Pixel Streaming does not stream audio at all even when running streaming in the editor.

UE 5.4.

Hello. What could be the reason for Pixel Streaming not transmitting audio at all? Neither when running a packed game, nor when running streaming in the editor. Standard Games/Blank project, one sound on the stage (song). I run streaming through the PixelStreaming panel in the editor. The client is the official PixelStreamingInfrastructure-UE5.5-4.1.1\Frontend\implementations\react. The client connects, receives video, but not audio (the video element does not have any audio tracks).

Hi there!

One thing to note about Pixel Streaming audio is that all audio is captured from the engine’s default audio submix. This means if audio is played through any other mechanism that does not go through the default submix it will not be streamed.

If you’re using a unique plugin or custom audio solution, you might be bypassing the default audio submix and losing audio via stream.
