| An app that plays a notification sound stays in the collapsed app list for five minutes. |
Expand the list or pin the apps you adjust. |
| When an app starts a new helper process on the same output, it can play briefly at its unadjusted volume. |
Keep the system volume at a comfortable level. |
| An app that plays to a second output, such as a call ringing on speakers, is controlled on the system output only. |
Set the app’s ringer or second device to the system output. |
| After editing a Multi-Output device in Audio MIDI Setup, apps playing on it stay unadjusted. |
Pause and resume playback in the app. |
| Multi-Output devices of two physical outputs are untested. Members may drift or echo. |
Use a single output. |
| Routing an app to an AirPlay receiver that is not the system output is untested. |
Make the AirPlay receiver the system output. |
| A USB audio interface that resets interrupts processed audio until Unsound restarts it. |
Wait a few seconds. If the app stays silent, click Retry in its row. |
| After restarting the browser or extension, controlled tabs need enabling again. |
Click the Unsound toolbar button on each tab. |
| Play and pause are verified with Spotify and Music only. |
Use the player’s own controls. |
