LG P920 — Camcorder's audio quality totally messed up without reason - LG Optimus 3D

Hello there fellas!
First of all, I'm not that super active member here on the boards, but I've been lurking around for a while now, this forum is a fantastic resource for smartphone users for sure! Well, the reason I am opening this thread is that I have a P920 for about 6 months now, and I ran into an issue and can't deal with it, I thought I'd ask the pros here what could be the solution for that.
The issue is that the phone's camcorder recording insanely rubbish audio while shooting a video. I like this phone because it's audio quality on the recordings were great, I've made several shots with it. But a few days ago something went wrong, and I just cannot understand what is going on.
No matter if I record a video in 720, 1080p, even in lower resolutions - the picture is just fine, but the audio is not that it used to be. It's not crystal clear, it's crackling now, crunching, and I can't even hear my own voice on the footages - making the camcorder feautre of this great device useless.
The thing is, I decided to upgrade the software on it, I've been using Froyo for a long time but I was missing the ICS features so I wanted to try and ended up with OneClickRoot and a rooted phone with CWM on it. So far, so good. No problems after the root for a few days. Than, suddenly I realized that the audio quality on the video footages I make are instanely useless - crackling. Every time. No matter what I do, it's just not that quality as it used to be.
I've followed a tutorial on how to upgrade my P920 to ICS hoping that it will solve this issue. Well, the update went okay, now I have ICS, everything works just fine except the camcorder. Same issue, crackling sound.
Funny thing is, during a phone call the audio quality is fine, using the sound recorder the audio quality is crystal clear so I am 100% sure that it's not a hardware issue.
I'll upload an example video file tomorrow here to this thread about this issue, unfortunately I can't do that right now. I can't understand what is going on, even an OS upgrade were unable to solve this problem. Again, the microphone is working fine.
Looking forward to hearing your thoughts fellas, I appreciate it a lot.
Have a great day!

Have you checked if the mic hole is plugged with dirt or lint or something?
I don't have the cracking, but when I take video of loud live music (usually in a small club) the sound is pretty crummy. My buddy has another brand of Android phone and he has the same issue. It's just really loud in there...
Anyway, I have wondered if there is some sort of pocket-sized external mic. for recording better sound. I'd like to hear about it if anyone knows...
Sent from my Oldschool Hardcore LG P925 with XBSA vR3D ROM and Backside Boneless FTW

What I did now is upgraded to ICS v28b using following this tutorial.
Now I am on the "stock" ICS - without the XBSA mod. Everything is working fine, except the audio quality on my videos.
I have recorded a sample video file at my backyard. Nothing fancy, holding the phone in my hands, please download the sample and check the audio quality. The video resolution is 720p, but the audio... It's horrible.
Download video sample here.
At the very same spot, I've recorded a sample audio file using the default android voice recorder, holding the phone in my hand. The audio qualiy is crystal clear.
Download audio sample here.
I don't get it guys. This issue started on Froyo, and than I upgraded to ICS (for the first time not sure which one) and upgraded to ICS v28b this time. I flashed the baseband to a different one as well (however I'm pretty sure it has nothing to with it) but still.
Basically I've changed the complete software "backend" on my phone and the audio quality still awful on video recordings. Please compare it with your videos, you will notice the difference.
Anyways, apart from that issue everything is just working fine, even the 3D features. Please shoot your ideas on how to fix this, because it's ruined the HD video recording feature of this fantastic handset. Thank you.
PS.: forgot to mention, I tried the XBSA ROM as well, and when I was on it, the audio quality on the videos were MUCH worse. Nearly unable to hear my own voice. This is the main reason I downgraded back to stock ICS using my nandroid backup, now it's somehow better (the current video file you can download here), but still not what it used to be.

I can get The jb camera, in The camcorder options we can select the input method its The one.

Umm, excuse me, I don't really understand what you trying to say here. Could you please explain? TY

Anyone with some idea? This bug still exists, and I have no idea how to solve it. Quite annoying
Is there a seconday microphone in the handset maybe dedicated to the camcorder!? Probably...

You can select the method input mic or videocam.

There's no option for that in video camera settings. Only "ON" and "MUTE" that's it.

