Description:
Since the 1.9 update, Arma Reforger has no sound at all in more than half of my launches. Every in-game sound is missing. Meanwhile Windows and every other application keep playing sound normally on the same output device. Windows sound settings and the Volume Mixer are set up correctly.
Restarting the PC sometimes fixes it, but not reliably, and I can’t find a pattern. I never had this before 1.9, on the same hardware and drivers.
Steps to reproduce:
Start Arma Reforger from Steam.
Reach the main menu or join any session.
In about half of launches, there is no game audio at all.
Restarting the game or the PC sometimes brings sound back, unpredictably.
Expected behaviour:
Game audio plays every launch on the Windows default output device.
Already tried (no effect):
Moved all local config/profile files out of OneDrive sync
Turned off Windows Game Mode
Switched output devices: USB DAC [model] (Windows USB Audio 2.0 class driver) and Bluetooth headphones [model] (A2DP). It happens on both, so it isn’t tied to one device or driver.
Confirmed Windows default output and Volume Mixer settings are correct
