I use OBS to stream our church services and Record the files. The Stream audio and video are perfect, but the audio on our recording is distorted and crackly. We use a program called Boxcast to broadcast our services using HDMI. To record, we save to our hard drive in MP4 format. I have tried saving to a flash drive and as a .mov file and it was the same results. I have updated all of our drivers, OBS, and last night did a complete reinstall and it didnt fix the problem. We have used OBS for a year and not had this problem until a few weeks ago. Any help you can give would help a lot!
