Most likely the driver allows only a single pin instance. When an
application (SONAR) creates a pin instance, Windows audio subsystem is
unable to create another instance for its needs. All MME (WaveOut) and
DirectSound software buffers playback from all applications go via Windows
audio stack and
require only a single pin instance because of software
mixing/conversion. Only KS applications can compete with Windows audio
stack, acquiring pin instances directly.

Eugene
