Did you receive any errors? Check the log file at /var/log/pydPiper.log and see if anything is reported there.

It looks like their was a version change for docker that is broken on the RPi. Try issuing the following to downgrade to the prior version.

sudo apt-get install -y --force-yes docker-ce=17.09.0~ce-0~raspbian

Then reboot and see if it comes back up successfully.

Hello, I ran into the same issue with broken docker. After downgrading and reboot, my pydPiper.log gave this:

2017-11-27 21:24:28,803:INFO:pydPiper starting 2017-11-27 21:24:29,020:ERROR:Uncaught exception Traceback (most recent call last): File "/app/pydPiper.py", line 615, in lcd = displays.hd44780_i2c.hd44780_i2c(rows, cols, i2c_address, i2c_port) File "/app/displays/hd44780_i2c.py", line 134, in init self.write4bits(0x33,False) File "/app/displays/hd44780_i2c.py", line 160, in write4bits self.bus.write_byte(self.i2c_addr, bits_high) IOError: [Errno 121] Remote I/O error 2017-11-27 21:24:40,635:INFO:pydPiper starting 2017-11-27 21:24:40,747:ERROR:Uncaught exception Traceback (most recent call last): File "/app/pydPiper.py", line 615, in lcd = displays.hd44780_i2c.hd44780_i2c(rows, cols, i2c_address, i2c_port) File "/app/displays/hd44780_i2c.py", line 134, in init self.write4bits(0x33,False) File "/app/displays/hd44780_i2c.py", line 160, in write4bits self.bus.write_byte(self.i2c_addr, bits_high) IOError: [Errno 121] Remote I/O error

Does it mean that I have chosen the wrong display ? If so, how do I perform a re-install with the correct display. I had some hesitation between the hd4778 and the Winstar WEH display. I bought it at Audiophonics.fr at january. Thanks in advance and keep on the good work. PB

Yes, this error would be caused by the selection of the wrong display type. If you have the Raspdac from Audiophonics, you have a Winstar WEH display. There is an example of the correct ExecStart for it in the pydpiper.service file. If not, let me know what you did purchase and I’ll give you a specific example for your system.

hi dhrone,

Thank you for your reply. I can only find an example for Winstar WEG display only in the pydpiper.service file, not for WEH display. I bought this at Audiophonics:

https://www.audiophonics.fr/fr/dac-diy/audiophonics-i-sabre-dac-es9023-v3-tcxo-raspberry-pi-20-a-b-i2s-p-10657.html

My DAC is the V3 Generation 2. I also have a problem with docker, it does not start after a second reboot. Do I have to re-run install.sh.

Regard,

PB

Hi dhrone, I managed to solve the problems. It's all working now. You were right about the Winstar WEH driver, I use: ExecStart of "# RaspdacV3 without weather" Here how I solved it by making a fresh install of docker:

1- Remove docker : sudo apt-get purge docker-ce sudo apt-get autoremove rm -rf /var/lib/docker # This deletes all images, containers, and volumes

2- Re-install docker: sudo apt-get install -y --force-yes docker-ce=17.09.0~ce-0~raspbian

3- Check if it works: docker run armhf/hello-world

4- Make volumio member of docker group" sudo usermod -aG docker volumio

5- Then the rest from install.sh:

sudo systemctl enable docker sudo systemctl start docker sudo docker pull dhrone/pydpiper:v0.31-alpha sudo cp pydpiper.service /etc/systemd/system sudo systemctl enable pydpiper sudo systemctl start pydpiper

I hope this can help another people who ran in the same corrupted installation. Thanks for your tip about the driver.

[dhrone]

Excellent work. I'll revise the instructions and the install script after a few tests.

i have it running now without docker, since I am experimenting a lot with settings and displays and it works perfectly! thanks a lot!
