Not everything correct.

Here's what you'll need to do, even before soldering anything (you may solder later):

1. Copy libjnidispatch.so to /system/lib and set permissions to 644.

2. Check if you have files i2c-0 .. i2c-4 under /dev directory. If they exist (typical for RK3188) skip step 3 and proceed to 4; if they don't exist (typical for RK3066) proceed to step 3.

3. Copy i2c-dev.ko to /system/lib/modules and set permissions to 644.

4. Install MTCCSC.apk as a normal APK, it will appear in modules in Xposed Installer, enable it there and reboot.

5. After reboot, go to Xposed Installer, modules; tap MTC Custom Sound Control. It will open and show the status (see below for possible statuses).

6. Install SoundControl.apk as a normal app (no need to place it to /system/app or elsewhere).

The statuses that can be dislayed by Xposed module:

•	No patch detected – either MTCCSC module is not active in Xposed, or device was not rebooted after activation.

•	mcu,No device driver i2c-dev – you have device which requires i2c-dev.ko driver, and you forgot to copy it where needed or set permissions (see step 3 above).

•	mcu,Exception com/sevenfloor/mtccsc/I2cBus$CLib – you forgot to copy libjnidispatch.so or set permissions.

•	No access to /dev/i2c-?; <some additional info> - despite existence of driver, failed to access i2c bus programmatically. Normally should never happen, but if happened, contact me for further investigation.

•	mcu,Error in write() 11 (no response from i2c slave) – programmatic access to i2c bus works well, but Sound Processor does not respond. Need to check soldering.

•	mcu,Error in write() 110 (no response from i2c slave) – same as above.

•	i2c,Channel x (x- number) – everything is good, enjoy your sound.

Radio Stations lost

on malaysk ROM I randomly lose Radio station presets, even though I set the xposed module to remember my radio station.

sometimes they are remembered even after disconnecting electricity to the Head unit and some other times I just lose them after a simple reboot

It becomes really annoying to lose all my stations so often, any recommendations? How do you guys deal with it?

Screen problem

I have problems with the screen on my Klyde unit. It has a narrow vertical stripes, more visible on light backgrounds.

That happened for the first time before my summer hollidays, and I was able to get rid of this after a few resets, and display was OK for a some time. So, when these stripes occured, I made a few resets and I lived through summer.

But now they are constant, always on same places of the screen :(

Furthermore, sometimes while powering up, the screen it totaly white and it turns to normal after a while just by itself.

I don't like this, and I think my screen is faulty.

What type of screen should I look for?

What I know is that it's 7 inch (160x100 mm), probably Hannstar HSD070IDW1 series, with 60 pin connector... there are a lot of these screens on aliexpress, but I want to be sure this will work.

Did anyone change the screen, any information is welcome?

Well friends. I just discovered JetAudio. To hear in the Forum of this I googled program Malaysk ROM and tried it.

I didn't know that my Skoda Octavia speakers could sound as well. It is a marvel.

But I have two small problems:

1-When I return to starting the car JetAudio shows me the last track listened, but STOP. I have to PLAY again to listen to it.

2-When my navigation program playing instructions, JetAudio is until they finish. And I have activated the GPS Monitor. I have looked in preferences, but I have not found how to fix it.

I have a Joying brand Unit with the Malaysk custom rom.

Also, when I use google maps to navigate and listen to music with poweramp the music stops on every announcment and the first few seconds of the announcement get cut off.

Long story short: How to enable audio mixing?
[MTCB Android Head Units Q&A] mike.s:
This is probably user error. You have not followed the often given instructions to record all of your MCU settings before flashing a new one, then restoring them afterwards. Wheel3 in Factory Settings is set incorrectly.

This should not be an issue. The powerup state of the sound processor is with no volume, so without the corresponding software changes, you would get no sound.

Naturally

The default power-on state of the Sound Processor is at all channels muted. If something doesn't work, you'll get no sond at all. Is that is healthy for your rear window? :)

And after that, the software could go wild and blow it out. The question is, is my software less reliable than Chinese :) That's a joke.

By the way, why do you need an installation that could potentially destroy your car, without some kind of hardware limitation of output power?

