Is the on-chip volume control on the ES9028/38 supported by Moode??

[Tim Curtis]

Hi,

Software volume only. moOde just uses a generic I2S driver (hifiberry-dac or rpi-dac) for the Audiophonics boards because AFAIK, Audiophonics has never submitted ESS drivers for acceptance in mainline Linux kernel.

Below is list of all driver overlays present in latest kernel.

Code:
