On Windows, fixed a few related bugs where if the Unity project/player settings were set to the Quad speaker mode, we would still output sound to the front center channel on a 5.1 or 7.1 system. Similarly, if Unity is set to use the surround (5.0) speaker mode, we would still output sound to the LFE channel on a 5.1 or 7.1 system. This has now been fixed for both mono and multi-channel sounds.
Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.
How to reproduce:
1. Connect the 5.1 speakers system
2. Setup the speakers in Settings -> Sound -> Sound Control Panel -> right-click on the speaker -> Configure Speakers so the surround sound would be enabled
3. Open the "IN_53087" project
4. Enter the "SampleScene"
5. Make sure "Quad" is selected in the Project Settings -> Audio -> Default Speaker Mode
6. Enter the Play Mode
Expected result: Center speaker is not playing
Actual result: Center speaker is playing
