Topic: SONAR playback routing to AN1/2

This regards an HDSPe AIO card with the 3.29 driver. I can't get audio to route from SONAR 8.5.3 to the
AN 1/2 channels of the HDSP mixer. The meter in SONAR is alive on playback, but the HDSP meter for
playback on AN 1/2 shows zip, and there is nothing audible on the AN 1/2 output channels. Routing
through any other playback channel works fine, and I get playback through AN 1/2 in other applications.
Any ideas?
