The following code can be downloaded directly to your Raspberry Pi. It will read the trimpot value, translate the reading to a volume range and modify the OS output volume level on your Raspberry Pi. The remap_range () method is being used to convert the 16-bit analog in range 0 - 65,535 to volume 0-100%.

If you are unsure what to choose here, select “yes”. When you’re asked to reboot the Raspberry Pi, select “yes” and then run the script again. You’ll now be asked to test the audio. The easiest way to do this is to plug some powered speakers or some headphones into the 3.5mm stereo socket on the I2S Stereo Decoder.

Teaching the Raspberry Pi how to read analog inputs is easier than you think! The Pi does not include a hardware analog-to-digital converter, but an external ADC (such as the MCP3008) can be used, along with some SPI code in Python to read external analog devices.. Here is a short list of some analog inputs that could be used with this setup:
