What's new in version 6.1.2

New

Preliminary Support for MacOS 27 (Golden Gate) Betas. SoundSource no longer warns on launch when run on MacOS 27 (Golden Gate). There are no known issues on Golden Gate at present.
Do note that Apple’s betas remain in flux. We always encourage users to stick with official (non-beta) OS releases for the best experience.
Several AirPlay Enhancements. Several improvements have been made to SoundSource’s AirPlay streaming.
SoundSource now reliably auto-connects to AirPlay devices when sending audio to them.
Output Groups and AirPlay devices now correctly re-establish themselves after a restart of coreaudiod.
Synchronization between AirPlay devices has been tightened, correcting audible drift that could occur when streaming to multiple outputs for extended periods of time.
A “UID already exists” error which could occur when connecting to AirPlay devices has been corrected.
The last-used volume for AirPlay devices is now restored upon connecting.
Processing of silence has been greatly optimized, so average CPU usage is greatly reduced.
SoundSource’s Shortcuts will once again be shown within Apple’s “Shortcuts” app, without requiring a system restart to appear. This fixes a regression introduced in SoundSource 6.1.0.
SoundSource now works correctly with the Mixed In Key “SE” Audio Unit plugin.
Multiple sources will no longer appear in SoundSource for the same process. This avoids issues where audio could be doubled.
When previewing media with Quick Look in the Finder, audio is no longer incorrectly doubled (and thus un-mutable).
Improvements have been made to avoid audio from Loopback virtual devices being muted for as long as 10 seconds after the device is no longer being captured by another application.
A rare crash that could bring down SoundSource while it was running in the background has been fixed.
Interface elements which could appear blurry on non-retina displays should now be crisp.
Effect popovers now retain their position when opened via the “Open/Close Effect Window” shortcut.
Fresh instances of Audio Unit effects are once again displayed at their initial default size. This fixes a regression introduced in SoundSource 6.1.1.
SoundSource will no longer incorrectly appear over the menu bar when “Automatically hide and show the menu bar” is enabled in System Settings.
The “Local Network Accession” permission will no longer incorrectly cycle between enabled and denied.
SoundSource’s icon has been updated to support the system-wide Dark icon style on MacOS 26 and higher.

Soundsource v.5.8.13 has a memory leak on my M1 Mini and takes up to 1.2 GB of RAM while running. I downgraded to 5.8.12 and it uses what it always did - around 700 MB of RAM. They want me us to upgrade to v6, but the concern about the memory on my 8 GB Mini makes me wary of doing that. So instead, I installed FineTune, which does almost all of wht SoundSource did, using under 50 MB of RAM after running for a few days. Less filling, tastes great, as the saying goes.

4.0.2

Version: 4.0.2

I’ve just upgraded to this software from its previous version and can’t therefore write a concrete review for it. It’s simply impossible to evaluate a program after a few hours of usage. However, computer applications are like shoes. They either fit instantly, and you feel comfortable wearing them from the very beginning or you might just break them in for months and end up with a pair of awkward shoes! Having said that, I’m very pleased with the performance of this new version of SoundSource. Compared to the previous version it now has everything I ever dreamt of to organize my audio sources. The interface is intuitive and very well structured. All commands are where they are supposed to be, and this means a lot to me when switching audio sources continuously. The sound is great and contrary to its competitors it’s rock-solid and doesn’t quit unexpectedly every now and then. As I mentioned before, it’s hard to evaluate all its functions in such a short time therefore, trying is believing! Fariborz AMIRSHAHI - Verona (Italy)
