Question How do I get mic input level to STICK?

[Paul Anderegg]

Had the same issue on Windows 10. I will set the audio level for the mic input, which is connected to a police scanner for a live stream, and no matter what I manually select, it will AGC itself up and ends up overmodulating the sound. Audio enhancements are OFF, and there is no AGC checkbox or feature I can find. It is driving me nuts.

AGC being Automatic Gain Control - correct?

Have you been able to try any other mics and/or audio related connections? I did note "no matter what I manually select" but not sure how far you could really go with selection options. No harm in asking....

Not sure of your overall audio connections etc. but look into loudness equalization with respect to any and all audio related hardware and software configurations.

You can easily find other similar links.

The next thing to check is TRS (Tip, Ring, Sleeve).

If there is some mismatch, for whatever reasons, then any normal or expected controls may not work.

Maybe I'm missing something here; are you connecting the output from the police scanner to your computer? Perhaps a better way to connect this would be to use the Line Input on the computer and not the mic input. If you could tell us the make and model of the police scanner and how it outputs its signal maybe we could find a better way to connect it to the computer.

The scanner is a Whistler, connected frok the speaker out to the mic input. The streaming PC is one of those tiny book size micro Lenovi PC's, so it only has mic input, and 44/48Khz as audio options. Level 50 for Windows 11 is 0db, and other than level and sampling rate, only the enhancement toggle exists.

I run the input through Equalizer APO to prep it and remove specific audio hums, but even without that program, the level thing still happens. Oddly enough on Windows 10, active EAPO would cause the mic level to not auto adjust.

As for loudness equalization, I have the levels matched for exceptionally clean passthrough at that 0db level, I just want it to not literally slide up in volume as I stare at the damn settings menu. It's like it's taunting me. Loudness equalization would harm the audio quality a lot. I was hoping someone maybe knew a registry trick to keep it at a specific level.
