Unity does not recognize surround sound driver capabilities and plays audio in stereo



Reproduction steps:
1. Download and open the attached project: ""
2. Enter Play Mode
3. Observe the Console and listen to the recording playing in the background

Expected result: The sound is played in 5.1 surround sound and both Console messages output "Mode5point1"
Actual result: The sound is played in stereo and AudioSettings.driverCapabilites returns "Stereo" while AudioSettings.speakerMode returns "Mode5poin1"

Reproducible with: 2019.4.34f1, 2020.3.25f1, 2021.2.7f1, 2022.1.0b2

- Reproduced on Windows and Ubuntu 18.04
- Tested with surround sound capable hardware and appropriate drivers installed
- The same audio file played in the VLC media player, for instance, outputs proper 5.1 surround sound
- Reproduced in Editor and Player
- Another report mentioned the same issue with 7.1 surround sound but only on Linux

  1. Resolution Note (fix version 2023.3.0a1):

    Fixed a bug with surround sound hardware not being detected on Linux. Fixed an issue on Windows where we would not re-init audio output correctly, when the Unity project requested surround sound, and the Editor or player was started with no such hardware available. When surround sound hardware is later enabled and set as the default output, it will now be used.

    Is it a joke? Still there in latest version...
    Was deadly blocking for us.

    Same issue here.

    I'd need a fix urgently please. I'm totally blocked int the implementation of my audio for a project as a sound designer. Please keep us informed of any improvement.

    Thanks a lot in advance.
