Multichannel Duplex Audio Interface No Sound from Proton (Focusrite Scarlett 18i20 + Pipewire)

In this article, we will explore the issue of no sound from a multichannel duplex audio interface when using Proton with a specific setup. The setup consists of a Focusrite Scarlett Gen2 18i20 audio interface, Pipewire 1.2.7, and Proton 9.0.4 on a Manjaro Linux system with OS version 6.13.5-2. We will delve into the details of the issue, provide relevant information, and attempt to find a solution.

When running Proton games, such as Baldur's Gate 3, there is no sound output to the Focusrite Scarlett 18i20 audio interface. The device is not detected by Proton, and no audio stream is visible in the Pipewire graph. However, when the default audio interface is changed to a different device, such as the onboard motherboard or a USB audio interface, audio works as expected. This suggests that there is an issue with the way Proton interacts with the multichannel duplex audio interface.

Here are the relevant system details:

OS: Manjaro Linux 6.13.5-2
Steam: 1741737356
Proton: 9.0.4
Audio interface: Focusrite Scarlett Gen2 18i20
Pipewire: 1.2.7

The game log and system info files are attached to this article:

When running the game with the default audio interface set to the onboard motherboard or a USB audio interface, the Pipewire graph shows an audio stream. However, when the audio interface is set to the Focusrite Scarlett 18i20, no audio stream is visible in the graph.

Based on the information provided, it appears that there is an issue with the way Proton interacts with the multichannel duplex audio interface. Here are some possible solutions:

Update Proton: Ensure that Proton is up-to-date, as newer versions may resolve this issue.
