在 MATLAB Online 中打开

Device used: Macbook Pro 2018 10.14.3

Matlab version: R2018b 9.5.0.944444

I am encoutering an error when using the sound/soundsc functions in Matlab, after plugging in (or unplugging) headphones. Matlab properly plays sound prior to plugging/unplugging them, but will throw the following error after, even if I began with them unplugged, and later plug them back in. Restarting Matlab fixes the issue with headphones in OR out, until plugging/unplugging headphones again.

My code:

fsamp = 11025;
dt = 1/fsamp;
dur = 1.8;
tt = 0:dt:dur;
psi = 2*pi*(500*tt.*tt + 200*tt);
xx = real(7.7*exp(1j*psi));
soundsc(xx,fsamp);

Error:

Error using sound (line 76)
Device Error: Internal Device Error
Error in soundsc (line 55)
sound(varargin{:});

Debugging the sound function shows me that the exception is thrown from line 74 in sound:

play(playerObj(end));

But I am unable to figure it out beyond this. I have checked the audioplayer and audioDeviceWriter objects, and they properly update when the headphones are plugged/unplugged. I'm not sure how related they are to this issue, and am wondering if this could be a Mac issue?

Any help or direction is appreciated,

also battling with this! MacOS Monterey 12.4 :(

Why is this issue still present in 2022a after 4 years? MacOS Ventura 13.0.1

The only workaround I have so far is to get the first device that's not bugged via audiodevinfo(0, 44100, 24, 1)

I don't know if others are still facing this issue. Previously I was plagued by it all the time and the only recourse was to quit and restart Matlab. More recently (version R2022a, MacOS 12.4), I no longer seem to get the error, but Matlab still does not recognize when I plug in headphones. In case this is happening to anyone else, I am now able to solve this problem by typing audiodevreset
