Internal mic volume too low in Android Head Unit (Fix)

Here are microphone level values
Level 0 - 220 Push Set (64)
Level 1 - 220 Push Set (112)
Level 2 - 220 Push Set (192)
Level 3 - 220 Push Set (112/144)
Level 4 - 220 Push Set (192)
Level 5 - 220 Push Set (192)
Level 6 - 220 Push Set (184)
Level 7 - 220 Push Set (184)
Level 8 - 220 Push Set (184)
Level 9 - 220 Push Set (184)
Level 10 -220 Push Set (184)
Level 11 - 0 Push Set (0)
Level 12 - 0 Push Set (0)
Level 13 - 0 Push Set (0)
Level 14 - 0 Push Set (0)

the above trick might not be 100% fix but if RCA cable is replaced and an external mic is added then it will give 100% improvement in mic volume.

In my case work. Firstly I did cut external RCA microphone and soldered directly on multi-connector pins. Secondly desoldered a built-in microphone (very simply operation). Then, Dont't forghet to wrap wires with alluminium thin foil and linked to the ground in order to shield from pick-up noise. Now works perfectly (my setting levels follow above values indicated from SP'S tech). Thanks.

Thanks mate what a strange place to have all these settings under USB l have been looking for these settings in the menus for months best wishes from Australia 👍

[abdulazizwafa]

Thank for such valuable video but i am facing the problem that the settings can’t be saved and everything turns back as before the moment i leave the menu despite succeeded change. Do you have any idea to solve this issue?

[tomsaji]

Thankyou! My mic audio quality improved a lot

[geordimaul]

What firmware are you running?
I’ve just got my unit so I’m just learning about them and yours is looking a different lay out

[sasamaric]

do you know how to turn on the subwoofer? I don't have extra settings anywhere on that multimedia

[TrioMardjoko]

Thanks... its not working in my unit. testing with whatsapp call, my voice still low. Happy to hear this help anyone except me.

Hello, great video! I have a different issue altogether, my android head unit is ZXDZ_01 and platform ac8227l. I may have altered the settings and now the reverse camera doesn’t work at all. Any ideas?

[IstvanMagi]

Thank you very much, it was a great help! It works! Interestingly, I have both internal and external microphones, but the change can be felt on the outside (although I have to turn the setting on). If I set it up, nothing works. If I set it on the inside, the outside goes and it fixed it. The point is that it has improved a lot! Thanks!

When I clicked on engineermode, it says "EM is an advanced debug mode, if you want entry to EM, please entry the Developer options at settings " what do I do

[DrejaRamone]

Sorry, but I don't understand this... What are those numbers that you shared in the description? And the one that says "Max vol. 0-160" is grayed out on 128 and never changes... And this is the only parameter that refers to the volume.

Hi
Thank you for your informative video
I followed your instructions but the Audio option does not appear in the engineer mode of my screen, what do you suggest to do in this case?

I have a lag when I talk on the phone through the bluetooth of the dvd. the person I'm talking to hears me 1-2 seconds late. do you know what i could do thanks!

[SraJr]

Anyway to get the fader to work? Because that’s the one DSP setting that doesn’t do anything.

[bestrealtorct]

All better. Got in with your excellent instructions. One more question. What are the best settings for the mic settings. I set mine on Level 5 -233. Feedback is the caller can hear me now but still sounds distorted or far away. What would be the best settings for loudness and clarity?

[noname]

In my case I am hearing other person's voice clearly but other person is not hearing clearly, what could be the issue ?

[alexgarcia]

Good video, thank you. One of the issues I see with the Chinese Android HU is the lack of documentations, and this type of videos are greatly appreciated. I just got a YT7260B with firmware J1.73, and one of the mayor problems I have is with phone calls quality. When I am on a call, I can hear the person OK, but they can’t hear me clear, he hears me with echoes and noise, it is like talking over a fan. The vendor recommends getting an ext. Mic, but some people are saying that an ext. Mic will not solve it, it must be with some setting or an interference with other Apps like Google assistance and “Hey Google”, that need to be off. I disabled it, but it did not solve my issue. I am wondering if anyone can give me some directions on addressing this issue. Thanks in advance.

[anthonmyl]

Thanks for the video!! Where can I by the cables?

[TheShuzi]

Hello, facing serious issues of noises and distorted mic audio on BT calls using internal or external mic. It's very hard to others to understand me when I'm talking but I can hear the calls clearly. The problem occurs only during driving, when I stop the car everything is perfect. I've already tried to replace the external mic and got the same results. The head unit is Joying JY-UQ135N4G-DA but I don't find any engineering mode as shown in the video to change mic sensitivity. Is it possible to configure mic settings in Joying head units?

[AR-blzd]

Thanks for the advice! However, my volume setting at Volume Level 1 is too high (level 1 sounds like it should be 6 or higher). Is this the same menu to adjust the minimum volume level as well?
