类似于这个问题Basic sound error in Matlab (with no answer)，当我尝试播放声音（Matlab 2012a，Windows 7 64bit）时，使用sound、soundsc或audioplayer，我得到一个错误：
>> load chirp.mat;
>> soundsc(y,Fs)
Error using sound (line 60)
Too many input arguments.
Error in soundsc (line 48)
sound(varargin{:})
我怀疑这是设备驱动程序问题，但这只是猜测。Matlab 似乎看到了音频设备：
>> devinfo = audiodevinfo;
>> devinfo.output.Name
ans =
Primary Sound Driver (Windows DirectSound)
ans =
Speakers (High Definition Audio Device):1 (Windows DirectSound)
ans =
Speakers (High Definition Audio Device):2 (Windows DirectSound)
有任何想法吗？
