V3 “Record sound” static…

I recently installed a wyze sd card into my V3 cam and set it to record continuous. When I replay the video or do a live view the sound has a ton of static. It is basically useless to me. Any suggestions? I am running the rtsp firmware if that makes a difference. Thanks for any help.

I have static on live stream and playback on the cams that are running the rtsp firmware.
The one using the released firmware is quiet.

THANK YOU for your reply. That confirms that I don’t have bad cameras. Would you mind telling me what RTSP firmware version you are using? Curious if it is the same as mine.

Yes. That’s the version I have. I think that it is the only version there is for the v3 camera
