[Q] Nexus rear microphone?

Though Nexus 7 has two microphone, however I noticed that the mic on the left has never been used to record audio in any app, even stock camcorder record mono audio stream from the mic on the top.
Choosing "rear mic" in recording apps doesn't work as well.
So how does it work ? Is the problem of Android API or hardware?

i might be making a another face-palm here. but i think the bottom is for portrait mode and the top one is for landscape mode?
it could also be that one is used for recording and the other for noise cancellation? switching between the two while in use could be posing the problem?

Hardware is quite good
ALC5642 should be an HD Audio process chip, and it works really well in Ubuntu:

Directly record audio from two mic with arecord with channel>1, I got 32bit float, 192kHz PCM stream
For 4 channel, I got FL,FR, C(???where does it come from?) and an empty sream
FL=Left mic
FR=Top mic
The quality of recording and playback in Ubuntu is much better than Android :good: ,a simple command of
Code:
arecord -c2 -f U16_BE -r48000|oggenc -o recording.ogg -q 7 -
gives a better recording quality than most of apps in Android.

Exporting
I tried Dolby Digital on a different rom. I had trouble with Bluetooth working on that rom (LG Tone Pro HBS-750) and I don't have the problem on the Carbon Rom. So I am assuming it is this mod. But in all honesty, I want this mod. So is this mod in flashable form? I also want to add it to my carbon rom install and see if I still have the problem. I have read all the comments from this topic and I have searched for it too. Any help would be great.

can u please provide me with th emirror link of Sungsonic™ HD Anniversary Edition V-7 -SGS-TAB 2 7

How to get the most out of a 1 button headset

As someone who listens to music very often on my phone, I have always been jealous that iPhone users have so many choices of 3 button headsets that not only control media, but volume as well. There are some 3 button headsets that work for some android devices, but as far as I know, none of them work with the moto x. Personally I am looking for my headset to have 5 functions:
-play/pause
-next track
-previous track
-volume down
-volume up
I have recently figured out how to find a setup that achieves this with minimum inconvenience. There are many apps in the playstore that add more functionality to 1 button headsets, but they have 2 issues that I have have seen.
1) they allow the user at most 4 functions
2) they break the lock screen music controls that were introduced in ICS.
Problem #1 can be fixed by an app I recently discovered that allows you to program up to 5 clicks on your headset and therefore allows me the 5 functions I'm looking for. The app can be found here https://play.google.com/store/apps/details?id=com.shengande.degausslabs
There is unfortunately no way to fix the 2nd problem. There are 3rd party music widgets that can be placed on the lock screen, but they are inconsistent at best with google play music. The work around I have found is to use The app Nils lockscreen notification: https://play.google.com/store/apps/details?id=com.roymam.android.notificationswidget
This app can display the notifications you allow it to over the lock screen as a widget. I am only allowing it access to music right now, but you can allow it access to any notification. Now when I listen to music, my lock screen looks like:

I know there are other solutions if you're rooted or on a custom rom , but this will work stock. Hopefully this information is useful to those who want 3 button functionality on a 1 button headset.

The actual media player can have a great effect on that functionality as well. I use GoneMAD which has options that allow me to create whatever I want using just a 1-button remote with a variety of button presses/sequences, no extra app required.

True. I was going on the assumption that most people use Google play music, but I'm sure many are still using others.

2 questions new head unit install

Hi all-
at one time I was interested in converting a tablet into a head unit, but lacked the know-how so I finally just bought one from ali express and installed it; android 4.4 and I can't post links so you can
use the ali search and enter: 2 DIN Android 4.4 7 Inch Bluetooth Audio In Dash to find the specific unit that looks like

For the most part, it's great- but I have two questions that would make it even better
(1) I can play music and audiobooks (two different apps) over bluetooth, and the audio is perfect. When I get bluetooth calls though, it starts with a blast of static and then nothing- I assumed it was a mic or feedback problem, but I just played a voicemail recording from the phone AT&T "visual voicemail" app, and it did the same thing even though that is just playing a recording and shouldn't be using the mic at all. Does anyone know what if there is some other difference between 'audio out' apps that might cause some to work find, and others to have problems? There are rear ports for audio input, but I don't think those replace the mic, so for now I'm stuck with external troubleshooting (I'm not ready to take it apart and start doing surgery on the unit)
[EDIT: it also plays the audio from Google Maps with no problem]
(2) The unit has a very long splash screen- so long, that I can get out my 150' driveway and down the block before it goes away and allows BT to connect to play my audiobooks. I looked through the menus but haven't found a way to shorten that screen. I realize this may require rooting if it is not a publically available setting. Where should I be looking (or is it stored in a file somewhere?), and if rooting is required, how does a newbie like me figure out the best options for rooting, preferably leaving the rest of the OS as-is so I don't accidently jack up the reverse and forward camera functions, etc?
I'm not a frequenter of XDA, but this seems to be the most knowledgable place for this type of thing- so I appreciate you pointing me in the right direction
Many thanks!

I bought this radio on Black Friday of 2017 and ever since then it seems like it has just been one headache after another. I've done Desktop Support, been a NOC engineer, and currently pursuing my OSCP so I'm not computer illiterate; yet this makes me feel like I am. One of the things that interested me was the 10-band stock EQ. Then that was removed. Fine, I'll go to V4A. Nope. That doesn't work anymore. I knew beforehand that some of the buttons on the face wouldn't do what they stated they'd do but the option to reprogam them in the Joying settings only works on touchscreen buttons, not physical ones. The radio is fine. Just fine, could be better. Basically here's a short list of what I'm trying to do. I've tried more apps, APKs, and reflashes in the past few months than I can even begin to remember. I don't care how much effort this takes to get it going, as long as it just works. I don't know if what I'm asking for is even possible but at this point I'm tired of going in circles.
-A good, 10-band, virtualizer EQ that works on the entire unit. Something that will affect every bit of audio played.
-A way to reprogram the front-facing buttons.
-Preferably a better radio with HD funtionality
-A quick way to tether internet to the device. (I was using Bluetooth Tethering PRO but it made the unit super slow and unresponsive at times. Ideally gain connection by just plugging my phone into the USB connector but any way will work. I can't seem to get it to function. I'm on Verizon, which from what I've read restricts stuff like that.)
-A car launcher that keeps all functionality. (I was using Car Launcher AG but then I lost all functionality of the Bluetooth player unless I spammed source until I landed on it. Choosing BT Music only took me to the pairing screen.)
-Is there a way to replace stock apps? Like say I found a better app and wanted to replace a stock selection when Source scrolls through, could I do that? Like the Aux app for instance that has a video feed on it for no discernible reason