Sound tweak to up volume?

Hi,
Does anyone know a way to tweak a system file so that Inspire's volume is higher?
I personally find its stock volume rather low, and I want to increase it.
I downloaded Zedge. It is a free app with nice louder ringtones.
Hope this helps!
I'm wanting to up the volume system-wide. But, thanks for the info anyway
Yea, I tested a movie and sling player last night. The media volume was all the way up and it was quite.
I went from iPhone 4 (nice and louad) to Atrix 4g (nice and loud) to Inspire 4g (too quiet).
I am loving the Inspire but the sound volume and battery life are definitely the 2 big downsides of it. Still a winner over the Atrix any day though.
I personally don't have issues with the battery. I've removed all extra stuff. Even before removing them, I was happy with its battery.
It can't be that hard to change the system volume. It's done in every smartphone and OS before. Hopefully, some developer notices this thread and help us out.

I'm half deaf. Need a louder phone please.
same here, the phone volume is too low. Maybe if can acces service codes? I did it on my previous Samsung phone.
Hi, all.
So, I've been doing some digging around, and looks like there are 2 possibilities.
One is to modify the system files manually (which would be very complicated), but I personally prefer this method rather than having to install extra stuff. However, this method is not available to us unless some very smart person shares the method with us.
Two, which seems to be the only viable option at the moment, is DSP Manager. As far as I understand, it used to be available through ROM Manager, but it is no longer there. I saw a thread that said the author was not releasing it anymore because most MOD developers were now including it in their ROMs from the beginning.
So, if we can find a way to install DSP Manager, we may be able to tweak the max speaker volume. But, that's as far as I could find. I'd need someone smarter to look into this.
Hi,
An update and a new idea.
First, DSP Manager doesn't work on Inspire 4G, so don't bother.
Second,
Here's a new idea I have about the low volume sound fix. I just read a comment from HTC employee who said, "The front speaker is for phone calls and the rear speaker is for everything else."
In other words, if we can find a way to keep the front speaker enabled all the time, we should be able to get more sound. I don't know much about what kind of coding is involved in routing sounds from each speaker, but I wonder if this would be an easier hack than trying to increase the entire system volume, which may still feel low volume for as long as we can't get any sound out of the front speaker.
Maybe someone smart can add to this possibility?
#1! I like to use voice recordings as scheduled reminders, and the playback volume out of the rear speaker is way too low.
I did notice the low volume on a movie i downloaded but you never can tell with those sorts of things. Overall the sounds is incredible even through the speakers with (SRS) and dolby mobile.
Could use something to ++output level.
Id like to see an app to change audio volume levels while recording video.
(ive only had the phone a couple days i returned my samsung Cap upgrade for the 4g, forgive me if there is such an app out there)
How often do you go to watch an awesome looking concert video and the sound is trash? It would make for some beautiful recordings i think. I have yet to test this one, but the Captivate could not record decent sound at all in loud environment.
I personally have come to believe that it is really not that the "volume" is low but rather a "wrong" speaker is being used. I mean, if the main speaker is on the back facing away from us, of course we don't hear much sound. If you flip the phone while playing music or video, you'll notice that the sound is actually loud enough. So, if we can enable the front speaker for normal use, I really think that it'll be just fine.
about every HTC phone has a quiet speaker. but cyanogen typically always includes the audio boost add-on. so i'd just wait for cyanogen 7 to include it, and your troubles will be solved.
well, even if the volume is boosted, as long as the sound is coming out of the rear speaker, if you place your phone on its back on a table or something, the sound will still suffer. It makes more sense to find a way to enable the front speaker.
Most of all phone have a rear facing speaker. But some phone are loud and some are not..

No, they don't lol. (you may be right if you are talking about specific brand or series, but certainly not "most of all phones").
I just came across something that may be relevant to the audio routing, but I'm not smart enough to figure them out. If anybody wants to take a look at it, it would be great:
http://developer.android.com/reference/android/media/AudioManager.html
There are several lines there that talk about Routing.

