Welcome to Microsoft Q&A and thanks for sharing the details. I know how annoying it can be when your music or call audio suddenly drops while you’re in a meeting or voice chat.
Here are a few things you can try that usually fix this issue:
Step1: Turn Off Exclusive Mode for Audio Devices
This prevents apps from taking full control of your audio device, which can cause other sounds to lower.
- Right-click the speaker icon → Sounds → Playback tab.
- Select your default output device → Properties → Advanced tab.
- Uncheck:
- Allow applications to take exclusive control of this device
- Give exclusive mode applications priority
- Do the same for your microphone under the Recording tab.
- Allow applications to take exclusive control of this device
Step 2: Check App Volume and Disable Enhancements
Sometimes Windows or apps adjust volume automatically or apply effects that interfere with playback:
- Go to Settings → System → Sound → Volume Mixer and make sure Spotify, Discord, and your browser (for Google Meet) aren’t being auto-adjusted.
- Under Advanced sound options, review App volume and device preferences.
- In your device properties, turn off Spatial Sound and any Enhancements like Loudness Equalization.
Step 3: Turn Off Game Bar and Focus Assist
These features can sometimes trigger audio changes during calls or gaming. Please try:
- Disable Game Bar: Settings → Gaming → Xbox Game Bar → Off.
- Disable Focus Assist: Settings → System → Focus Assist → Off.
Step 4: Adjust Discord Settings
Discord’s audio settings can affect how Windows handles sound:
- In Discord → User Settings → Voice & Video:
- Turn off Enable Quality of Service High Packet Priority.
- Switch Audio Subsystem from Standard to Legacy (or vice versa).
- Temporarily disable Echo Cancellation / Noise Suppression to test.
- Switch Audio Subsystem from Standard to Legacy (or vice versa).
- Turn off Enable Quality of Service High Packet Priority.
Step 5: Advanced Option: Registry Change
This changes Windows’ hidden setting that controls audio ducking:
- Open Registry Editor and go to:
HKEY_CURRENT_USER\Software\Microsoft\Multimedia\Audio - Find
UserDuckingPreferenceand set it to:-
0= Reduce by 50% -
1= Mute -
2= Do Nothing
-
- Restart your PC after making the change.
Disclaimer: Generally, modifying registry subkeys or work groups is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
