ACER A500 Microphone Fix? - Acer Iconia A500

Hi, guys Ive been looking for microphone fix on my A500 , when i record any video it has this loud background noise...which in fact my room is silent , also when I'm recording videos outside & using Skype . Im using HC 3.2.1 rooted with thor's CMW ver 1.5 . I been searching the forum for a fix but i cant find it or so as I read that they will fix this issue on HC 3.2, but still i get this issues . Is this a Hardware problem or OS issue?
Also can I still return this tablet to walmart & get a refund? I already exchange the first 1 cuz It got a charging issue. SO basically I'm returning an exchange tablet. It hasn't been 14 days yet. as they mentioned for returns & refunds.
Thanks.

Funny, I was coming here to ask for help about something similar...
In my case, I have a refurbished A500 which has been awesome so far, with the exception of the microphone. It records terribly, lots of noise and distortion in any recording I make (using Recorder as the test app I made a short .amr recording which I attach 7zip-compressed).
A friend has an A500, and it doesn't seem to display this issue. While it's no deal-breaker (I can live without recording audio...playback of tv shows loaded on the card works better-than-fine!), I'm wondering if there's anything I can do to fix it, or at least make it a little less...noisy.

I believe the culprit has to do with the speakers creating feedback. The workaround is to use headphones. Hope this works for you.

I did read that entire thread, which only tells me there are multiple unrelated issues around audio recording on the A500...these issues seem to get all mixed-together in that thread, with people who only care about Skype focusing on that and cross-talking to people who have completely different recording issues. I was hoping this thread could avoid the whole need-to-use-Skype distraction and focus on the specific issue of seemingly over-driven recordings. (With the refurb, I'm also out of the whole keep-complaining-to-acer-until-they-do-something-to-fix-it focus there seems to be on that thread. I can't really complain, and any warranty I had expired a while ago.)
The earlier suggestion to use a headset is, however, something I should have considered first (even read in the earlier Skype-centric thread), and am a little embarrassed I didn't. Sometime this weekend I'll pick up a cheap 3.5 mic/headphone set and see if that makes any difference. If it does, and the recordings though it are cleaner, I can be more comfortable it will work for one thing I care about...using the A500 with the SquareUp CC processor.

Mic - Solution for me.
Problem: Microphone recordings sound terrible. Soft, Choppy, Mechanical, like a bad cell call, bathroom (NOT the severe helicopter sound as others have reported). My hypothesis like others have suggested, seems to be noise cancellation issues. Especially since the issues vary app to app. These mics are right beside each other and I assume they're pretty much hearing the same thing, and the rear is trying to cancel what it hears, which is the same as the front! End result being filtering what it hears, ie filtering everything? FAIL.
Test 1: Using Recorder and Skype Test call, I tested different distances talking to the front/back, covering front mic, covering back mic, case on, case off, headphones plugged in/out, etc. In some instances you could hear some, and other hear nothing, some sound ok, some sound horrible. I wasn't satisfied with ANY.
Test 2: Popped off back of tablet and disconnected REAR facing mic. They are side/side, make sure you disconnect the correct one, the one with the diaphragm pointing out. Simple connector. Then tried Recorder/Skype Test call and both sounded Excellent. I have not tried a call with Skype, just the test. EDIT: Tested a real Skype call last night. No sound issues on my end or other end.
Conclusion: Removal of rear mic provided the best quality. There is zero filtering/cancellation/etc.

Gotta try this
Hmm!
Should of thought of this myself. Going to give it shot and post back later!
Unhooked the rear mike --it helps the front m ike is usable now. Not perfect but works.
So for me
1 Run Flexreaper ICS by Civato = better mike
2 Drill hole for front mike = not as muffled
3 Disconnect rear mike= almost as good as a phone but not as sensitive.
Okay on recording and search but Skype still noisy without headset.
Damn connectors were a pain to unhook.

