Valve Hardware Audio Processing

This repository contains any and all customizations audio configuration and processing we run on the Steam Deck.

This includes:

1. Configurations for source and sink setups in Pipewire for Voyager/Jupiter and Galileo.
2. Wireplumber scripts for routing those sources/sinks for Voyager/Jupiter and Galileo.
3. Individual UCM configs for session policy for Voyager/Jupiter (coupled with the acp5x soundcard) and Galileo (coupled with the sof-nau8821-max soundcard)
4. Faust scripts for generating a statically compiled speaker and microphone tuning.
5. Prebuilt and presigned SOF firmware binaries for the audio co-processor on Galileo.
6. Scripts and a submodule setup for compiling an unsigned version of the SOF firmware binary for Galileo from source.

Setup and Install

Generally, to build this package we require the following packages:

Arch Linux:

1. base-devel
2. glibc
3. faust
4. ladspa
5. lv2
6. boost
7. linux-api-headers
8. qt5-base

Debian:

1. build-essential
2. faust
3. ladspa-sdk
4. lv2-dev
5. libboost-all-dev
6. qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools

With these installed, you can compile lv2 plugins from our faust scripts using make:

make FAUSTINC="/usr/include/faust" FAUSTLIB="/usr/share/faust"

Note: on Debian it seems you have to pass in the SHELL:

make SHELL="/bin/bash" FAUSTINC="/usr/include/faust" FAUSTLIB="/usr/share/faust"

These can be installed to the current device using sudo make intall. Alternatively, they can be installed to a pacman-style pkg directory like so:

make DEST_DIR="$pkgdir/" install
