[How to do instruction] AUDIOPHONICS RaspDAC Mini Kit - I-Sabre ES9038Q2M

[rikardo1979]

---

Couple of days ago I have ordered and received this latest kit from Audiophonics 

I is the new  AUDIOPHONICS RaspDAC Mini Kit - I-Saber ES9038Q2M








It supports payback up to 32bit 384kHz / DSD 128


Now I have this new DAC fully working with latest moOde thanks to a guys from Audiophonic @audiophonics  directly who provided an extended support and help me a lot
So I take no credits for any of this what so ever!

Here is how to enable DAC
(obsolete on moOde 5.x versions as driver is included in kernel)

Driver installation

Code:

sudo apt-get install minizip
cd /home/pi

wget https://github.com/audiophonics/Volumio2_I-sabre9028_plugin/raw/master/Q2M_kernel_4.14.71.zip
miniunzip Q2M_kernel_4.14.71.zip

cd Q2M

sudo cp i-sabre-codec.ko /lib/modules/4.14.72-v7+/kernel/sound/soc/codecs/
sudo cp i-sabre-k2m.ko /lib/modules/4.14.72-v7+/kernel/sound/soc/bcm/
sudo depmod -a
sudo cp i-sabre-k2m.dtbo /boot/overlays/

Now in Settings>Audio config select I2S audio device=Audiophonics ES9028 DAC and reboot system

To enable driver we need to add dtoverlay=i-sabre-k2m into /boot/config.txt

Code:

sudo nano /boot/config.txt

so it will look like this 

Code:

dtparam=i2s=on
dtparam=audio=off

dtoverlay=i-sabre-k2m
dtparam=spi=on
#dtoverlay=rpi-dac
#dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt

Make sure you have the rpi-dac commented out #

Now we can reboot system after which new driver should be in place. We can check by 

aplay -l 

Code:

pi@moode:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: DAC [I-Sabre K2M DAC], device 0: I-Sabre K2M DAC i-sabre-codec-dai-0 []
 Subdevices: 0/1
 Subdevice #0: subdevice #0

So with this you should be able to use Hardware volume control under 
Settings -> MPD -> Volume 


Making OLED working (SPI port)

Code:

sudo apt update
sudo apt-get -y install python-dev python-pip libfreetype6-dev libjpeg-dev python-smbus
sudo pip install -U pip
sudo -i pip install --upgrade pip setuptools
sudo -H pip install --upgrade luma.oled

add "spi-dev" to /etc/modules 

Code:

sudo nano /etc/modules

Code:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

spi-dev

CTRL+X > Y to save change 


add "dtparam=spi=on" to /boot/config.txt

Code:

sudo nano /boot/config.txt

Code:

disable_splash=1
hdmi_drive=2
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=off

dtoverlay=i-sabre-k2m
dtparam=spi=on
#dtoverlay=rpi-dac
#dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt

Download attached file oled.zip. Unzip and extract 'oled' folder into /home/pi/

Now go into the directory

Code:

cd /home/pi/oled 
sudo chmod 755 /home/pi/oled/moode_oled_1.54_spi_audiophonics.py
sudo cp oled.service /etc/systemd/system/
sudo systemctl enable oled

Now all should be set and we can reboot after which we should have OLED display working


Remote control & SPDIF input 

First we need to install lirc 

Code:

sudo apt-get -y install lirc

Download lirc.zip file. Extract all the files and place them into /etc/lirc (replace the existing files)

Edit

Code:

sudo nano /etc/modules

and add 

Code:

lirc_dev
lirc_rpi gpio_in_pin=4

CTRL+X > Y to save change

Edit 

Code:

sudo nano /boot/config.txt

and add 
(for moOde versions 4.x)

Code:

dtoverlay=lirc-rpi,gpio_in_pin=4

(for moOde versions 5.x)

Code:

dtoverlay=gpio-ir,gpio_pin=4

CTRL+X > Y to save change

Edit

Code:

sudo nano /etc/rc.local

and add

Code:

/usr/bin/irexec -d /etc/lirc/lircrc

CTRL+X > Y to save change

Download spdif.sh and place it into /home/pi

Check your card number and make a note of it. In my case it was card 0

Code:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: DAC [I-Sabre K2M DAC], device 0: I-Sabre K2M DAC i-sabre-codec-dai-0 []
 Subdevices: 1/1
 Subdevice #0: subdevice #0
 

Edit your spdif.sh accordingly on all lines ( -c 0 )

Code:

#!/bin/bash
# Audiophonics
if [[ `amixer sget -c 0 'I2S/SPDIF Select' | grep Item0: | awk '{print $2}' ` =$

then amixer sset -c 0 'I2S/SPDIF Select' SPDIF

else amixer sset -c 0 'I2S/SPDIF Select' I2S

fi

Now we can reboot system after which your remote control should works and you should be able to use digital (SPDIF) input.
Remote control can operate 

• Play/Pause
  
• Next/Previous track from playlist (Left/Right) 
  
• Vol Up/Down (Up/Down)
  
• Stop (OK/Mid button)
  
• SPDIF/Card (Menu button)

Hi Ricardo. This will only work with SPI and sabre9028?

Hi Ricardo. This will only work with SPI and sabre9028?

This is written to works with SPI type display ans Sabre9038Q2M DAC which is part of this kit

[kit1cat]

Like the idea of the digital input, does the software fully support it?

[rikardo1979]

Yes it can work. I have tested but I have no use for it.
There is another script to activate it but its not a part of this instruction.
Once you run the script only digital in through DAC works. Display is OFF that time

Hi rikardo - thanks for posting the guide - very useful!
Just to be clear - with the driver installed, we can control the dac ess internal hardware volume using the moode web interface remotely?
Thanks Adrian

Yes thats right

The kit looks better than ever now that you've posted this guide. +1

Just so people don't panic, that first wget instruction is only one line which ends "_4.14.71.zip" (the first browser I used split the line after "I-") *and* it only downloads drivers, not the full 4.14.71 kernel.

Tim's upcoming r4.4 release includes a bump to kernel 4.14.79 so there'll likely be some adjustments needed to make this setup work with it. With luck the drivers will continue to work and you just need to copy them to whatever modules directory the new kernel uses. Presumably something like "/lib/modules/4.14.79...".

Kent

The SPDIF script is activated with remote "Menu" button. (amixer command)

And you keep volume display when switching to SPDIF input

Nice one ?? Haven't tested this yet. So will give it a go