May be you better turn knobs on your amplifier(s) counter-clockwise?

Thanks!

And what about BT, what exactly do you mean?

---------- Post added at 10:50 AM ---------- Previous post was at 10:30 AM ----------

What future support do you mean?

I use it daily in my car, and if I find any glitches I fix them and provide update to community.

Also, I monitor user's reports for the same purpose.

Two or three bugs were fixed since very first version (the version 1.1 is the latest so far).

From the "number of features" perspective the software is completed, I think.

So if everything works for you now, you'll need no upgrades in future (except, I guess, if/when manufacturers roll the Android 5 out for our units - the SW part probably would need an update due to Android platform change).

Here's the risk: I will definitely not jump to Android 5 just to be "on the edge"; I will wait for it to stabilize on our units; and this, in turn, means that there would be no Android 5-compatible version at instant.

And to answer your last question:

I think they just don't care.

They get all the software from Microntek (whoever they are).

Microntek could make it already if they wanted to, without changing hardware at all, but they didn't.

I was trollin about the rear window. i've got a monoblock, powering 500watts rms to my sub. that's not enough to blow my rear window :angel:

but still i'm a bit scared things get out of control and might want to go back.

maybe i should just shut up and perform the mod, test it and if i don't like it undo the mod (if that's still possible)

[MENTION=3590033]Malaysk[/MENTION] I keep getting random reboots on the latest rk3066 800x480 build.
[MTCB Android Head Units Q&A] 7floor:
Yep, you're right. I already have explained this, but on 4pda.ru and in Russian. Let me try to translate that to English quickly:

The sound processor that is installed on our devices, the ROHM BD37534FV and analogues, including commonly used BD3702FV, has the following functions:

•	Three-band parametric equalizer with adjustments of gain in range -20dB – +20dB, frequency and Q-factor of the filter in each band.

•	Configurable loudness module with gain in range from 0dB to +20dB, and adjustment of filter frequency and the level of high frequencies suppression.

•	Setting of subwoofer output, including selection of signal source, cut-off frequency, phase, and gain.

In the stock implementation, all the above is ignored and is not supported:

•	Instead of 3-band parametric equalizer, we have a 9-band graphical one, with strange logic – each of three groups of three bands controls a single hardware band, averaging their values. I guess it is a child of Chinese marketing. And the adjustments range is only +-10dB.

•	Loudness compensation does not use a built-in hardware circuit, but just adds some bass and treble, which is a way not the same.

•	Subwoofer output is fixed and cannot be configured.

Besides of that, in stock implementation, equalizer presets apply to any input, be it System, Radio, DVD etc. My experience tells me that it is desirable to have a separate equalizer settings per input. The Radio sounds differently than Media Player or DVD, so it needs to be adjusted differently.

In addition, a Preamp value that can be found in Factory settings was pulled for live adjustment. It is needed to equalize the volume of different inputs.

In my personal setup, I mostly benefit from hardware Loudness control. It really allows me to comfortably listen to music at high volume levels.

The Bass and the Middle are at 0 for me, because I paid attention to select my loudspeakers carefully and adjust my external amplifier to sound best at the flat equalizer.

I added some 5dB to Treble, as I'm in age at which my ears aren't the best in perceiving Highs :)

If you have an idea of what is the AFC, you may install the SoundControl without any mod.

Play with equalizer controls and watch the green AFC line.

It is not the funny toy: it is a true approximation of equalizer AFC using 2-order Butterworth filter model.

You'll see how your AFC changes as you move the controls.

Feel free to ask anything that was not clear.

It is absolutely possible: undo the HW mod and uninstall both software parts - as simple as that.

I'll tell you what I did for the HW mod: I made it with a little bit more wires and two jumpers, so that now I can switch i2c control back and forth without soldering iron - I needed that during my experiments.

on the 2nd pic, there's 4 solderpoints. what does SCL and SDA mean?

on the 3rd pic, there's a red line stating the 2 resistors should be removed, while there are 2 additional resistors connected together with 2 purple wires?

are teh gray and white wire from pic 1 the same wires connected to the 2 purple wires on pic 3?

Heyhey!

I've been reading "alot" about Spotify and it's issues.

