CC 4.16.3.4

My audio hardware is set to 48k sample rate. When I launch CC the display on one of my audio devices changes to 44.1, and I do not hear Jim and Clare. If I open Windows Sound Control Panel and select the output device CC is connected to, I can see under the advance properties tab that the sample rate has changed from 48k to 44.1k. Whey I manually change it back and restart CC I hear Jim and Clare correctly. If i try to enter Iracing without resetting the sample rate, the audio activity indicators shoot through the roof and the sim is unuseable.

I have specified that CC use 48k in the preferences for audio where appropriate: sample depth = 16, sample rate = 48000. I was using WAVE OUT as the output interface type, but just switched it the WASAPI. nAudio is being used for playback.

ANy thoughts on this one?