This may sound ridiculous but works!
Hi, all.
I just came up with a very simple workaround for "only when you are watching a video or something."
Now, you're gonna probably laugh, but trust me. It really works.
Just play any video, and hold your phone as if you are scooping water. The key is the left hand. When you cup your left hand around the rear speaker, it creates a echoing chamber that redirect all sound toward you. You'll be able to hear the sound much better.

Sound clipping in video after OTA 2.3.4 update?

Just spent the past 2 days taking a bunch of videos of family and stuff. I noticed the sound seems to be getting clipped and distorted. First I thought it was just the speaker on my phone, but now that I've transferred videos over to PC I can confirm the microphone clipping is pretty bad, and its not like there is shouting or anything.
This is with the OTA update on stock, 2.3.4 on TMOUS. Also using the new .MP4 format.
I don't think I noticed this with the original 2.3.3.
Anyone have any new videos since the OTA update and can confirm or deny sound clipping now in videos?
Thanks
There's always been clipping when recording video in stereo. It really sucks cause it takes away that great feature.

Audio is crappy for me on the stock camera. What I've been playing with recently is LGcamera and SO far, that has done everything I need! Doesn't have issues with the audio either (at least for me!) so it's porbably just a software problem. Hope this helps!

Awesome video sound improvement with MIUI

Hi all,
I'm making this thread just to let everyone know, that I discovered a DRAMATIC sound improvement when recording video on MIUI 1.9.30, which is my current rom.
I've done a lot of videos of myself playing the cello lately. Until now I've been on VoidU rom and the sound of the videos was very bad. It seemed clear that the internal microphone of the Desire S is not capable of recording the loud sound of a cello being about 2 meters away from it. The result was a crackling and strongly distorted sound.
It was a very pleasant surprise to hear my today's recordings, as the sound is incomparably better then it was before. It's actually good enough for publishing on youtube. I would never imagine that this could be possible just changing software.
(Didn't test it with other roms yet.) Thanx SuperKid!

Good to hear , Will some time try MIUI,
Till then m good with Runny1.5

Any idea what exactly the changes were? were they in ROM base or in the Kernel? and more importantly can they be moved into a Sense ROM! like VoidU!!!
Yea, thanks for posing these questions for me.
Well I don't know if this is ROM or kernel. And it might be a little tricky to test, since the kernels of VoidU and MIUI aren't interchangeable, right?
What I can do is try MIUI with TIAMAT in the same conditions.
As to what happened with the sound exactly, my impression is that the MIUI ROM might somehow guard the recording process so it does not get overexcited. It sounds like it is cutting off the excess sound input and maybe even compressing it, so it fits the possibilities of the recording device.
I thing this is often used in pro. sound recording, and the device (or software) is called compressor. You can set a loudness limit and the device takes everything that exceeds that limit and makes it quieter.

Try to post some bits of the vids later so you can see the difference.

I don't know if anyone tried this, but recording a video while having your earphones plugged into your Desire S improves the audio quality as well.
Too bad there isn't any news on increasing FPS, or is there?

Video recording sound distortion

Hi,
Ive had my Sensation for a good while now and despite upgrading to new current roms the sound is still horribly distorted when recording video.
Has this been fixed yet and if not is it ever going to be fixed?
By the way, I have tried disabling stereo etc and it makes no real difference, its still terrible.
Thanks
Nat.
I have the same problem :/ its horrible for concerts

What rom are you on? I believe Sense 3.0 has that issue. You can use the beta 3.5 roms if you wish (but the battery sucks on that) OR use what I like which is: ICS! The recording "clipping" noises is gone (at least for me it is)
same here, surprisingly though, audio from rezound's video recording turned out really good (minus the occasional scratch/pop sounds..)
Hardware issue?
Do you have a case? I noticed the same thing and then it came to me.
Sensation actually has two microphones (for stereo recording) so when you use a case most of them dont have appropriate holes so only recording source is the mic on the bottom. Sucks I know but its better then a naked phone

Microphone broken?

Hey,
i have a huge problem with my microphone. I got my u11 yesterday, I recorded a voice message via WhatsApp and I noticed that the quality is very miserable. I assume that a microphone must be damaged, but before I complain I wanted to make sure that this is not normal. In Videos the sound quality is alright (first example) but in voice messages the quality is very bad (second example)
I had to add a few blanks
good:

Have you tried recording a message in the stock recorder app? If it is fine then it sounds like WhatsApp is the problem.
It's not a problem of whatsapp. Because the problem also occurs with other apps.. i downloaded several voice recorder apps and always the same bad quality. But with the stock recorder app the quality is good.

So it sounds like the problem exists in 3rd party apps which probably haven't been updated to work properly with the hardware of the device. Doesn't seem like a hardware defect to me if you can get good audio recording in any app.
My WhatsApp sounds fine so yeah might be your mic...call someone and see
Same problem on mine
I have just bought an HTC u11 in taiwan and I have the same problem. I ran the audio diagnostics (See HTC.com support for instructions) and the Microphone #3 has a very low level with some electrical noise, so it is clearly a hardware problem.
The phone is 2 weeks old... I am very disapointed and ask HTC to replace it but they don't seem cooperative, they want to open it and fix it, which is obviously not great. Haing a brand new phone open for repair is not good.
Not Good HTC...

If you're within your return window, just return it. Buy another u11 or find a different device.
I have the same problem in microphone 3. Interesting enough, It is not completly useless and seems to get better from time to time. I wonder if there is a problem with the water isolation. The main problem is to talk while in loudspeaker, people cant hear me well. I wonder if I can divert the microphone while in loudspeaker so that the phone uses microphone 1, 2 or 4. Then my problem would be solved. Anyhow, if some functionality exist in the microphone, shouldnt we be able to increase gain?
There is something up with the microphones... Works fine in stock apps including phone and camera but fails HTC diagnostics and third party apps - the HTC diagnostic app doesn't even pull anything from any of them including the headset. I wonder if it's a kernel issue.
I have absolutely great news. I have discovered my problem at least. I happened to discover that the glass protection was covering microphone 3. The glass was badly cut and when I took the protection off everything was alright again. Maybe same problem jterpreau? please check.

Yeah, I had the exact same fault and it was the screen protector covering the mic.
Have removed it now and it's all good!
Yeah, i fixed it!!!
so mic #3 has issues, but i noticed that the protecting glass is the problem, because mic #3 is right above the screen and if you use inappropriate screen protector, it will lead to this. remove the screen protector and test it
i have issue using Instagram video snaps, the sound is awful and not clear! all microphones are NOT covered!
same goes for whatsapp videos!
however using the stock camera app, all works well!
PLEASE HELP!
Microphone broken? - U11 mic3
Same problem, initially worked for all audio, but after phone got briefly rained on, voice recorder does not work, and I have no voice output in calls. Video records audio (different mics). If I try to record on voice recorder it briefly registers one initial peak then nothing, playback produces one brief click at the start, which can be felt through the back (midway down, to the left) as well as heard. Earphones still work, although HTC's adaptor won't work if I plug the audio lead from the stereo into it. No wireless charging is a shame, can't cv charge when you're using the USB C socket for audio. I've been loyal to htc for a while, this phone is a disaster, for more reasons than I've mentioned, and far too fragile. I reckon it's hexed or coated in marching nanobots, you can't put it down anywhere without it sliding off - it often waits 5 or 10 mins before doing this, and requires no disturbance, vibration, notifications or passing traffic to assist it. My first u11 broke when it slid out of its case whilst in call, something it was quite adept at. Sadly it is the only HTC offered by my carrier as an upgrade from the m9 . I'm not saying the HTC one was without the odd issue, but I found them to be durable and robust, sensitive and responsive,and intuitive to use. There apoear to be lots of issues appearing with poor integration with 3rd party apps & hardware. Swype is barely useable, and glitchy. Very very disappointed. Looks nice, feels good. Insufficient design & dev. Doomrd. How fast did you break or brick yours?

Thanks a lot!! With a small knife I was able to reopen the whole of the mic so the sound could be received again. It solved the issue. You may dial *#*#3424#*#* and select "Audio Test" to test quality of all 4 microphones.
Thanks!

I've got a problem as Cantata. In stock apps microphones works nice, but in apps as snapchat or whatsapp sucks. Apps uses front microphone and recordes good in about 1 second, but after app mutes micro. Any help?