I did and I agree this is a fix if you want to use recorder, Skype, talk, tango, etc. But I also learned to forget using the video camera UNLESS you have it using the rear camera (this is one you use by default when you Skype). Looks like it uses the microphone that points in the direction of the active camera.
So I would suspect the noise cancelling algorithm settings are to blame for poor sound recordings.

I solve this issue by using my stereo earphone with mic that came with my Nokia phone. I have tried a bluetooth stereo headset with mic and another wired earbuds with mic, there was either still a lot of noise or the sound level was very low. Basically, it is the same as using a headset. Finally I found one earphone with mic that works well. I actually have two of the same earbuds from 2 identical Nokia 5230. I tested them on two Iconia A500 with voice chat and video chat, it works very well both ways. I have also tried to turned off the Dolby Mobile as suggested by someone. It actually makes it worse and the sound level went down a lot.

acer a501 microphone fix
hi all
today i finally got to the bottom of the microphone issue
versions 3.x had some issues with the mic that cant be fixed - tried different internal and external mics but no good - i thought it was a hardware issue
and not able to solve but after ota update of ics the external mic is perfect - crystal clear and no noise and heaps of level.
the internal mic is crap so i decided to change the microphone with anything i could find - it has to be electret mic.
I had a few lying around and some worked well and some did not - i eventually found one that worked really well will heaps of level - the
only prob was that it was twice the size of the original.
i had to cut some of the plastic away but eventually got it installed.
The internal mic works great now - much better than the muffled one that came with the unit.
I left the second mic connected as it seems to make no difference in or out.
So what i have found -
firmware on 3.x no good for mic
ics makes mic work well if you use exeternal.
internal mic - get rid of it as it is useless.
hope this helps someone as i spent lots of time trying to fix this

OK but...

HoneyComb 3.2 disconnected the rear microphone, Resulted in Better Quality without helicopter noise specially better for skype Etc.
Video recording still Just hardly acceptable. but quality is still bad.
Wont buy from acer anymore.

Where's the mic?

Uhm, yeah, can't find it...
2 microphones actually. The user guide on Acer.com says "Dual microphone with noise and echo cancellation" and they are located next to each other along the top of the LCD. If you look closely at the top of the LCD while it is in landscape mode (with the docking port pointing down), you'll see the opening for the microphones. =)
man i looked for ages for these mics i still cant see squat. know they are there though as ive used em for recording, and for video calls
Do you have good mic performance in gtalk when on video call?
Mine was acting a bit weird.
They could hear me for a minute or so after starting the conference, but then my voice would fade away and they would only hear some backround noise.. sometimes they could hear me if would only talk directly into the usb host port lol!
When recording mic works fine. Havent tried skype yet.
Is this the case for any of you???
i had issues with the mic with the first a500 i got, the person on the other end would would hear a lot of static. But i've got the tab replaced and its been working fine now!
My mic performance is terrible. My wife has an I-pod 4, and her mic works great (using Hey Tell) sitting in same room, her voice on the Tab is great...mine on the I-pod is terrible. Hardware possibly? Any updates? Skype is terrible also...
Remidies?
Mic is pretty horrible. Often does not pick up voice to text and recorded voice is terrible. First mic is literally between the bezel and the glass in the middle top of the screen. Second mic is in sd card slot which makes no sense. Other than the size and weight it is my only real complaint so far.
my first a500 mic was horrible, it started off fine but after a little while it crapped out and the other side could not hear me, oddly enough whne just doing a voice recording rather than gtalk/skype call it was fine. anyways exchanged it for a new one this one works very well.
!!!???Nooooo
!!!Please keep your Ipod talk out of the android forum. Thank you very much ;(

