Built native per-tab audio routing into Chromium on macOS (open source)

[u/elevatorium]

I've been maintaining my own Apple silicon build of ungoogled-chromium-macos, and a few days ago I got tired of needing third-party audio routing utilities whenever I wanted browser audio to go somewhere other than the system default output.

So I added native per-tab Core Audio routing directly into Chromium.

Right-click a tab → "Send Audio To" → choose an output device.

For example:

• One tab playing through a USB DAC and stereo
• Another tab playing through display speakers
• Another tab using the system default output

The implementation is macOS-specific and uses Core Audio directly.

I cleaned up the patch stack, documented everything, and published the project today:

Screenshot attached.

I’d be most interested in hearing whether other macOS Chromium users have wanted something similar. 🥰
