So tonight I decided to monkey a little bit with the sound options, while I was on climb out.
I had my Speaker and Headphones set to Digital Realtek Sound before, and the "Use windows configuration" on the top pull down.
I changed the top pulldown to "Headphones" because I'm not using speakers.
Well I lost sound completely. Didn't matter what I changed them back to. I exited the game, still nothing, rebooted, finally got em back after rebooting a half dozen times.
I also noticed while trying to fix my sound, I went into offline mode, and couldn't be in offline mode for more than about 30seconds. I was in an M8 and a Panzer and testing the sounds by firing the main guns....and just crashed after about 30 seconds.
Not sure if this is the right spot for this, but thought I'd mention it.
