No sound from G5 Pro PoE on RTSP stream

Hello. I have 2 G5 Pro PoE recording to NAS with RTSP protocol. Often my RTSP recording do not contain audio. To bring it back I need to go to the Aqara app, open the camera live view and tap the speaker icon that enables audio.
I need to mention it seems that this also applies when watching the stream from Apple Home.

Hello, welcome to the forum. I had this problem once, I switched to this setting. It helped me, although I haven’t researched this problem further. Try it.