[Q] Mic volume

I am having issues with the mic on the iconia. Volume is pretty low. While using gtalk the other side can barely hear me. Has anyone else been experiencing this?
Same here. Testing Fring and using the built-in mic or a headset mic, it is impossible to hear what I am saying. There is no mic adjustment in the Fring app and I can't find one in the tablet settings? Am I missing something that should be very obvious? How do you adjust microphone senstivity?
same problem with gtalk. It's sometime hard to hear what I say
I ve been having the same issues with gtalk. Havent tried any other voip app yet.
Mic works fine in voice recording apps though, so it can't be hardware related.
Maybe honeycomb issue??
Where are the mics?
i think the mic is atthe top of the screen in the crack dead center .click the vol up and click on the/pop up the middle i think is the mic volume .if/im/wrong sorry
I have the same problem on my galaxy tab 10.1 but mic volume seems low on all apps.
Just got the a500 and have experience similar results, mic volume is extremely low.
I have tried it with various voice apps, including gtalk, voice recorder, camcorder, etc, and the voice is really low.
Im begining to wonder that this is a hardware issue.
Is this issue consistent with all a500s? or only some models?
My mic is so low volume as to be virtrually useless. I tried plugging in an external mic and that was slightly better but not enough.
When using the voice recorder app I notice that the meter hardly moves off the stop, something wrong here.
I wonder if this issue is more common than it should be?
http://forum.xda-developers.com/showthread.php?t=1162054
But some people here have said their mic is fine. I am going to check a few out in the shops and see if they are any better. Really, at the moment it's not suitable for skype or google talk which is what I got it for.
I still think its a honeycomb noise canceling issue. Plug In headphones while u record and u will see the difference.
I bought a second A500 yesterday and the microphone records my voice far better than the unit I've had for almost 2 weeks. With the old unit I can barely hear what I speak, but the new one I can hear myself clearly. Manufacturing date of the old one is may, the new one is manufactured in april. It did not get the 3.1 update yet so it's still running stock 3.01. One other thing I like about the new one I just got is that the volume buttons work a bit easier and don't require as much force to push them down.

That's the key right there.
It's a software problem not a material one.
I experienced the exact same thing as you.
Bought a new tablet and tested the mic with stock 3.0.1. The volume was fine.
Updated to 3.1 and the volume was very low.
Well, my mic sucks in a big way. I tried many times to use google talk, tango and so on with horrible results. I have to yell like crazy and they can barely hear me.
So... as a lot of ppl are complaiing and it's a software problem, is it possible they do nothing to solve it????? It shouldn't be that difficult...

I opened up my acer and moved the microphone to the front because before when recordingi couldnt catch a sound coming from recording eg. a person talking.
Now I can at least hear the voices of the people im filming.
For gtalk and skype and stuff i use a headphone set with a mic via the headphones jack, much nicer.
Cheers!

You don't say things like these and not tell us the how's and the what's. For example, what headset did you use? How did you move the mic to front?
BTW, I'm on 3.1 and have never had an issue with the mic. Just did a recording while I was driving and talking. Still sounds pretty good to me.

There is actually a thread further back if you bother to look that I opened and described everything and also uploaded a video to see the mic improvement.
Edit: Here is my thread, http://forum.xda-developers.com/showthread.php?t=1169050
Edit: Headset I used is a brand called EXIBEL Art.no 38-4061, cheap and works PERFECTLY I can hear and be heard as if in the room.
same issues. Sound seems to just stop as well after I use camcorder
Mine works well on any app except gtalk. Although I recently installed voodoo on my rooted Galaxy Tab 10.1 and the mic adjustments helped. Without Voodoo I usually just plug in headphones when I use gtalk and that solves the issue 100%.

