7floor Sound Mod For MTCD

[typos1]

Pachis83 made it work on Android 6, and now I am working on a fork of his work. I think I've been able to bundle the jna .so files in the APK - it now installs. But since I don't have emulator of Android 8 with Xposed installed, I will be able to try it tonight when I get home.

I saw what is done in the code in order to work with Android 6. I will at least try to make it work on 7 or 8 - there's only Android 7 and 8 Malaysk ROMs for my device.

Here's my repository:
https://github.com/sparkybg/mtc-sound

It is already bundled there. It only needs building with Android Studio and makes an APK with .so's in it, which installs, at least on my phone and emulator. But they both don't have Xposed installed so I cannot tell for tthe moment if the problem with libjnidispatch.so is rectified.

Unfortunately I cant help, limited knowledge like you, but it seems to me just a case of finding how to make it recognise the lib, so I can only offer encouragement - it seems youre not far from making it work.

By the way, there isnt just Malaysk's ROM for your device, theres also Booroondook's and the SVA ROM, plus you can root the standard ROM, although I m not sure if it would work without mod on either of those. Also @Hal9k_ is working on an Oreo to, it ll be a while before its ready, maybe he could offer some help ?

No luck with bundling either. I think Xposed or Oreo itslf, or the ROM has something to do with it. It now installs, and does not look in XposedBridge.jar any more, but the status stays "Cannot find native JNA support". So definitely the .so file is where it is supposed to be, but for some reason the system cannot use it.

I did not know about it, so I'm trying to make a completely software solution in a modified MCU firmware, similar to a hardware solution from 7floor, but independent of a particular version of Android and not requiring Xposed

I am using your "SoundPatched" mcu update now. Let me know if I can be of any help.

Downgraded to Malaysk android 6 ROM - everything works and I am doing exactly the same with same .so file. I am out of ideas.

Is there Android 7 ROM for these devices? Possibly with Xposed preinstalled?

No Android 7 for RK3368/PX5 units.

You could try one of the other Oreo ROMs I listed above.

Sorry to hear that sparkybg, my Android/Java knowledge is pretty limited so I can't help you. At least you can use it with Android 6.

I hope cs-x(RU) will implement a software only solution compatible with Android 8.0. I guess it would be enough to "bridge" in any way the I2C buses (SoC-->MCU-->BD37xx); native sound control logic would still be functional but also we would be able to send i2c data directly to the BD37xx chip from the Android system.

Talking about MTCD and Android 8.0: I'm reading a lot of issues with bluetooth module if you have the MD725 V2 one. Did someone find a solution?.

Regards.

I have a mcu klyde, it would actually eonon with mcu code www. How can I make the change, compared to the images of the guide for KLD is different

I have noted that there is slight but clearly hearable background noise always when sound is coming from Android. When switching to Radio the noise is gone. When pressing mute the noise is gone as well. It does not go up when turning volume up.

I don't recall there were any noise after the mod but now after time has passed the noise is there. Does anyone else have any background noise?

I'm now trying to update mcu and hal9k mod to see if it makes a difference.

Have you tried re-soldering the connections ?

With all due respect to 7floor, this hardware mod is no longer needed to control the sound processor, thanks to Wadzio efforts, all mods in software.

 

[An92]

Yes, i installed this mod

Wadzio's mod is buggy on some units, plus every time a new MCU comes out it has to be modified before you can use it so this mod still has its place.

For KK, L and MM units at least. I m sure it could be made to work on Oreo relatively easily too.

I have 5.1 unit with RK3188 and I'm using latest Hal9k 1.3 mod with it. After I updated the unit to the latest 1.3 mod I had to do software part again to make this 7floor's hardware mod work.

I got it to work but with these problems:
1. Putting reverse gear in lowers the volume, but it does not return to normal level. (Workaround is to go in setting and choose not lower the volume but it is not what I want because it still kind of stays in the "reversing audio mode")
2. Very small issue: Bluetooth volume for calls is set to the max in the factory settings to hear the caller better. This causes very brief high volume cracking sound when the call ends and system switches back to radio or other source. It's not a big deal but annoying. Maybe some small delay could be applied in the switching part of the app?

Does anyone else have these bugs? Any solutions?

I am on Malaysk ROM and i have same issue with lowering the volume when switching in reverse. I have to put the same settings to "ON" to go back to the normal volume. Not sure if the sound is different after that though.....

P.S. if you don`t mind asking you, what software part you do in order to get a sound with Hal9k 1.3 mod because din not have any luck with sound on this ROM and 7floor HW sound Mod....
