How to stop streaming audio2face manually from unreal?

Could someone help me with a problem? i want to stop the playback of audio in streaming clicking on EndPlay in unreal,but when i press the button the animation still continues but without sound.

Hi did u solve it? i encountered the same question. thanks for reply

yes at the end i solved using a variable isStreamingOFF,that became true when clicked on EndPlay. After in the cicle for of streaming of chuncks,the thread check the variable and if true it break and go to
writer->WritesDone(); and
Status status = writer->Finish();
