I removed my BCD536HP dongle and want to record using straight audio cable. I changed my input sound device to Primary Sound Capture Device but I get the Proscan error message "Unable to open source client...….Undefined external Error". The cable itself does not appear to be the problem because I can hear the scanner audio on my computer speakers. I've tried using a BCD996T and I still get same message. I've tried changing to MIcrophone input, but still with same results. I've tried both the back and front input jacks and still the same message. Any thoughts? TIA.
