Sonos-HDMI by Retired Guy isn't outputting graphics...

Yes, I’m clearly struggling.

I started from the beginning and made sure I had the Hyperpixel 4 working. Screen was working well. I began following the HDMI directions for installing packages (even though I will be using your remote master.zip). I also installed pigpio and and evdev.

I moved the SD card back to my linux laptop and edited rc.local just above exit 0 as you recommended.

I have both /dev/fb0 and /dev/fb1 and my guess is the Hyperpixel is fb1. I tried googling but don’t see a clear way to change that.

When I rebooted after making the changes you suggested to rc.local I no longer have any screen output.

Right now when I run sonos.py I get the following error (I haven’t figured out how to make this a service yet, just trying to make it work first).

pi@raspberrypi:~/sonos $ python3 sonos.py

Is there a Sonos device at 192.168.68.128?  Doesn’t appear to be, soco is not finding one.  Those errors are way down in soco somewhere.

Make sure you change this in sonos.py, around line 24 to the IP address of the zone you want to monitor.

If your Hyperpixel is on fb1, change the Python script to write to /dev/fb1 instead of /dev/fb0.

########################################## Sonos zone to monitor -CHANGE ME! ##zone = soco.SoCo('192.168.68.128')########################################

IP updated!

May be on fb0, when I tried fb1 it reported the fb.seek no space error.

Getting this error now:

pi@raspberrypi:~/sonos $ python3 sonos.py

Thank you for your help. Gonna give it a bit of a rest. May try to make the HDMI version work on the screen tomorrow.
 

That’s the input device (touchscreen).  Yours may be 0. 
 

Change this line, about line 294:

dev = InputDevice('/dev/input/event1')

Change the 1 to 0. 

Wow thanks! I’m pretty close now. The display worked initially before going through installation steps but it’s remained blank since following reboot. This is the output as I started and stopped music to the sonos device:

pi@raspberrypi:~/sonos $ python3 sonos.py
screen brightness set
timeout started!
timeout cancelled!
screen brightness set
timeout started!
timeout cancelled!
timeout started!
 

So seems like things are working I just need to figure out why my display stopped working (light’s up but remains blank). I wonder if it’s pigpio related. I tried undoing these /etc/rc.local settings but the display didn’t turn on. IE I made these changes (and then changed them back when it didn’t solve my problem).

# Start pigpiod

# /usr/bin/pigpiod

# Turn off HDMI
# /usr/bin/tvservice -o

I also tried turning off the pigpiod service but screen didn’t turn on- I haven’t tried figuring out how to stop the service from running at boot.

Edit: seems like there is an issue starting the service:

pi@raspberrypi:~ $ systemctl start hyperpixel-init

I’m going to try and install again via “curl -sSL https://get.pimoroni.com/hyperpixel4 | bash”.

Might be an issue after running sudo apt-get update. I’m going to try to go to an older stable install.

This didn’t work:

sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel

I’m going to do give more try at rolling back the kernel and then start from scratch.

I haven’t migrated to bullseye yet, still on buster. Looks like there are issues with the Hyperpixel on bullseye. Haven’t read the entire thread on GitHub, perhaps they’ve resolved it by now?

https://github.com/pimoroni/hyperpixel4/issues/155

Screen is now working! I shouldn’t have updated the kernel. Thank you so much for helping me through it!

I started from scratch without updating and all is well now. Thank you!

Good show!  
 

BTW, I’ve moved to the Oswald font for the Squeezelite version of this, as it provides a whole lot more text in the given space. 
 

https://github.com/retired-guy/Squeezebox-3.5/blob/main/sb.py

For anyone that wants to get Sonos-Remote working, a few extra commands in addition to changing code in the files mentioned above:

curl -sSL https://get.pimoroni.com/hyperpixel4 | bash

Sudo apt-get install python3-pigpio

Pip3 install evdev

And for the sonos.service file to make it work at startup:

[Unit]
