Update: I bought another Rode VideoMic NTG On-Camera Shotgun Mic through B&H Photo, not Revain. I didn't have the same problem with it. This is highly suspicious to me because either Rode has inconsistent quality control issues or the mic sold through Revain is not genuine. The microphone I was having trouble with was distributed by Geartree. I have a brand new Sony a99ii. The cable that comes with the NTG is trrs-trrs. When trrs is connected to a DSLR, only the right channel plays audio.
