Plugin attenuates other sounds on Windows when it shouldn't

[kubaau]

Describe the bug

1. Start some music in background.
2. Set Windows to attenuate sounds by 80% when it detects communication in the sound control panel.
3. Connect to conference.
4. Disconnect from conference.
5. Connect again.
6. Set Windows to do nothing when it detects communication.
7. Music volume is still lower, incorrectly. Possible to completely silence the music, but not to have it at 100% nor 50%. Need to disconnect while "Do nothing" is selected and reconnect to fix.

And more simply: if you quit the conference and reconnect with sound attenuated, you cannot disable the attenuation mid-conference.

Another, related reproduction scenario is:

1. Start some music in background.
2. Set Windows to attenuate sounds by 80% when it detects communication in the sound control panel.
3. Connect to conference.
4. Quit game in editor.
5. Reopen game, don't join conference.
6. Music volume is lowered, incorrectly, even though we are not even in conference.

Expected Behavior

Music volume should never be lowered out of conference.

AND

Either:

• music volume should not be lower when setting "Do nothing" (and should work correctly with other settings as well)
  or
• music volume should never be lower (plugin sound should not be detected as communication by Windows)

Minimalistic code (recommended)

N/A

Specifications

• OS: Windows
• Version:

[kubaau]

This is a problem of an underlying component which will deliver a fix "in the next week". The plugin will follow soon after.

[kubaau]

Fixed in release 1.0.1.

[kubaau]

Apparently not fixed after all.

[kubaau]

The issue now seems to occur only when the output device is also the default communications device.

[kubaau]

Will be fixed in 1.1.0-beta.4 or 1.1.0 and probably in 1.0.2.
