Pumpkin head unit attenuate instead of mute - MTCB Android Head Units General

Hey folks,
Is there a way to modify the stock system to attenuate the volume instead of completely muting it?
Cheers.

Under what circumstances?

Handsfree over the spreaker

Since I'm a lot on the road, driving, it's handy, when recieving a call, if the phone automatically is set on handsfree (speaker of the phone).
In the past there was the program from Oldsap to do this but the latest version of this does not work on my Diamond2
Does somebody know other free software for this? or,
Does somebody know a registry tweak or entry so the phone is alway's in handsfree modus, over the speaker of the phone?
Thanks in advance....
Try searching for touch_incall_screen_tweak in the forums.
Works well with my d2, just need to flip over the phone & it turns on the speaker, flip it back the speaker shuts of.

Flipping the phone when is placed in car holder, during driving, is difficult, don't you think.
There must be another way to do this...!!

Microphone volume too low...

Hi everyone!
I've bought an HTC Kaiser and when I make calls I've got to almost shout into the microphone, because people don't hear my voice.
I'm not covering the microphone hole by hand... Is there any way to increase volume of mic? I've tried various RadioROM's and it didn't help.
settings->system->microphone agc
turn it on
It's still too quiet. Any suggestions? Any registry hack or application?

Static Noise with joying 5.1.1 double din vw radio

Hi,
I recently bought a Joying Radio for a VW, it is a 8" touch screen and so far seems to work, I only have a really annoying problem with the noise. When I am not playing any music, the speakers emit a static noise, the volume of the noise never changes even if I turn up the radio. Since I am not always listening to music, I would still like to fix the problem. I read and the Sticky thread something about ground loop noise, but could never find an explanation to it. Maybe someone of you can help me
Also my weather app doesn't seem to work, if someone has any ideas
Thanks in advance, if you need any other information for solving this problem, let me know
How loud is it?
A very low static sound is common on these units. I have it both of mine. As you noted, thankfully the volume of the static does not increase with the volume so I really don't notice it when music is playing.

You can try:
- linking the metal case of the unit to ground wire;
- shielding harness wires, as better you can

The noise is not that loud, you only hear it if you are not driving and have nothing playing.
Is the ground wire already included in the VW cabling so that I have to pull it out of the harness or do I have to run a cable myself?
As for shielding I assume I can just take some electrical tape or is there anything else recommended?
Thanks in advance!
Hi kaitzo,
take a look at this thread of carjoying forum http://forum.carjoying.com/thread-24.html there is a link "solutions for radio bad reception" that can help for your problem too...
- radio1 subfolder has pictures about shielding wires
- radio2 subfolder has pictures about linking the iron case to GND

Hey, thanks for the reply, I already noticed that when I pull out the radio cable the noise is gone, so I am gonne give shielding it a try If that doesn't work, I will try connecting the ground wire.
I'll let you know if it helped solving the problem

so I dont care about AM/FM radio. are you saying if you just left the AM/FM radio unplugged you would have no noise at all?

Yes, leaving the antenna unplugged solved the problem for me, since I will be listening to Spotify most of the time anyway it might be a solution. Nevertheless, I will try to fix it even with the Antenna plugged in. Trying the ground method next, as shielding didn't help. I also found that the VW connector and the antenna connector which was included with the car not join each other all the way, so it is always a bit loose, but even with force I can't completely join them. I will let you know if I succeed.
And??
And after all you find a solution??? I’m with same issue
Having Same Issue
Hello there,
Sorry to revive this thread a few months late, but I am having the same issue and wanted to see if anyone had any ideas to fix it. I installed a Ownice C500+ radio head unit into a 2015 Nissan Murano. Everything functions perfectly and works great - expect for one thing. Whenever the volume is on, there is a very faint staticky sound in the background. It never changes tones or volume. It just always stays at the same pitch and doesn't go away. Aside from turning the sound all the way off, the only time it doesn't do this is when I switch to the radio - then the hissing disappears and all is perfect again. But if I am playing music via USB/AUX/Bluetooth, etc, (or if I just have the volume on with nothing playing) the hissing noise is always there. It is faint and hardly audible, so during driving it is no problem. But if, for example, I am listening to a soft song while stopped at a red light - then I can hear it and it is annoying.
I have tried to change the amplifier gain in the head unit because I figured that is what is causing the noise. However, it does not seem possible in the Ownice unit. The sound equalizer does not have "gain" as an option to change, I checked into Advanced Settings as well, also tried engineer mode on Android unit, plus downloaded some equalizer apps but nothing has fixed it.
Any idea on what is causing this and what I can do to fix it? Any help or suggestions would be greatly appreciated Thank you
Same here

Same issue here with a new Asottu Infidini Allwinner T8, with extra DSP chip included. Except that my hissing sound goes up with the volume. I will contact seller.

Sounds good, I will keep working on it as well - let me know if they happen to find out what is causing it
Same issue here : (
Solved!
Asottu provided an android 7.1.2 update weeks ago. The issue is gone now. It was not an MCU update. Just Android.
@lorrys
I'm glad that fixed it for your system - I will look for an update to the Ownice unit but I don't believe they have one to go to Android 7.1.2

I did find a solution that essentially makes the problem almost disappear. If you have an Ownice C500+ unit, go into Settings, enter 1260 as password to go to hidden settings, enter the volume area, make all of those values as low as they can possibly go. Some of those will be in the negative. When you reboot the system, the sound is essentially inaudible and that solves the problem.

I have the same issue but with Toyota version of the unit. Can you share the update?
i think the issue is the am/fm antenna, get a noise filter antenna adapter, might solve the issue
hi, I have an eonon ga8161, it would be hct px3 7.1 if I'm not mistaken.
I also have the background volume problem, but it is almost inaudible.
the most obvious problem is a rustling metallic type rustling noise, which is heard when there is processing from a USB device, both pendrive and USB dashcam ... someone has had this problem, because it is very annoying

lower sound in reverse

Hi guys,
I have a MTCD KGL unit, using a current stock ROM and MCU. Is there any way to lower the beeping sound in reverse? After installing the unit two things happened: 1) the sound for the back park distance sensor is very loud and 2) (even more annoying) the beeping continues for about 2-4 seconds after shifting into first gear. The car didn't do that before...
Any ideas? Thanks in advance

XTRONS hissing/buzzing after Alpine upgrade Audi TT Mk2

Hi all,
I recently swapped the original Audi TT concert Radio for an XTRONS (the one that looks like an RNSE Reference Number is IB79ATTRP). Now the Unit works very well, especially after the modded Amp was installed. Yesterday I swapped the original Speakers and Amp with an original Audi Sound Plus System (by ALPINE). The sound quality boost is immense, though it is creating a hissing sound that is constant all the time. It wasn't there prior and when I turn the unit off it is gone, so I guess it is a problem with the XTRONS. When I crank the music up it is not really noticeable, but when the music is low it is very annoying.
I don't really want to drive around blasting music 24/7
Any help is much appreciated!
What did reseller suggest when contacted for support. What has been tried from the other threads in MTCD section (if your unit is an MTCD)
Teh crickets.

I wonder if you were able to fix the buzzing noise. I installed the xtrons 10in and I have kinda the same issue. When I turn on the headlights it lowers the buzzing noise down significantly. I thought it might have been my JBL amp so I tried lowering it but its still there just lower.
