USB audio

Hello Guys,

First of all, I am truly amazed by all your work and effort to make these head units better. Thank you! :good:

Anyway, this is my first post here, so bear with me. I have an Eonon GA5151 (KLD) unit, running the latest FW from Malaysk, and the latest MCU. I would like to connect a USB DAC and play music through it, but I can't sort it out. I have an iFI Nano iDSD, it has a built in battery. It works fine with my tablet (CM11) and my phone (Z1 Compact, running Lollipop), but I can't make it work with my head unit.

I've started my adventures with this post: http://xdaforums.com/showpost.php?p=55224281&postcount=3162

I've copied the modules, they are all loaded OK. I've added a startup script to init.d so they load at boot. The last part, I had problem modifying the audio.primary.rk30board.so file to change pcmC0D0p to pcmC2D0p, because there is no pcmC0D0p in my file. The audio.primary.rk30board.so in the archive attached to the post is much more smaller than the file I have. Overwriting the file on the head unit with the one in the archive is not an option, it does not work. USB Audio Player Pro and USB Audio Recorder Pro reports that my kernel supports USB audio, but something is still missing. In other players if I connect the DAC the music "goes away", but I can't hear anything in the headphones connected to the DAC.

With "ld /dev/snd" I can see my DAC (pcmC2D0p).

With "cat /proc/asound/cards" I can see that the C2 card is the iFI DAC.

I've continued with this post (thanks to google translator): http://pccar.ru/showpost.php?p=251689&postcount=102

While the thread is also truly amazing, I could not get my DAC to work with "option 2". Instead, I got my head unit in boot loop. :) It must have been my ignorance, asound.conf on the head unit seemed more "recent" than the one attached to the post, I've overwritten it anyway. Maybe if I had used more recent Alsa files it would have worked?

Could you guys point me to the right direction about USB audio? How can I enable it? Which modules should I use for the latest ROMs? How can I redirect the sound properly? Is there a custom ROM which supports USB audio without modification? I think it would be a great addition to any car audio.

Thanks in advance!

Just updated to Malaysks latest ROM for 1024x600 and TomTom Europe is now working.

Perhaps anyone should correct the message quoted from the first side of this thread.

[MENTION=3590033]Malaysk[/MENTION]: thank you so much for your effort!
[MTCB Android Head Units Q&A] peti007:
I have the GA5151 (originally Klyde) too and I'm interessting in USB DAC, but I don't have the knowledge for this.

If it will work, the volume knob and SWC volume buttons will work with USB DAC too? How does volume control work in these HU's? I think it's different then on an native Android tablet because the MCU. Am I wrong?

Mic & buttons illuminations

Hi Guys,

FYI, I've fixed the BT mic using Nir's (dnts) excellent guide and just want to share that for me the silkprint naming of the capacitor that needed de-soldering wasn't C32 as described but C1C2 (see attached picture)

Secondly I've updated my MCU & firmware to the latest versions (4.4.4. June 10 ,MCU 2.55) and somehow I've lost the cool illumination of the unit's buttons and knobs ,When i try to activate them in the setup->element they turn on for 1 sec and than off , did anyone encounter this?

My original MCU (2.47) worked fine with the lights so i guess this change is somewhere in between , I can try to downgrade version until it works but i'm afraid to lose something ,Does anyone knows what are the changes in the latest MCUs ?, how far should i go with the old versions before i get sacrifice stability / sound etc' ?

I'd like to say HUGE THANKS for everyone in this forum and especially Malaysk for his great work and dnts for his Mic solution!!.
[MTCB Android Head Units Q&A] boecki1:
Thanks. I found the Mistake. i use the radio with German Translate. And there is the mistake. The Point -> Reverse is in Germany translated with "rearcamera", so that you think, you could turn on / off the rear camera.... :(

But now it´s working ! Thx !

Save settings and restore after upgrade

Hi,

I am currently on malayks june 7 rom with KLD 2.55.

I want to upgrade to june 28th version.

How can I save all my settings and home screens shortcuts? After I install the new version all of my settings will be eraesed. I want to recover all the settings and home screen shortcuts.

