Geek Out and Raspberry pi

Hi there,

I am running the LH labs Geek Out DAC with firmware 1.5 but am unable to use the hardware control. The dac just sits at 100% volume and is not adjustable. The software controlled volume works but significantly degrades quality. Any suggestions on how to implement hardware control or anything that I could try?

Best wishes


The DAC uses the ESS 9018K2M DAC chip.

Many thanks
