Repair logic

The issue is often caused by Windows audio settings or driver conflicts that interfere with Adobe Premiere's audio output. By disabling mono audio accessibility, turning off audio enhancements and spatial sound, and ensuring audio drivers are up to date, the audio will remain stereo and stable when launching Premiere. Reviewing Event Viewer logs helps identify underlying errors if the problem persists.

FAQ

Why does my audio switch to mono only when I open Adobe Premiere?

Adobe Premiere may interact with Windows audio settings or device drivers in a way that triggers mono audio or disables stereo enhancements, often due to incompatible driver versions or enabled audio enhancements.

Can Windows audio accessibility settings cause this problem?

Yes, if 'Mono audio' is enabled in Windows accessibility settings, it forces all audio to mono system-wide, which can be triggered or noticed when launching resource-intensive apps like Adobe Premiere.

How do I know if my audio drivers are causing the issue?

Using Device Manager, check if your audio drivers are outdated or have errors. Updating or reinstalling drivers often resolves conflicts causing audio to switch to mono or disappear.