Hissing background noise when recording video

Hi,
Just got my new xperia arc and whilst it is a great phone I've found that there is a loud hissing noise (like rain) when recording video. I've uploaded a video to show the problem. Ah, just tried to post the link but I've been told I can't as I'm newly registered...
Others I've messaged have the same problem but there doesn't seem to be a fix. Are there any suggestions as this really kills the HD video function for me...
yeah I have the same problem, I think it got slightly improved with the updates.
try updating.
The phone is upated to the latest firmware t-mobile have to offer. I guess the only other option is to debrand and install generic firmware?
my phone is debranded, I tried uk, Global and Hong Kong, they're all the same.
So why isn't this problem more widely reported then? It pretty much kills the video recording capabilities.
I've experienced that too.
Try not to obstruct the first microphone with your right hand, the first microphone is at the bottom of the phone. Check if that solves the issue
It doesn't solve the issue, my fingers are nowhere near either mic hole.
I've also tried some test videos where I cover up each of the mic holes with my finger. I've tried covering up mic 1, mic 2 and then both. Now, strangely, when covering up the mic my voice does get a little muffled but the crackling/hiss does not change.
This indicates to me that this is a possible software issue i.e. compression of the audio or the way it is recorded, rather than the mics physically picking up the hissing.
If the mics were picking up this hissing (i.e. too sensitive etc) then covering up the mic hole would give some change, which it doesn't.

Low microphone volume?

Does anyone else have the person they are talking to mention how low you sound to them when speaking on the phone?
It seems like I have a low microphone on my nexus 4, unless the phone is directly in front of my mouth the person can't hear me clearly, I'm thinking it might be hardware but I know with some phones this can be corrected with a custom driver that makes the microphone more receptive
Is there an app or setting that I can use that would disable noise cancellation in case that's what causing my mic to make me sound low?

Actually I have the exact same problem - not sure what we can do to fix it.
If I crank up the volume fully it appears to -sometimes- solve the low audio problem.

Its actually on stock, so I just rooted it, and will try with a different rom shortly.
Same thing here.. Sometimes they hear me, sometimes they don't even during the same call..
I'm starting to think the noise cancellation is playing some tricks.
While driving home this afternoon I was on headset on the freeway, where those I talked to could barely hear me.
Unplugged my headset (klipsch s4 image ii), and sound was good. After a while I plugged headset in again, still bad.
When coming off the freeway I kept the headset on while talking - and all of the sudden it was crystal clear (using the words of the guy I talked to at the time). At the same time I noticed that I had no data (outside even edge coverage), don't know if that is related or not.
Is there some way we could experiment / disable or tweak the noise cancelling?
Ps: I have had the same issues without headset also, so definitely something general software things going on

I had the same setup. I am using the Xylon (stable) 15 ROM for several days now, and SO FAR I think the microphone reception is better. I haven't heard complaint from the person I speak to on the regular. *cross fingers* hope it's 'fixed' in some way.

That's exactly how my phone was as well. I would be on one call for a while and all of a sudden out of nowhere the person I'm speaking to says I sound like I'm speaking across a room and I'm like 'wtf happened? I haven't changed positions since I started talking to you!'
I did a little testing with the person I was speaking to as well, to test the microphone receptiveness and the mic seems to pickup my voice better, I wasn't speaking directly into the mic and they said they heard me fine.

I have a sneaking suspicion It might have to do with the noise cancelation as well, I think on paper whoever designed that feature on the phone thought it would be cool but it doesn't seem to be panning out too well. I've read somewhere on this forum about how to increase microphone volume and cancel the noise cancellation using the Terminal Emulator app and/or the phone's dial codes (#*#*some sumbers*#*#).
I have the same earphones (no mic attached) and I have similar experience but I haven't taken note of it like you have since 95% of the time I have my headphones in the phone.
I also want to mention a little trick that I think seems to work when on calls. Whenever I turn the phone over, screen facing opposite of me, I hear less complaints of me sounding too low to the other person. Maybe it's doning something... i dont know.
Same issue - with headset only though
I have the same issue, people really struggle to hear me on conference calls (which I spend a lot of time on), so I have to hold the mic in front of my mouth to speak which gives awful sound quality. I don't have this issue when not using a headset (phone mic works fine).
Nexus 4 + Klipsch s4a = really quiet mic, people can't hear me at all.
Nexus 4 = No problem, phone mic works.
Note - music playback is fine, no issues there.
My klipsch headphones worked fine on my GNex, no issues, so I don't think it is a problem with them. It has been an issue from the moment I switched to a Nexus 4. Have also tried other headset (samsung one that came with Gnex) - and have the same issue of sounding very quiet on the headset mic.
I did wonder if it was an OMTP vs CTIA issue, but the button on my headset works fine to answer/hangup/skip tracks/open voice search etc. so I don't think it is that.
I also tested with another Nexus 4 handset using Soundmeter and got very similar results on both handsets, suggesting it isn't a handset issue (though not a very scientific test).
Does anyone have any ideas?
Just In Phone Calls?
Hi Folks,
Is this mic issue just related to phone calls?
I'm using the latest CM10.1 nightly build and my mic is useless for phone calls.
However, Google's voice search works just fine and if I record a video my voice is recorded just fine.
I could be wrong but I suspect the Nexus4 can not use the phone jack for incoming audio.
In my opinion when one plugs a headset into the audio jack the Nexus4 camera microphone
becomes activated, not the headset one. And the Nexus4 cam mic is really bad.
Again, I might be completely wrong. (I hope)

