I'm executing this Code:
filename = ['EHG_HRIR_in.wav'];
disp(filename);
audiowrite(filename, combined_signal(:,side), Fs);
And the error message Matlab is throwing:
Error using message
In 'MATLAB:audiovideo:audiowrite:invalidFileExtension', parameter {1} must be a real scalar.
Error in audiowrite>validateExtension (line 379)
error(message('MATLAB:audiovideo:audiowrite:invalidFileExtension',...
Error in audiowrite>validateFilename (line 394)
validateExtension(filepath.Extension,filename)
Error in audiowrite (line 165)
[props.filename, fileExisted] = validateFilename( props.filename );
I'm very happy, if anyone could tell me what is going on.

The error message is wrong:
'MATLAB:audiovideo:audiowrite:invalidFileExtension', parameter {1} must be a real scalar.
The function get.WriteableFileTypes in PluginManager.m returns an empty array which indicates a missing C++ library.
@MathWorks Support Team An appropriate error message like "no writable file type found, check system's C++ sound libraries" would help a lot.
I'm not an expert but I could solve the problem by installing the necessary libraries e.g. by installing the Synthesis ToolKit in C++ (STK)
sudo apt-get install stk
'clear all' the console
Now it should work.
