ACT TTS ignores windows volume settings

[xpdota]

1. Install OverlayPlugin or anything else that would utilize ACT's builtin TTS.
2. Mute ACT's volume in the windows volume mixer.
3. Trigger a TTS.

Expected: You hear nothing
Actual: You hear TTS, even though the volume is muted and the bar is grayed out:

In addition, when merely altering the volume rather than muting, a TTS causes the volume to pop back up to its previous setting.

This is an artifact of the Windows Media Player API. It changes the host application's volume to the volume it is instructed to play a sound at. This cannot be fixed inside of ACT. You either need to use the volume sliders inside of ACT, or use a sound engine other than WMP API. (or see if Microsoft wants to fix it)

Looks like this is fixed with the new SAPI setting, thanks!

Just be aware that playing sound files outside of OverlayPlugin's CEF process will still have this behavior. The only workaround is to use a different sound engine like Windows API or XAudio2.
