Use audioread but only returns sample rate but no data

As the title says, I use audioread but only returns sample rate but no data. In fact, in my collegus' computer, they can get the whole data but it doesn't in mine. Mine is 2016a, theirs are 2015b. So, what is wrong? Could someone helps me? Thanks in advance!

After days of thinking, I now may know the reason why I failed to extract the data from aac files. It is because aac files can only read by Apple devices. And if we use MATLAB with Chinese, we may fail to read it. Therefore, two solutions are found. One, to download an MATLAB in English; two, to tuen the aac files into wav or other files that android devices can read. I tried the second one and successed at last.
