Respectfully, you need to update you recommend list. "EVERY camera that is in my recommended list in this thread that has a speaker and I use it to play a video file:"
I selected the first one on the list and bought and this is what they shipped. I clicked through to the list as I didn't see the ones listed after suited my needs.
Also, to bigredfish, I bought a Dahua and it said two way talk on the box and when you clicked the microphone on the Dahua app, it said, "function not available". I will keep trying...never give up.
I do think it odd that when I send sound specifically selecting the camera as audio output, you would think no sound would occur. But, it bounce to the PC speaker when I specifically specify the camera....hum...you would think it just a dumb stream to the RCA jack, not bounce to the PC.
If the box said "speaker" you bought a different camera than you said you did earlier. Or you got a repackaged box
lets see the box
