Volume Randomly Jumps On Its Own with Rotary Encoder (without Breakout)

[BzowK]

Hey Guys -

90% done building this for my 2 year old daughter - just have one issue I cannot resolve. My installation is fairly simple as it's a RasPi3 with the following components:

• MFC522 RFID Reader
• USB powered Speakers
• C-Media USB Audio Card
• Rotary Encoder without Breakout (CYT1100)

After config, everything works correctly except the rotary encoder. When its enabled in Settings, the volume dynamically jumps up and down without me touching it. I followed all steps in the Wiki plus these steps to install the service and such. I even tried commenting out all lines in gpio-buttons.py dealing with volume to no avail. Same thing occurs if i swap the two Out pins. When it's disabled in settings, the behavior stops, so know it's related to the encoder, itself.

My best guess is that it is because I am using a rotary encoder without breakout therefore has slightly different pins having two grounds, a switch, and 2 outs. Here's a quick sketch I made of how its attached where the switch & outs are on the default GPIOs.

I've looked all through issues and cannot find anything similar. Below are additional build specs. Any suggestions would be appreciated. Thanks!

What's the result of journalctl -u mopidy?

[BzowK]

Thanks for the reply - output is below. To note, the rotary encoder is disconnected and I removed the service temporarially. Can hook back up and run again if needed.

The mopidy installation looks broken.

Please check with ls -l ~/phoniebox_logs/ for existing logs of the installation script and post the content of the latest log here.

Thanks again for the reply...

Attached is the only log listed. If performing a 2nd installation from scratch is suggested or would be easier, I'll do so. To note, when installing rotary encoder service, I found some of the files it mentions adding in this post already existed so wasn't sure which to use (although I tested using both and got the same issue.) Thanks!

I resolved this by using a different type of rotary encoder - the one recommended. Thanks
