Yes indeed, toggling sound to the HDMI port helped. Please use raspi-config – it’s under Advanced Options -> Audio. Then reboot. Afterwards the AO should be working fine.

Let me know.

Hi Ben,
thanks for reporting this. I can confirm the problem. With full Raspbian, the output is always at 10V. With Raspbian Lite, everything is working fine. I suspect there is some collision with audio in the full Raspbian. I will continue digging...

Unip v1.1 board Analog output

2017-01-04T01:21:44Z

Hello all
Happy New year!!
I am working on 2 unipi v1.1 boards, I can not get the analog output working with Rex UnpDrv, the AO output stay at 10Vdc as soon as upload the UnpDrv with a simple function block, all other input and relay output are working, but can not control the AO, I test the boards with Python PWM function, both boards are working fine.
Has anyone have the same problem or can anyone help please?
