Stereo Recording - Xiaomi Mi 6 Questions & Answers

Hello. Does anyone know how to defeat the problem with stereo? I record video but stereo is not felt. In the media info writes 2 channels of stereo but there is no sound on it. Tried to close the microphone one at a time, so the top one writes a bit silly, and the bottom one is normal but there is no stereo. How to be? Firmware 9.2.2.0
I understand the stereo does not work for us?

Bluetooth out of sync with audio?

Hello. I have a Desire HD with android 2.2.1.
Last year I had a HTC Touch HD with windows mobile. I bought a chinese copy of the jabra bt3030. The sound was out of sync with any video I could play. I didn't try with other phones, anyway I didn't spend that much for the headset, so I just sold it on ebay....thinking that that's why people don't buy chinese copies. OR maybe it was a problem of the transmitter of the Touch HD...so I didn't buy anything else and stayed with the normal wired earphones instead of having another stereo bluetooth headset.
NOW
I have the Desire HD, and bought THE ORIGINAL jabra BT3030. EXACTLY the same problem: youtube, trailers from MDB, .avi TV-rips played with rockplayer ---- EVERYTHING has this horrible out-of-sync audio which makes it impossible to watch even 5 second of a video without getting crazy.
I mean is that a problem of every stereo headset? IS that too much information to be sent to the headset? What can I do to make the sound sync with the video?
I have a stock rom.
Does anyone have this kind of problem? With which phone? With which headset? Is there any support forum for the Jabra BT3030 (it is the dog-tag one) ?
Last time it was a cheap 20$ chinese copy....this time is a retail 65$ boxed jabra....and I EXPECT it to work properly...
maybe you can set up the connection as new. or reset to factory settings
what do you mean by 'set as new' ? I paired the devices today for the first time. Reset to factory settings...is something i would rather not do
BT connections have a small delay.
You can try to set some BT settings to create a smaller buffer or something...

Click to expand...
Click to collapse
for instance? which BT settings could I adjust?
About the delay: i used until now a normal mono bluetooth headset, which is not A2DP so cannot reproduce media content (music or games sound and so on). There is a paid app on the market called BT Switch. This app redirects every sound of the phone to the mono bluetooth headset, allowing you to listen to music, hear the GPS directions, watch a video on youtube with the sound on the mono headset and so on.....well, there isn't any delay. That's why i can't understand why the stereo headset has so much delay....ok, it is stereo, more informations to send and so on...but the mono one has NO delay at all.
But of course a stereo solution with good earphones is much better than a mono with the low quality sound of every mono headset, which are built only to use the phone and not reproduce any kind of media sound...

Bluetooth audio only; still use phone microphone?

Hey All -
Here is what I'd like to do. I'd like to know if I can use my phone's microphone while in my car for hands-free, while still outputting the sound to my car's stereo through bluetooth.
Is this possible and do you know how well the microphone quality would be if it is, assuming the phone is mounted on the upper dash? Thanks!

Bluetooth Audio One Sided

When I connect to media audio via bluetooth in my car, I can only get audio out of the left side speakers. This is repeatable on different apps that play music. When I play a radio station in my car I get sound out of both sides.
What can I check to help diagnose this problem and hopefully fix it?
Thanks.
Does anybody else have this problem?
Does your car audio system support A2DP stereo Bluetooth profile ? Probably it does, otherwise I don’t think you can stream audio with just the Hands-free (HFP) profile (which is a low quality link meant only for calls). Mine works fine in stereo with my car’s audio system. Try deleting all the BT settings from your car and initialize everything from the beginning.
Iam verry sure that your audio car not support A2DP because in my car i can use for stereo...try to see the specification for your car audio bluetooth..
Sent from my HTC One X using xda app-developers app
It works fine when I use my Galaxy Nexus. This makes me believe it supports A2DP. This problem is unique to the One X for me. Did I get a bad phone?
Also, when I crank the balance over to the side that doesn't work I can hear it a little bit, but it's crackly and distorted.
EDIT: Problem solved. Re-seated the wiring in the sound system and everything is fine now.

[Q] No stereo sound in video recording

A quick search on Google and sample videos on YouTube reveal that the G3 is capable of and should record video with stereo sound, and yet I was disappointed to find out that my new G3 D855 does not record stereo sound in video no matter what I try.
I am also not able to record stereo sound on its own, any app that claims to be able to record stereo sound does not do that. ("Sound & Voice Recorder" by NLL, for example)
I am running official LG firmware (v21a) and I have rooted it in an attempt to modify /etc/media_profiles.xml to fix the problem, to no avail. I have also tried custom camera apps such as XCam LG, but that didn't help either.
Thanks for any help troubleshooting this.
Even thought its capable in my opinion yes it has 2 mics but 1 is for noise cancelling technicly u cant record stereo without 2 mics again in my opinion u need both a left and right channel. It might be stereo quality but tru stereo should need two mics for 2 diffrent reffrence points on sound i may horribly wrong and someone please correct me if im wrong
The mics are placed at two different points - one at the bottom of the phone next to the headphone jack, and the other is on the top of the phone next to the IR blaster. In this video you can see that there are separate L and R channels and you can hear the direction of the sounds that were recorded https://www.youtube.com/watch?v=dRrVcgr3Ps8
See everyone every told me that the top mic was only for noise canceling

I tried this same thing to so thats the mono sound in videos
I guess this could be a possible solution:

Static-like clicking from plugged in headset microphone

Hey guys, I just got a new HTC 10 (stock, updated to Nougat). I like to use a Sennheiser Game Zero headset for when I make phone/skype calls, but the microphone records a rhythmic static-y clicking. It does pick up my microphone audio, but the clicking is there on top of it. It stops when I mute the headset microphone via it's flip-up mechanism, but resumes when the microphone is unmuted.
I've used this headset regularly with both my PC and my older HTC One (m7) without the issue. I've also tried using a pair of cheap earbuds with an in-line mic with the 10, and it doesn't seem to have that problem.
For reference, here is a brief recording of the sound, uploaded to OneDrive: https://1drv.ms/u/s!Ai8_tx6LPas6h1-LZ0oNc-qBt9wP
If there's a better place to upload a FLAC recording that won't require outright downloading the file, I'll gladly re-upload it elsewhere for convenience.
Has anyone experienced this, or know what the cause/solution might be?
