problem generating audio file from "From File" block in simulink

hi, here is what in my m-file:
[sound,fs] = wavread('admirer.wav');
r = sound';
save ('wavplay.mat','r');
the problem is after adding this to "From File" block in simulink, this error appears:
"Simulink does not support loading the input data in file 'wavplay.mat'. For data saved using MAT file versions prior to 7.3, Simulink can only load two-dimensional arrays consisting of one-dimensional, double, noncomplex samples. To load data of any other type, complexity or dimension, use a timeseries object and save the file using MAT file version 7.3 or later. For example, use: 'save file_name -v7.3 timeseries_object'."
as i wanted to take the output of this block to "PWM" block of Arduino target hardware.
thank you in advance!

To load workspace data using From workspace block, you data should be in time series format (A time series object OR array with time OR structure with time).
To understand, take a Workspace block in model and save some data using it into workspace. Analyse the saved data.
