Time stamping when audio begins to play

Is there a way of getting a timestamp for when you start playing audio similar to how you can get a timestamp for a Screen flip?

So far I read an audiofile in and load it using audioread and audioplayer. I want a way of noting the time that the player starts playing the file.

Any help is greatly appreciated!!!

As far as I know, getting the timestamp for a screen flip is something that would require the third-party Psychtoolbox, but if you know a MATLAB way, then I would be interested in seeing that.

audioplayer has a StartFcn callback that you could use now() or datetime() with to get a timestamp. However, I would be suspicious about the accuracy of that, since functions can take arbitrary time to execute.
