snd('Play',...) needs output argument err defined

1
Hi,

this is a report of just a minor glitch:
the output argument err is not defined in the 'Play' branch of snd.m
(i.e., the part where Matlab's sound routine is called).

??? Output argument "err" (and maybe others) not assigned during call
to "/Applications/Psychtoolbox/PsychBasic/Snd.m (Snd)".

Maybe err should be initialized to a value other than 0 or 1 at the
beginning of the script, but I have no idea what that value should be
(err = -1?)

Test cases:
(1)
load handel
err = Snd('Play', y, Fs);

(2)
el = EyelinkInitDefaults;
err = Snd('Play', el.calibrationsuccesssound);

Best, Jochen
