The number of speakers the device/drivers supports... 2 means that there is no support for speaker assignment - this will always be the case with non-WDM drivers in Windows.
It's also possible that it could mistakenly be 2 with some devices/drivers, when the device in fact supports more speakers.
In that case the BASS_DEVICE_SPEAKERS or BASS_DEVICE_CPSPEAKERS flag can be used in the BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) call to force the enabling of speaker assignment.
