Installation

We will build and install the driver using DKMS.

Before you start, define the TauDAC version variable:

export taudacver=2.5.0

You can then use $taudacver in the commands below. Adjust the version if you're installing a different release.

Preparation

Download and unzip the driver source directory:

wget https://github.com/taudac/taudac-driver-dkms/archive/taudac-${taudacver}.tar.gz
tar -xzf taudac-${taudacver}.tar.gz

Copy the driver source to a directory where DKMS can find it:

sudo cp -r taudac-driver-dkms-taudac-${taudacver} /usr/src/taudac-${taudacver}

Install the build dependencies:

sudo apt-get install dkms build-essential

Installing the Kernel Headers

To build the driver, we need to install the kernel headers. The method depends on your distribution.

Raspbian / Raspberry Pi OS:

sudo apt-get install linux-headers-$(uname -r)

Please be patient, "Unpacking raspberrypi-kernel-headers" might take a while...

Volumio:

sudo volumio kernelsource

Building and Installing

Build and install the driver using DKMS:

sudo dkms install -m taudac -v ${taudacver} --force

Uninstalling

Uninstall the driver using DKMS:

sudo dkms remove -m taudac -v ${taudacver} --all

Configuration

The Raspberry Pi audio driver (snd_bcm2835) can be disabled by commenting out the following entry in /boot/config.txt:
