[MOD][MCU] BD375xx Sound Processor

[Jules_1606]

I was able to modify the apk so that it works fine on android 10.

The app works on Android 10.
However, the subwoofer can no longer be controlled separately.
Is there already a solution for this?

Love greetings

You may throw away your subwoofer - you'll get more space in your trunk and you'll have your problem solved. Don't say thanks)

@roomey
Many thanks

Can somebody make a soundmod on a newest MTCE_MX V3.78 mcu?

Another question is, why don't the developers of the firmwares implement this function?
Technically it's possible.

Give them a shout, see what they say?

So, let's do it.
Everybody who wants it, too, has to search for email address of the developers to get in touch with them.
Post it here or send me a pm.

Then will follow the next step.

If it's helps....
If you use hal9k mod, you can go to you EQ and activate "loudness".

Give it a try.
But let the EQ be "flat".

I don't fully understand this. All I know is my sound used to be alot louder before I updated the MCU .... I attached the newer firmware it's got which is MTCE_KSP V3.71.

I've gone from Android 9 to 10 now to 11. I assume you can somehow patch this MCU file to increase bass/treble etc to make it louder and thats probably what my original one already had.

False assumption.

Read forums.

Hint levels in Factory settings.

How did that work out

So I presume you'd just increase system etc in the Factory Settings area volume wise ....... I'll try that and see if it helps.

Hello
Question about a PX5 device with Android 10

1. Does the BD Mod work with the Hal9K Mod 5 ?
2. Which BD MCU (variant MTCE_GS) is the latest and where can I find it?

Thanks very much

If anyone needs APK for android 10, this should work.
The other APK published here (which changed targetSdkVersion from 22 to a higher value) could not work, because settings weren't changed because of a change in permissions from SDK 23 onward.

If it can't be found in the forum, you create it.

Note Mod applicable to the basic 'non dsp' units.

Any chance you could upload a set of these that'll work with Android 11? I'd really love it if my new coreboard would sound as good as it did with the old one!

Have you tried the one I sent?
The simulator I used when debugging a few things on it was based on Android 13, so it should have no problem running on android 11.
I can't say for sure tho, maybe on actual hardware there could be some kind of compatibility issue, there could be for example some change in the API that breaks communication with the MCU.
Also, you obviously must have the modded MCU to use the app.

Can anyone mod this MCU ?
thanks!

This did not work with Android 10

Just for completeness I would like to add cross-reference to some findings about Bluetooth module Swap here.
Some users are stuck with MD725 Bluetooth module as it is not compatible with later Android versions. It is possible to replace it by WQ_RF210 or FSC-BW124 module though.

Unfortunately this sound mod seems to be incompatible with those mods in some way. When a modded MCU is used then there is no audio during Bluetooth calls. There is no ringtone audible and when picking up the call no voice is audible on neither side of the call.

I have tried modded and unmodded MCU and it seems to apply only to modded ones. See my findings here. So the MCU mod somehow is breaking proper call audio routing.
