[HELP] AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO

[rikardo1979]

Hi guys,
Anyone have an experience with this DAC? When I bought this kit from Audiophonics






I thought is ready to use solution where I was shocked it came with no instructions what so ever.
So I thought I give it a try and use it with our XBian which I have been into since we started that project with few guys. But I have realized I ca not make it fully operational as I wanted. The DAC is working fine and can be used as audio out within Kodi but thats not all I want. I would like to make the power button operational and the OLED too. This is where I hit wall in XBian as it is build to different purpose. I have tried a little with one of our developers but it would be a waste of time.

As I am pretty useless with code I cant really do it on my own But I can follow instruction etc and I am familiar with linux as I using it as my main platform, I using Raspberry Pis since they released 1st one having few at home...

So my question is. Is here anyone who has some time and feel to help me to make this working?

edit:I forgot to mention, I using Raspberry 2

edit2: here is short video of the issue I having with this kit. Basically no matter how I try to wire it it does not work as it should. So if I press it once, it does nothing or in other case it powers DAC/RPi but goes OFF instantly. So the RPi LED just flash for few seconds.
Or if I double press it it powers the DAC/RPi but the LED in button keeps flashing!?! But it suppose to stay lit on? It would be pretty annoying to have it flashing on you all the time you have this unit ON!??!

I have realized there is another thread for this DAC. Sorry I have not seen it before I created this. If this is an issue please feel free to merge mods

Hi Rikardo,

That looks like a nice kit. Wish I had seen it b/f I decided to roll my own... (chuckle). Did you get a script or download and install software with the kit to make the button work correctly?

I have looked at that web site in the past, but my French is not good enough to understand all of it. There should be a page where you can download drivers for that DAC, the button, and the display.

I have both Xbian and Rune running on separate Pi2 platforms with HiFiBerry boards, and I used the Mausberry shutdown (although I don't have it connected currently).

That button is probably supposed to activate something like a shutdown command on the Pi, so Xbian or Raspbian etc. can shutdown safely, and then the DAC board does a hard power-down.

Normally you would have a small program running as a service or something similar on the Pi to watch the button, and activate a shutdown. Looks like that may not be installed on Xbian (?)

The ideal person to help you would be Frank.

If he does not get to it first, I will try, because I am doing almost the same with slightly different hardware.

I am certain the kit would work with Xbian also, but it might be necessary to ask on their web site for direction on how to download and use it.

From what I have understood, the directions are to

1) First install a library called "wiringPi".

2) Then, create a script called sds.sh (Raspberry-pwr-management/master/sds.sh)

3) Add the script to rc.local

4) Download scripts for a soft shutdown and soft reboot

5) modify the os to use the Audiophonics scripts

There are also some interesting notes about the power supply in the same thread on Audiophonics, and I do not see what supply you are using. You may want to read those...

If the people who designed the board tell you there is a regulator and you need 6V or more, I would believe them. 5V probably results in sending a low voltage to the Pi, so it may work, but not well.

Which LED is flashing? The one in the button, the red one on the edge of the Pi board?

I do not think that the button can possibly work without some software, like the shutdown script for example.

edit:

If you have a voltmeter, you can check the voltage on the Pi, but I can only conclude that if you use a 5V supply, the voltage at the Pi will be too low to work correctly.