OMG you have it reversed. What a mess!
I have yet to see Google Search understand anything I say and video sound is horrible. Call audio is great.
Hi guys - I am on stock android - same issue on 4.2.2 as on 4.2.1.
This isn't just related to phone calls, same issue on google search. I tested headset mic pickup volume when speaking normally with Soundmeter - around 35-40dB (what it calls a quiet whisper at 3ft to quiet residential area, Park).
I also tried moving the headset mic closer and further away from my mouth with the phone in the same position - with the headset mic virtually touching my lips it went to about 60 dB (normal conversation at 3ft) - so it does seem to be related to the headset mic. I can only guess it is either a dodgy connection in the handset or some noise cancelling functionality that is cancelling out my voice!
Any ideas or thoughts greatly appreciated

Darn it!
I knew I was an outlier.
No way I'm getting a fix for my issue then
Anyone figure out a fix? I'm having similar issues with my microphone.
Hooked as bluetooth device in my vehicle, other end hears me fine.
On phone call using speaker phone, other end hears me fine.
On phone call WITHOUT speaker phone, other end cannot hear me at all.
Using a sound recording app to record voice, playback of the recording I can hear my voice faintly if I was YELLING during the recording.
Shazam/Soundhound apps do not work.
I am rooted on rasbeanjelly/trinity kernel. I have to say this issue started a few days ago when I have done no changes to the phone. Already running the rom/kernel for weeks.
I've tried flashing back to stock rom/kernel and the same problems persist.
Any ideas?

Just an update, I unrooted and reverted back to stock and the problem went away, so it was defnitely a software issue. Will be trying other roms/radios/kernels and see if the problem comes back.
I was on rasbeanjelly 4.2.2/trinity
akira112, did you get any success with your experiments?
Guys, is there any progress / comments regarding this issue?.. Microphone itself works fine when recording the voice with some app, but during the voice calls it is the mess...
My Nexus 4 is two months old and is being returned to Google due to the microphone constantly cutting me out on calls to business clients. I've tried every trick from sound apps to custom roms. No joy. I'm hoping my replacement doesn't have the same problem (although given the sheer number of postings on this issue, I suspect a Nexus 4 design flaw)...
Hello
Is there any solution to low microphone volume problem?
I have been using my N4 for a week and some people complain about my voice's volume. There was no such problem with my previous phone (Defy). There is no difference whether I use phone's mic or bluetooth headset.
My Nexus runs CM10.1 with Franco kernel.
Also keen for a solution
I just returned my first N4 due to the speakerphone cutting out after a minute or two, and getting stuck in non-speakerphone mode.
The replacement seems to not have this issue, which is nice.
But now people are telling me they can hardly hear me. It happens both with normal mode and speakerphone mode.
Ridiculous.
I will be calling Google tomorrow to see what they say, but I am not going to hold my breath for a decent response. Judging by the number of people reporting this issue online, it's not something Google has a solution for.
If anyone figures this out, I'd love to hear about it.
Have sent mine for repair because of this problem. People told they could not here me well.

I have the same issue, couldn't fix it but what I noted was that any mic gain adjustments I made only applied to the phone's mic not the headset mic. That means that there is something else that modifies the headset mic, but I do not know.

Galaxy s4 audio water tap hiss in recorded video

Hi
I have a i9500 which I have enjoyed its high res images and full HD detailed images in 13MP (ozcan rom capability). Everything works flawlessly in my s4. Am not so sure what the problem could be when it comes to the recording of sound in video and voice recording.
I have been scrounging the net for a possible solution but realized that the s4 has a design flaw of pop and crack sounds when video recording. I do experience those but negligible. The sound quality recording is very good on the s4. My issue is it comes with an unpleasant water tap hiss that requires ambient audio to be a certain threshold to completely drown it like an ordinary conversation in a few feet from the microphone. This problem I encountered in both stock rom & ozcan rom.
The trouble comes in when you decide to record video in absolute or near silence. It will be very notable on playback at volume 10 but hardly audible at volume 4. This happens both in voice or cam recorder. Has anyone figured out how to rid of this unpleasant hiss?
Isn't anyone experiencing /has experienced this at all?
Hi,
I have experienced this while recording myself playing guitar, but I thought it was the amplifier hahaha. Sorry I can't help, it seems it's an issue with S4 itself, and if that's the case you can't do anything AFAIK. If I end up discovering a solution I'll update you on this, but I don't think I'll find anything...

Oh, I've just seen your reply, I hope am not too late. An in depth further analysis on the nature of this problem is, in the recorded video if you care to open it in a professional video editor, the left audio channel is the one with the distortion. The right one is crystal clear for my case with 0% hiss. In voice recording, only one channel is doing the recording and I assume it is the left one because the distortion is also present in it as bad. I'd like to here of your case though.
Just now I plugged in the earphones with the mic and voice recorder app automatically switched to using the mic on the earphones and this only happens in voice recording. Video recording doesn't automatically switch to external mic with the earphones plugged in, am not certain it is a video mic vs earphone mic compatibility issue. The good news is the earphone mic picks up very faint clear sounds even whispers in 1.5 feet proximity and WITHOUT ABSOLUTELY WITHOUT the distortion (water tap/whistling sound I get) that I get from the internal mic of the phone in voice recording only. Now what is the chance that it is my internal mic next to my charging port that is at fault?
After doing alittle more research right now, I have learnt that the voice recorder does its recording in mono hence has only one channel and the Video recorder does its recording in stereo since it has two audio channels (left and right). This now explains when it fails to use the earphone microphone as an audio external recorder.
Now the S4 has two different microphones as now seen by the video recorder's audio output. I have established that the culprit channel is the left channel. One simple test has now narrowed down which microphone is faulty. I ran the voice recorder app and placed my phone on my bed. I scratched with my finger really close to where the mic 1 (next to the usb charger is) then did the same to the mic 2 next to the earphone jack port. Thank God!! the audio recording has confirmed that it is indeed using the left channel which is the mic 1 placed next to the charging port. This gives me the chance to use this video to rectify the issue. My only problem is finding a genuine part because there are people complaining of quality issues with the replacement parts.

Hi there Kernel ranger! Did you manage to fix the noise of the mic? I'm having the same trouble. This morning I recorded a Koto concert from a distance and the left channel is plagued with some kind of electrostatic noise. Right channel seems ok, though. I think I will have to clean that rubbish with Ozone...

Am glad people with the same issue are following this thread. I'm telling you! I ran all the tests I could and confirmed 100% that my Microphone Mic Flex Cable Ribbon part needed replacement but before I could even do it, someone liked my s4 as it was and I sold it to them. What is your s4 model number? Now I got a Note 4.
What you can do is first get it cleaned with even rubbing alcohol if necessary, if this problem just started just recently. After cleaning it and the problem persists, you will have to get a repair kit like I did from ebay then order Microphone Mic Flex Cable Ribbon part to replace the faulty one. Youtube has tonnes of video about how to replace that part and it will only cost you $10 at the most if you do it yourself correctly.
