Hello! I also have sound issues. DCS (both release and beta) refuses to play sound through my speakers but does play sound through my headphones.
I tried disconnecting my headphones and leaving the speakers as the only output device in Windows, it didn't help.
I also looked into the 48/44 kHz issue. I found some errors in DCS log on the default 48kHz that disappeared when I switched to 44kHz, but I still had no sound. However after switching back to 48kHz, the errors didn't return. Still no sound.
Logs are attached, the "48k-first" is the one with faults. In all these, I just opened the game and the audio settings. I switched between the default device and the speakers in the 48k-first. I also tried that later without faults in the log. I also tested the sound in game to confirm it isn't just the music, that's not in the logs. All the logs are with headphones disconnected.
I can test other scenarios if required, I'll be checking the thread. dcs-48k-first.txt dcs-44k.txt dcs-48k.txt
