In DCS and DCS Open Beta, latest versions of both, in Caucasus & Syria, in A-10C II, A-10C, SU25T, T45 & TF-51D, a couple of audio channels aren't working. Specifically voice-overs including ATC and AWACS, and EWR alarms.
I can hear most other game noises, including switches, engine, environment, aircraft warning alarms etc.
This is multiplayer and single player, including missions and campaigns.
I have changed Audio options to various different outputs with no success, I've run the repair function and now I'm stuck.
