When I started APEX for the first time in a while, I could no longer select 7.1ch or 5.1ch on the audio settings screen, and even if I set DTS Headphone:X or Windows Sibuc for Headphones, it no longer worked.
I tried the following, but it didn't fix it.
Repair APEX from the EA app
Run the Windows Audio Playback Troubleshooter
Turn off surround sound and start the game, then enable it after starting
Use Windows Sonic for Headphones
Disable "Exclusive Mode" in Windows Audio Settings
Change 48000 Hz to 44100 Hz in Windows Audio Settings
Use other headphones
Remove the latest Monthly Rollup (revert to the February version)
Use System File Checker (I checked the system image first using the DISM command)
Add "+miles_channels 7.1" to the startup options
Run the Windows Hardware and Devices Troubleshooter (I ran it from the command line)
Run the Audio Troubleshooter from the Get Help app (I added the Microsoft Store to LTSC and used the reinstall option)
Razer Game Booster
Does Apex only support stereo and mono now?
