Thanks for your quick response Shon. I did unmute the audio but I still don't hear anything. Also not sure why I don't hear anything when connected to the grip so I decided to call Gopro and they guided me to troubleshooting and it ended up asking me to send them my stabilizer.
Here's what I did prior to having it replaced:
-Test recording with just the camera itself and audio worked fine
-Test recording with the drone while flying with all possible audio settings I could check and test each one(Unmute, Wind Only, Stereo, Auto) but no luck.
-Attached the stabilizer to the Grip and record, checked all possible audio settings as well but no luck
-Disconnect/Connect back the camera to the stabilizer and redo the first 4 process but still the same.
-Manually update the camera again, tried updating the grip but still the same
** I am so upset and called Gopro. It would take 2-3 weeks as they say for parts replacement
+++++++++Whole UNIT Replaced by Best BUY++++++
I just bought the drone last Friday night at Best Buy so I went there and they replaced the whole unit. I test the replacement drone, the camera, grip and they all have audio recordings now.
