This means that some code tried to open device named "front", and that there is no such definition for your hardware.

Thanks, Clemens,

Here's my code that opens the device:

int driverID = ::ao_default_driver_id(); ao_sample_format format = { 0 }; format.bits = 16; format.channels = inNumChannels; format.rate = inRate; format.byte_format = AO_FMT_LITTLE; mDevice = ::ao_open_live(driverID, &format, NULL); if (mDevice == NULL) { LogDebug("Error opening output device"); }

I'm not sure where the change in default device would come from.
