How to reproduce:
1. Open attached project "AudioSource-PlayScheduled-BugReport.zip" and scene "SampleScene"
2. Make sure to lower the sound of Unity or the Audio Source components
3. Enter Play mode
4. In hierarchy, select "GameObject" object
5. In Inspector, "Audio High Pass Filter" -> change Cutoff Frequency to 10
6. Observe the sound
7. In Inspector, remove "Audio High Pass Filter" component
8. Observe the sound

Expected result: the two different sounds play at the same intervals, the step 6 sound is the same as in step 8
Actual result: the sound plays at different/random intervals with random variation in the sounds, the step 6 sound is not the same as in step 8
