I am having trouble playing sound with MATLAB R2015a on Linux/XUbuntu 15.04. When executing

load handel;
sound(y,Fs);

for instance, the terminal throws the errors shown in the attachement. A colleague of mine is facing the same issues on an XUbuntu machine.

I use an external class complient USB sound interface (Lexicon Alpha) which is the system's default sound device.

What to do?

Try increasing the value of the latency that the audio device runs at. To do this, execute the following steps :

Navigate to $MATLABROOT/toolbox/matlab/audiovideo/@audioplayer/ and open audioplayer.m for editing.
Increase the value of DesiredLatency (on line 147) to something like 0.1
Save the file and retry playing the audio files from MATLAB
