Got the following in Putty.

/usr/local/lib/python2.7/dist-packages/luma/core/interface/serial.py:185: RuntimeWarning: This channel is already in use, continuing anyway.  Use GPIO.setwarnings(False) to disable warnings.
  self._gpio.setup(pin, self._gpio.OUT)
Exception - Main Module
(<type 'exceptions.SystemError'>, 'raspdac_oled_main.py', 175)

Had already commented line 281, just edited it again using notepad in Windows but still getting the same error.

Code:
try:
              self._spi = spi or self.__spidev__()
              self._spi.open(port, device)
#              self._spi.cshigh = cs_high
             except (IOError, OSError) as e:
              if e.errno == errno.ENOENT:
               raise luma.core.error.DeviceNotFoundError('SPI device not found')
           else:  # pragma: no cover
               raise

Just completed an in place update from moOde 6.5.2 to release 6.6.0 and both the display and remote are working.

Success  Smile

Turns out my problem was the editing of the  serial.py file using a Windows text editor, used sudo nano from Putty and it's now up and running.

Thanks again, TookaFace.

Early boards have this problem with RPI4.
It has been fixed for boards sold after September 2019
Sent my DAC to back to the Audiophonics headquarters for a software update and am very pleased to confirm that the kit is fully working with the Pi 4. Mille merci!

Do you get access to all the filters?

Updated procedure for moOde 6.6 ==> moOde 7.4.0:
I've added a system menu in oled display, where you can reboot/shutdown the raspdacmini.

Code:
sudo apt update
sudo apt-get -y install python-smbus libjpeg-dev lirc

You could have a problem during lirc install, it's normal.

Code:
sudo -i pip install --upgrade pip setuptools
sudo -H pip install 'luma.core==1.13.0' 'luma.oled==3.4.0'

Add at the end of /boot/config.txt:
Code:
dtparam=spi=on
dtoverlay=gpio-ir,gpio_pin=4

Download and install oled and lirc files:
Code:
wget -O raspdacmini.tar "https://drive.google.com/uc?export=download&id=11W2kV4M55jKDbQk8qEkaiBZqKe6l0V_L"
tar xvf raspdacmini.tar
sudo chmod 755 oled/raspdac_oled_main.py
sudo chmod 644 oled/oled.service
sudo cp oled/oled.service /etc/systemd/system/
sudo systemctl enable oled
sudo cp -r lirc/* /etc/lirc
sudo cp serial.py /usr/local/lib/python2.7/dist-packages/luma/core/interface/serial.py
rm -r lirc
rm raspdacmini.tar

If you had problems during lirc install:
Code:
sudo apt-get install -f

Then reboot:
Code:
sudo reboot
