If you manually turn on the analog generator on the AP, does the meter in the Sound control panel's Recording tab have green bars?

All Render tests are passing but all capture tests are failing with error below: AP no longer generating sine wave Error: 0x0, Error 0x00000000 Test signal not detected on channel 1. Base frequency 0.732422 Hz; expected 997-ish Hz We ensured all the connections between AP and SUT are proper. Has anyone else faced this issue? Regards, Surabhi
