Hi all.
At last, I have finished my Volumio Music player.
I was looking for a way to build a player which would hold my complete digitized music collection and simply send it out of the other end directly to a pair of speakers, with of course some means of seeing what is going on and a method of controlling it.
I had never even looked at anything to do with Raspberry Pi before and so Googled to find something that would suit my needs.
I soon ended up with a plan to use a Pi and IQAudio Digi-amp+ with Volumio as the operating system.
I built my box after obtaining all of the hardware which had to go in it and working out some dimensions
Main components -
Pi (latest)
IQAudio Digi-Amp+
500gb Usb hdd with 12 volt power supply
19volt power supply for Pi and Digi-Amp
An Android phone
The front panel is fitted with an illuminated push button for soft shutdown/restart.
On the back panel is the power cord, a lan cable. a 240volt rocker switch for complete shutdown., an sd card socket, speaker terminals, and a usb plug/socket to allow me to get access to the hard drive for adding to or modifying my music collection.

I used the following GPIO pins for wake up, send to sleep, and the led.
Wake up - GPIO 3 & GROUND
Sleep - GPIO 26 & 3V3
Status LED - GPIO14 (TXD) & GROUND
Wake up worked as it was
Sleep uses the buttons plugin in Volumio with shutdown set to 26
To get things to work correctly I had to add the following -
enable_uart=1
dtoverlay=pi3-disable-bt
At this stage I had already fitted a single pole push button with led into my front panel and glued it in place. To get both wake and sleep to work with this button I wired in a couple of 12 voltmicro-relay modules and slaved the 12 volts from my hard drive power supply. It all works perfectly.
I messed around with resistor values for the led so that minimal current was drawn without making the led too dim.
I must say at this point, that without the help from many of you on this forum I would have been lost on several aspects of the project.
TO BE CONTINUED
I installed Volumio 2 without any problems and it worked straight away.
I am using hotspot only and my android device finds it every time that I run the program.
I have managed to take a Oneplus A3003 phone out of service and it has now got no sim card in it. I removed as many other apps as possible and shut down most other installed services. As a result the phone is now just a remote access to my player.

I would once again like to thank everyone who has helped me via the forum to get this project up and running.
