Help looping through mat files with sound function

I have several *.mat sound files (e.g., tunes_audio.mat) that I have load into my Matlab workspace using the following code:
s = what;
matfiles=s.mat;
for a=1:numel(matfiles)
load(char(matfiles(a)))
end
I would now like to play each of these files using the sound function. Simply typing sound(tunes_audio) works just fine. But I want to loop through all the loaded files and play them one at a time without having to type each name into the script. I have tried sound(char(matfiles{1}(1:end-4))) but I get an error message saying "Audio data must be real and floating point." Would somebody please help me loop through and read each loaded *.mat file?
Thank you in advance!

dinfo = dir('*.mat');
for K = 1 : length(dinfo)
thisfile = dinfo(K).name;
datastruct = load(thisfile);
fn = fieldnames(datastruct);
data = datastruct.(fn{1});
fprintf('now playing: %s\n', thisfile);
sound(data);
end

You probably need to specify a sampling frequency in the sound() call, but you have not given us any way to know what the appropriate frequency would be.
