UE 5.4.3 Pixelstreaming audio streaming bad quality

In UE 5.4.3, when transferring the sound played in the editor with pixelstreaming, the sound is distorted and a distorted sound is playing in the browser. The same situation works correctly in 5.3.2. I think this is a bug and is caused by the editor.

You can try using https://www.streampixel.io/ . It works fine there.
