Video camera recording without sound - G4 Q&A, Help & Troubleshooting

For some reason my phone doesn't record the sound when shooting videos. Also tried with 3rd party app but no sound being recorded. Not sure if it's a setting I accidentally enabled. Any idea how to get the sound back?

[Q] No audio recorded in video record apps (calls, audio record is ok) 4.2.1

Hi all,
I noticed a couple of weeks ago that the standard 'camera' app started to record videos with no sound..
There's just quiet white background noise in videos (as if mic is very low level)..
I've tried the stock ''camera app', and also 'camera mx' app - same thing.
Quite strange as mic itself is ok - people can hear me on calls, and audio recording apps ('Hi Q MP3 Rec') work ok too.
Any ideas?
I'm on a stock rom, the phone isn't even rooted.
Thanks!

Video recording loud hiss

I just noticed that there is a loud hiss sound in the videos I record. Has anybody else experienced this? I tried recording in different resolutions but it does not make a difference.
Edit: I just recorded a video using Instagram and the hiss sound is gone. It has to be the Lg camera app that's producing the background noise.

Video Recording hiss

When I record a video with or without high res audio, I get a hiss which is the unwanted white noise kind of audio. Anyone else get that? If so is there someway to record without that hissing sound or maybe another video recording app that fixes it or something.
Do you hear the noise when you playback the recorded video through phone itself or PC?

Both actually. I have a feeling it's just the phone's audio recording quality. Although it is quite good, I feel it lacks noise cancellation.

Anyway to remove noise suppression in video recordings?

There's noticable noise suppression in video recordings which really affect the audio quality. As much as I like it on phone calls, I don't always record voices when shooting video. The noise suppression really destroys the sound of the environment. Anyone know a way to disable it?

Only way which I think is shooting in manual mode and disable wind filter, and optionally use HiFi audio recording which will enable recording sound track in lpcm.
But I very much doubt that tiny mics of G7 are capable to correctly picking ambient audio of 10-20 dB volume levels. They're too tiny, you should rely on external USB microphone with much higher sensitivity

¿Does anybody knows how to disable the audio noise reduction filter?

It's nice to filter all but human voice sometimes, but, there are times when I want to record music, ambient sound, etc. and the filter just crushes to silence all sound below some dB level. That means all fine details in recordings that are not that loud are just lost in the final recording due to the aggressive filtering.
It appears to be enabled system-wide: Video recording, Voice Recording (Even with the built-in LG audio recorder app), Whatsapp voice notes, etc.
The only way I have achieved to bypass it was with the "RecForge II Pro" app, with the next settings:
Audio Record: 44kHz. Stereo(Native) 128kbps
Source: Front Microphone.
Disable AGC: Not marked. (If marked: the recording is in REAL stereo, but filtered as mentioned above, so is just like the recordings from the LG app).
Even with this, the recording is just "Duplicating" the bottom mic signal to both channels (R, L). I cannot manage to get real stereo without that filtering.
It bothers me sometimes when recording videos os stereo audio recordings, because it has a pretty good camera and good quality built-in mics, but it gets compromised with that audio filtering issue. Let me know if you know about some solution for this problem.
Thanks for your time.
Use HD voice recorder app by LG. Or use manual video from camera settings, enable Hi-fi audio and click on Hi-fi when you shoot video.
