So I've been noticing this for possibly a good while already but it seems that whenever I activated Windows Magnifier it tends to interfere with NVDA's audio ducking capability.

Steps to reproduce:

1. Have some sort of audio playing in the background, for example an audio game or a music file.
2. Use the NVDA hotkey (by default it is NVDA+shift+d) to switch audio ducking mode to always duck.
3. Activate Windows Magnifier by pressing the Windows+= hotkey.

Actual behavior:

NVDA no longer ducks the audio, even though in the settings dialog the audio ducking mode has not change. Or sometimes NVDA would just only duck audio when outputting speech, even when audio ducking mode is set to always duck.

Expected behavior:

When using the always duck audio ducking mode, NVDA should continue to duck all audio even when Windows Magnifier is activated.
