Instruction Guide 128x64 OLED with Song Status and Spectrum Display on Raspberry Pi
Hi The Herb Guy

Thank you for your description of the problem.

If you added a line to /boot/config.txt like 'dtparam=i2c_arm_baudrate=400000', could you try removing it.

Does it make any difference if you specify your DAC is a IQaudiO DAC+?

Here is another link about I2C with this DAC chip: https://e2e.ti.com/support/audio/f/6/t/538530

It makes me wonder if it is worth writing to the DAC board manufacturer to ask if I2C is meant to be available to other devices, and whether it requires any configuration to make it available.

[EDIT]... or search the internet for someone else who has the same or similar DAC board and is using another I2C device with it and find out if they did anything special to enable this.

Adrian.
