Why I got the message "WARNING: Cannot get normal audio data! "

The latest version Skype API become unstable, please restart the Skype to have the issue fixed.


If the issue still happen, please see the below solutions.



Solution 1.


Please upgrade your Evaer to the most recent version( and please enable the "Capturing audio stream does not use the Skype API" option as below image shows to have the issue fixed. 

Upgrade link is http://www.evaer.com/upgrade.htm 



If the issue still exist, please temporarily turn off your Anti-virus software, the Anti-virus may get a false positive detection on latest Evaer. Then restart Skype and Evaer to have a test.


Solution 2.


If you have checked the option "Capturing audio stream does not use the Skype API" as below image shows at your Evaer settings.

capture skype calls without Skype API

Please make sure your Evaer is the latest version, upgrade Evaer at http://www.evaer.com/upgrade.htm

Please record new call to have a try after you done the upgrade. If this message still pop up, you can uncheck the "Capturing audio stream does not use the Skype API" option to have the issue fixed.

And please make sure your Evaer change to "Ready" status before your place the Skype call.

Evaer video call recorder is Ready


If the above option NOT be checked, that means one of two things happen.


 1, Your computer firewall block Evaer to setup TCP connection for receiving audio data.

I would suggest you to open these ports (21387 and 21386) in the Windows firewall to fix the issue.

Open a port in Windows Firewall

Allow a program to communicate through Windows Firewall

 2, Your Skype may be lost connection.  Please check your internet connection. Notes: For this reason will not lead to such results(The recording may be at the wrong speed or the recorded file will be useless).


If you think that the detection message is wrong, you can disable the message at Evaer menu "Tools > Options" > "Advanced" tab > uncheck "Enable automatic error detection" option.
