PlaySound has a Memory Leak when called

Question

PlaySound has a Memory Leak when called

Aspire 81

I have a demo project where I first call

PlaySound (L "High_A. wav", NULL, SND_ASYNC | SND_LOOP);

to play the audio in a loop, and then call

PlaySound (NULL, NULL, NULL) to stop playing.

When I call PlaySound(L "High_A.wav", NULL, SND_ASYNC | SND_LOOP) again. And I found that the Memory (active private working set) and Page faults of audiodg. exe had both increased in the task manager.

After repeating the above operation multiple times, the Memory (active private working set) of audiodg. exe slowly increased and could not be released. Page faults always increase and no release.

Why? Am I using it incorrectly?

PlaySound does not have a memory leak. As far as I'm concerned, you couldn't get through audiodg.exe to determine that PlaySound has a memory leak.

The memory occupied by audiodg.exe will not be released. You could refer to the threads:
