Screen Recorder microphone sound not recorded

[Ephant]

My Windows 10 IceCream Screen Recorder app was not able to record via microphone the sound during a particular screen video capture even if the microphone is turned on (but only 5%). In other instances, the microphone sound is available and also in tests afterwards. I was able to record microphone even if it's only 5%. I don't know what occured in that particular recording. I got the following result in Mediainfo. Can I recover the sound? I tried opening the *.webm file in Audacity but it can't recognize it. How do I recover the sound, or amplify it? Can any of the following information give one idea whether it is recorded? Audio

Perhaps the microphone cable has a problem; as a test, try recording your voice while wiggling the mic cable and connectors..

A Google search turned up some information:
https://www.google.com/search?&q=playback+for+a_vorbis+encoded

Near the top of the results was this:

Since February 2013, Xiph.Org has stated that the use of Vorbis should be deprecated in favor of the Opus codec, which is also a Xiph.Org Foundation project and also free and open-source.

Good Luck!

It's from a built in mic in the laptop. I think the problem is the volume is zero for the mic.

Is there a way to still recover the sound? There is a saying information can never be lost. So how do you recover a sound that is not recorded in a file at all?

Wellll ... yea.
The process though is rather impractical.

a) Sound - pressure variations of the air
b) Get a working recorder far enough away fast enough that the sound has not yet arrived.
c) Considering that the Earth is surrounded by a vacuum, you are limited somewhere on the Earth
d) Get to the opposite point on the earth (the antipodes), about 12,000 miles away
e) While traveling faster than the sound, you will also have to develop a method to detect and record the darn near non-existent sound you want.

You have 16.66 hours from the time the sound occured.

Oh well, time to cry in your beer.
