I have a Canon Rebel t7i. I recently purchased a wireless lavalier microphone. Whenever I connect it to my camera and use it for a video, the video's audio contains a loud whine that only cuts out when someone is speaking into the microphone. The audio sounds great when I use the microphone in a video taken by a phone or a laptop, so I don't think the microphone is defective. Any ideas on how to get it to work well with my camera?
