Audio.PlayScheduled produces artifacts on cpu spikes
To reproduce:
1. Import package the "repro"
2. Open "scene"
3. Enter play mode
4. Press space. it should call "audio.PlayScheduled" and play the sound after 1 second, but it sometimes plays a small part of the sound instantly, which should not happen. This is due to a cpu spike (in this case caused by debug log calls)

I'm having the issue on Unity5.1 Android
I found out another workaround which is using LoadInBackground as if it were preloaded: http://answers.unity3d.com/questions/971559/why-does-audiosourceplayscheduled-play-for-an-inst.html#answer-1184468

Still having this issue on 5.1.0f3. On Android, it plays for milisseconds, then stops, and then continues from where it should continue. This issue is making the song of my game playing too badly on my phone.

I can still this issue on 5.1.3f1.
A partial workaround can be found here: http://answers.unity3d.com/questions/971559/why-does-audiosourceplayscheduled-play-for-an-inst.html
The workaround creates another issue, less ever then this one.

I confirm the problem with 4.6.1. But now is less severe, I have the problem only with the android building, the editor works great now (it wasn't the case with unity 4.5).

I'm trying to create a rhythm game for android. On some PC it works great, but on my laptop I get this problem. On android I also get this problem. Logging seems to trigger the problem on PC, but it occurs regardless of logging on android.
Please let us know the progress on the issue -- I'll need to scrap this game or use a different engine altogether with this bug present.

I've had this for a long time, and it's really getting in the way for my music work in Unity.

I'm experiencing this issue as well and it's definitely a regression. I believe it was introduced in version 4.1 or 4.2.

I noticed this as well. My workaround was to set volume to 0. Once the clip has passed this initial load period you can set volume back to your default volume and PlayScheduled will work fine.
But PlayScheduled also hiccups occassionally. I'm not sure if this is a buffering issue or not. If it is a buffering issue I haven't figured out a workaround to guarantee pre-buffering in time.
