Been having a strange issue the past few weeks - when I start a DDO session, everything is working fine, but after maybe an hour or so of play, my voice chat stops working properly. Usually, I can still hear others, but can no longer be heard (name doesn't light up when pressing push-to-talk button, nothing). Relogging/restarting the game fixes the issue, so it's not a hardware issue (at least not a permanent one - could be something intermittent like overheating), nor a setting that got changed accidentally. Anyone have any suggestions what could be causing this, and what (other than relogging whenever it happens) might help to address it?
