Get SoundSource 6.2 Today

SoundSource continues to make your Mac’s audio even better

SoundSource 6.2 is here, bringing a host of improvements in another free update. There’s more efficient audio handling, improved compatibility with AirPods and Game Mode, and interface refinements throughout the app. Read on for the highlights, or download this free update immediately.

New in SoundSource 6.2

With almost two dozen improvements, SoundSource 6.2 is faster, more efficient, and more polished than ever. Here are some highlights.

Better Audio Handling, With Less Overhead

The most notable changes are in the ARK plugin, which powers SoundSource’s audio handling. We’ve substantially improved its efficiency, helping SoundSource use less CPU and memory, particularly when idle. We’ve also enhanced compatibility with MacOS’s Game Mode and AirPods with Head Tracking enabled, eliminating issues that could previously interfere with audio playback.

SoundSource is designed to run all day, every day, and these improvements help it do so with even less impact on your Mac.

Improved Audio Unit Controls

SoundSource makes it easy to apply Audio Unit effects to any audio on your Mac. With version 6.2, working with those effects is easier than ever. The generic Audio Unit interface now organizes parameters into groups, making complex effects easier to manage. Even better, you can use Command-F to quickly filter the list of parameters and find exactly the control you need. These changes are particularly welcome when working with Audio Units that offer dozens, or even hundreds, of adjustable parameters.

Interface and Accessibility Improvements

You’ll also find interface improvements throughout SoundSource. We’ve smoothed animations, improved responsiveness, and eliminated several visual glitches. Of particular note, SoundSource’s minimize animation (seen when unpinning the main window) has been made at least 43% more fun.

We’ve also worked to make SoundSource more accessible and easier to use. VoiceOver support has been reviewed and refined throughout the app, and we’ve polished the interface for new touch input on the Mac. We anticipate making further improvements in the future, so if you have any feedback, don’t hesitate to reach out.

Airfoil Streaming to Apple TVs and HomePods Is Restored!

Airfoil now streams to Apple TVs and HomePods running the latest software.

Today, we’re very glad to announce a free update to Airfoil, our home audio streamer. The new version 5.13 restores the app’s ability to stream audio to all Apple TV and HomePod devices. Previously, the tvOS 27 and HomePod OS 27 updates introduced an issue which prevented that streaming from working.

Fortunately, we were eventually able to develop a workaround for this issue. Audio is now flowing to these devices once again. Airfoil 5.13 is now available for all Airfoil users on MacOS 14.4 and higher. Get it now by selecting Check for Updates from the Airfoil menu. Happy streaming!

MacOS 27 Fixes Multiple Audio Bugs

Apple’s latest OS provides the best audio performance on your Mac.

Apple has now released MacOS 27 (Golden Gate), and all of our products support this latest version of the Mac’s operating system. We’ve already issued a couple of quick updates to SoundSource, to fix problems which arose with the official OS release. At present, we’re keeping an eye out for any further issues.

We’re also already recommending upgrading your Mac to Golden Gate. The new OS includes several important audio improvements, and as a result, Golden Gate provides the best experience when using our apps. Below, you’ll find details on key bug fixes Apple included in MacOS 27.

  • Issues which led to excessive CPU consumption have been eliminated

    MacOS’s underlying “coreaudio” system makes extensive use of aggregate device technology to handle audio. In the past, there were a handful of bugs which negatively impacted the system when working with audio.

    Golden Gate features improvements to how those aggregate devices are managed. These changes have eliminated multiple problems which could lead to excessive CPU usage when capturing audio. This is likely to most noticeable for SoundSource, but all of our products will benefit.

  • Audio capture is now more reliable, particularly with VOIP apps

    MacOS 26 (Tahoe) contained a backend bug which could prevent application audio from being captured when using two different devices for input and output. This configuration is most commonly seen with VOIP applications like Zoom or FaceTime, and the result was that audio captures would unexpectedly lead to silence.

    This bug is resolved on Golden Gate, and these captures should always work as expected.

  • CPU usage reductions and the elimination of hangs

    On both MacOS 15 (Sequoia) and MacOS 26 (Tahoe), another issue with MacOS’s audio system could lead to high CPU usage. This problem manifested when SoundSource launched and setup, as well as when other applications began playing audio. In the worst cases, the issue could even lead the system to hang, necessitating a restart.

    Thankfully, MacOS 27 has eliminated this bug. As a result, the amount of CPU SoundSource uses is reduced, and those hangs are eliminated.

Another Notable Improvement in MacOS 27

Back in January, we posted about the extraneous icons on menu items found in MacOS 26 (Tahoe). We’re quite pleased that Apple has scaled these icons way back in Golden Gate. Next, perhaps app icons can once again be permitted to have distinct shapes?

With these notable bugs fixed in Golden Gate, it’s already worth considering upgrading your computer to MacOS 27.0. Of course, we also recommend using the latest versions of our own products, by selecting Check for Updates from within the app.

Problems Streaming to Apple TVs and HomePods with Airfoil

The tvOS 27 and HomePod OS 27 updates may break your setup.

This Issue Has Been Resolved

After much hard work, we were eventually able to develop a workaround for this issue. Be sure to update to the latest Airfoil. For more, see the follow-up blog post.


With Apple now having announced a September 14 release date for this fall’s OS updates, we need to issue a warning to users of Airfoil. Unfortunately, Apple’s forthcoming tvOS 27 and HomePod OS 27 updates contain a critical bug that prevents Apple TVs and HomePods from playing AirPlay streams sent by Airfoil. If your devices update to the OS 27 versions, Airfoil will no longer be able to stream to them.

We have created a support article with more information. If you use Airfoil to stream to an Apple TV or a HomePod, we strongly encourage you to read it. It contains more details on the issue, as well as useful instructions for preventing your devices from automatically updating.

Consider SoundSource for AirPlay streaming from your Mac

Of special note, that page has details on using SoundSource to stream from your Mac to AirPlay devices. Because SoundSource streams via a very different mechanism than Airfoil, it is unaffected by the aforementioned bug.

With the AirPlay functionality added in version 6, SoundSource has proven to be a very capable home streaming tool.
