Hi @abzolv,
I saw a similar report recently where disabling audio enhancements in Windows actually helped stop this from happening. Would you mind giving that a try to see if it makes a difference for you? You can disable enhancements using the steps below:
1. Open the Windows Control Panel
2. Click Hardware and Sound
3. Click Sound to open the Sound Properties window
4. Right-click your default sound device (it will have a green check mark)
5. Click Properties
6. Click the Enhancements tab
7. Check the box that says Disable all enhancements
8. Click Apply, then click OK
Try running Apex Legends again after that. Let me know if you're still seeing any freezing or stuttering afterward. Thanks!
