Switching between multiple monitoring devices can be a bit of a hassle and can often take a lot of clicking around to switch over. For that reason, we have introduced a brand new automation logic to the system output device selection with Systemwide 4.3. The Default Output Device feature is intended to perform at it's best in combination with the new User Presets feature in 4.4 software release.
There are two key features to the new functionality - automatic system output take-over and an advanced output device management within Systemwide (the output settings you assign in Systemwide to complete the signal chain - your actual physical output). New notification support is also in place to keep you in control and informed, this will allow you to keep the monitoring experience smooth and seamless.
The automatic take-over is simple - Systemwide will always set itself as the system audio output device when launched. It will also revert to itself as the default output device if you're trying to select a different one. The automatic take-over is ON by default but you can always turn it OFF in case your setup is not playing well with it. Find the 'Keep Systemwide the default system output device' checkbox in Systemwide settings. It is important to know that if you have this setting turned OFF, it will stay off - the actions you take with notifications (described below) will never affect Systemwide settings permanently.
If the automatic take-over is turned OFF, changing the system output will trigger a notification. This notification will contain a couple of choices: do nothing, or set the chosen device as output in Systemwide (NOT taking over the system output either way). A smaller checkbox will also give you the option to take over system output THIS TIME ONLY.
There will be smaller informative notifications too, all of these can be turned off in Systemwide settings. But you'll probably want to finalize your monitoring flow first, before turning off the unwanted notification.
