Symptom
Error "Exception from HRESULT: 0x80040DFA" is displayed
Cause
Getting this error in an RDS session when starting Online Speech Recognition is caused by newer versions of Philips extensions, starting with 4.4.441.x. The featured auto detection algorithm seems to put too much data at once on the RDP protocol.
Resolution
Please install Philips SDK Upgrade Patch Version 4.7.470.08