I've been using three HU's this far, and have experienced similar issues with all three.

1.

Spotify crashes.

Spotify works great for the 1-2 first days, but then it keeps crasing. The solution seems to be using PCV Startup Builder, but I haven't seen anyone posting if it actually works.

Does it?

2.

Spotify doesn't cache songs!

This is quite the inconsistens issue. It can work for a day, or maybe a week, and suddenly all the offline playlists have vanished.

The "solution" is downloading it again, and praying to God, Allah, Krishnu (Or whoever your god is), that it works for another week.

Does anyone experience the same, and can someone confirm any of the mentioned fixes?
[MTCB Android Head Units Q&A] 7floor:
Duh... My pics are more confusing than helpful. It's because I've made them while experimenting, and they really don't show the final mod. They mostly show the place where the soldering occurs.

So, let's maybe try with this short manual.

1. Find the Sound Processor, it's 28-lead IC marked BD37534FV, BD3702V or like that (different units use different analogs).

2. From leads 25 and 26 of it, using a multimeter, try to trace out the resistors connected to these leads.

3. Unsolder these resistors (on my photo, they're said to be removed), flip them 180 degrees and solder (place like two bigger resistors on the same photo), solder wires to free ends of the resistors.

4. Find the WM8731 IC on the board, it is also a 28-lead chip.

5. From leads 23 and 24 of this IC trace the resistors.

6. Solder other ends of wires to these resistors, to their ends that are opposite to WM8731. Refer to schematic: BD37X(25)-resistor-wire-resistor-WM8731(24) and BD37X(26)-resistor-wire-resistor-WM8731(23).

I've explained as clear as I could.

---------- Post added at 12:16 PM ---------- Previous post was at 11:58 AM ----------

Definitely no.

:) Even not sure how to answer. Attaching a logic analyzer to the I2C bus and watching how the MCU controls the Sound Processor, while refering to the manufacturers datasheet for it, is that enough to tell what the MCU does and what doesn't? From the other hand, decompiling all the framework and vendor apps and finding every possible command that can be sent to MCU gave me a comprehensive list of what can Android software tell the MCU.

As to Viper, it adds DSP filters with different effects to the Android sound system, it doesn't control any hardware. Could you change the sound of Radio with it?

I'm not convincing you to use my work, but want to ask you why you don't want to use Xposed? Just curious. Has it some negative effect for you or why?
[MTCB Android Head Units Q&A] Tung_meister:
I've deleted the files but the problem is still there and the unit reboots when opening the door or opening the vehicle App. I think the problem is "simple VW canbus" is broken in this build. If I turn canbus off it works fine.
[MTCB Android Head Units Q&A] OneCheekyDevil:
Your future support will be greatly appreciated by the community here. Sad to think the Chinese makers wouldn't consider implementing the soft/hard mod. (have you tried emailing them?)

I guess every time malaysk updates the ROM, we'll have to re-implement your mod.

Just one more question. Do you think there'd be any side effects of adding the link wires without breaking the link from the MCU? (Other than maybe confusing the sound processor with getting information from both MCU and Android)
[MTCB Android Head Units Q&A] DJCannonball:
yes you did :) thank you for that.

i'm not complete confident to perform the mod yet at this moment.

Another thing I'd like you to consider is the fact that many images that you recieve look grainy right?

Another reason I recommend Textra, since it doesn't do this. One time I received a fulll sized 5 mb image. I was thoroughly amazed.

Back to your mod request, unfortunately I don't have the experience to know how to do such a thing. I'll take a look to see if it's a simple xml edit or something, but I doubt it. You may want to pm an experienced dev, like mikeyXDA.

I really appreciate your and other developers hard work, but frankly, as [MENTION=5362341]bharathbondfire[/MENTION] put it, there has been such a flood of ROMs lately, but none of them offers enough stability and RAM management to make it a daily driver. I personally tried every ROM for kitkat, but got fed up and went back to ICS and I am much happier.

I`m not saying the bugs are your fault, but instead of making heaps of new ROMs, wont it be better to improve upon the ones that are there already?. I for one would love to have a Carbon build with better RAM management and stability, no matter how much time it takes.
