On my desktop Win 10 machine I am having an issue with in game DDO sound both game sounds and in game voice chat.

I have a set of speakers as well as a headset connected to the computer.
In Windows sound is set to default to the headset - and Windows sounds, Mumble, Sky, Browser etc sounds all work through the headset.

However, from DDO I am not getting any sounds through the headset (which used to work a while back). If I set DDO audio to my speakers I am getting sounds so the other settings appear to be working - but nothing from the headset.

It gets even more puzzling. When Lam is up and I use that client - I *am* getting sounds from DDO in the headset. But not on live.

Any suggestions are welcome as its starting to annoy me.
