Error Opening Recording Device

This is my first time posting and I’m not even sure if I am in the right place but I need help before I rip all my hair out! I record a lot of news clips, 911 calls, etc for my podcast and all of a sudden I am getting the attached error. I did not change any settings or do anything different, it just started happening out of nowhere. I searched all the help forums, have done what is suggested in those forums, and nothing is working. I am on the verge of tears and need to get this episode out. Any help would be greatly appreciated!

Try Transport > Rescan Audio Devices

What are your Audio Setup specs?

If you are using WASAPI are you using the maximum number of channels (usualyy 2).

Have you tried switching to MME (or DirectSound) ?

Did you reboot ?

Do you have permission to use the microphone?

Somehow my channels got switched to 1. Switched it to 2 and it worked! THANK YOU SO MUCH!!!
