When it gets disabled, Enable audio channel becomes unchecked. I have to go back in and check the box and click OK. The gain is set to 200% because the audio is too quiet normally. I haven't seen any issues with hiking it up to 200%. In troubleshooting, I've left it at 100% but it doesn't fix the issue of the audio channel disabling.
I have 5 cameras total. This is happening on 2 of them. Another 2 do not have audio channels, and the last one has been disabled. Does anyone know what could be causing this?
