How to disable noise suppression when an application is using the microphone.

So I'm just gonna share the solution I've done after doing all the solutions here and still not working. Just uninstall the audio software and done. In my case it is the Realtek Audio Console in Acer, after I remove it everything is working properly now.

I realize this is a year after your post. I am very frustrated. My voice can be heard but not my guitar. This happens on Skype and Zoom. I have turned off noise suppression. Still has the problem. Nothing like this happened on Windows 10. Now that I have Windows 11...... It's driving me nuts. Did you find a solution?

Hi,

Thanks so much to all who have shared on this post.

It greatly helped me and my community (the piano sound had been suppressed on a Windows 11, HP Envy) .

I created a resource summarising the workarounds listed on this forum for my community - feel free to share if it's helpful.

Just to add to this horrible experience - I had the same problem on a new Dell latitude 5530 laptop, Windows 11, with Realtek audio. I had all the "Enhance audio" settings turned off, as above, and no additional audio software - I didn't have Dell Optimizer, or the Dolby one, or the Realtek console - nothing at all. And recording in audacity would record my voice, but not my guitar. The quick test is just to record your voice, and then clap a couple of times. Audacity would capture the voice, but not the claps.

I eventually solved it by *installing* Dell Optimizer for the first time, and then disabling all of the audio enhancements in Dell Optimizer. There is also a master enable/disable button at the top which I disabled for good measure. And then audacity recorded claps and my guitar as well.

Somehow, the echo cancellation (or whatever it is) was activated in an invisible way that wasn't possible to turn off without using something like Dell Optimizer. Is that a Windows 11 bug (ie, disabling the enhancements should disable whatever audio "correction" was happening, but it doesn't) that Dell Optimizer by chance fixes? Very unclear, but that has prevented me using this laptop for audio for its first year of life.

Thank you so much for the summary! I'm glad we finally got some solutions, because it was very frustrating to have such a major problem as soon as we got new computers with Windows 11. It was a problem that never should have happened in the first place. Both Microsoft and the computer manufacturers owe us an apology for making us go through this. And thanks for the credit!
