did a raspi-config, expanded the FS, enabled the PI camera, reboot.
I did a sudo rpi-update.
I updated sudo apt-get update, sudo apt-get upgrade.
I started adding stuff, installed tightvnc, autocutsel, made it autoboot.
I started adding stuff, installed mplayer, mediaplayer, and everything still worked as expected, sound is good.
I started adding stuff, install hostapd isc-dhcp-server, iptables, wiringpi, and now i'm back to my original situation of the begin post.
So something from the moment i installed hostapd, isc-dhcp-server, iptables and wiringpi made the volume turn to 0.
I think it's wiringpi. Still have to look into it further, luckely i saved my image without these addon's..
It's a bit strange that one of these applications changes the volume control. However, WiringPi can be a problem if you reconfigure the GPIOs that the Amp+ is using.
Best regards,
Daniel
