title_body: Does the LaForge V3 Fat Shark Receiver receive audio from VTX? I installed the Mach 3 VTX that has a built-in mic for audio that is transmitting to the LaForge v3 receiver in my fatshark dominator v3 goggles. Video works great and Smartaudio is also working. I hear nothing but static from my earbud. 
  
  I tested the earbud and it worked on my phone. I also made sure I am plugging the earbud into the headphone jack next to the HDMI port on the goggles. I'm pretty sure I have everything set up correctly but before I try ordering another VTX and swapping parts out I want to make sure that my setup is compatible with Audio.
upvoted_answer: The V4 has audio, but I can't find any information about whether or not the V3 has it. I did however see that a manual mentions a VTX audio option in the menu. But since it doesn't say which version, the easiest thing to do would be to see if you can find that option and make sure to turn it on.