Thanks.
[MTCB Android Head Units Q&A] ojuniour:
Honestly there is no point having these unit comes with any mechanical drive anymore. DVDs andCDs days are long gone. I still don't know why they still include such..

Also in regarding to the new MCU firmware (for KGL) the hardware key led color seems to be in reverse and also it won't stay lit for more than 3 second or so. It sits of automatically.. The only time I can bring it to turn on again is to go the the element setting and tinker with the settings.. But again it still won't stay on for more than few seconds. Anyone having this problem?
[MTCB Android Head Units Q&A] mike.s:
Titanium Backup is your friend.
[MTCB Android Head Units Q&A] anyuzo:
Yes, I remember from the Mazda forum. :)

I'm also not sure about volume control, and I have a hunch that the head unit's CD player and Radio app won't work over USB. That would be totally acceptable for me, I would like to use USB audio for HQ music only. Something like this: head unit --> minidsp usbstreamer --> signal processor --> amp --> speakers

[MTCB Android Head Units Q&A] MayfairDROID:
When you go into recovery, does your screen work? If not, I would pull the unit and remove the front panel and verify you connections are good. There were some early production models that the white clip holding the screens ribbon cable would break for no reason. There is discussion of this, and the fix, on the first page.

hi, wonder if anyone can help me achieve this:

Basically bought a 2nd hand device off eBay Ga5153

the old user had tom-tom go on the device and paid £35 for 3 years so have a long membership

is there anyway i can update the device and keep the tom-tom membership still on the device?

device currently on 4.2 but wanting to go to 4.4 kitkat

Thanks
[MTCB Android Head Units Q&A] MayfairDROID:
It shouldn't be an issue. Just flash 4.4.4 rom, and then reinstall TomTom from app store. Should retain your paid status.
[MTCB Android Head Units Q&A] adilsec:
so do i not need to even do a back up? because thats the only thing i need to keep on the device

You must delete previous versions of MTCRadio, MTCmusic and MTCvideo from a folder System /app and not rename them !!! And only then copy the new version of the application to and reboot the unit!

Hello informative people!!

Not really seen any info on this but I have a KLD RK3066 unit with 2.55 mcu, I have the factory firmware installed and plug in a USB 3g dongle from Three network UK. All works without any input from me so I can use google maps/waze to navigate. 3g comes up in the information bar at the top.

If I install the superb rom from Mr Malaysk I cannot access or even see the 3g dongle. I can use wifi ok but there is no 3g....

Any pointers as to how I can get this working?

Thanks
[MTCB Android Head Units Q&A] ojuniour:
There is no such sung as "key light" in the factory setting. The closest thing I see there is the RGB settings.. That's about it. Are you on KGL?
[MTCB Android Head Units Q&A] mike.s:
Thanks! Any chance that, for those of us using SuperSU, you could add a simple change?

It's looking for the string "install-recovery-2.sh" in /system/etc/install-recovery.sh and if it's found, leave that file alone and create your file as /system/etc/install-recovery-2.sh You could also eliminate the

"/system/xbin/su --daemon &" line in your file.

SuperSU uses install-recovery.sh to launch, and will call install-recovery-2.sh after it does.

Here's the install-recovery.sh installed by SuperSU:

#!/system/bin/sh

# If you're implementing this in a custom kernel/firmware,
# I suggest you use a different script name, and add a service
# to launch it from init.rc

# Launches SuperSU in daemon mode only on Android 4.3+.
# Nothing will happen on 4.2.x or older, unless SELinux+Enforcing.
# If you want to force loading the daemon, use "--daemon" instead

/system/xbin/daemonsu --auto-daemon &

# Some apps like to run stuff from this script as well, that will
# obviously break root - in your code, just search this file
# for "install-recovery-2.sh", and if present, write there instead.

/system/etc/install-recovery-2.sh
[MTCB Android Head Units Q&A] mike.s:
Actually, that's much more complex, since you can't just add, except for the very first time. If a user changes their startup builder configuration, then not only does it still have to check to see if it's a SuperSU one (check for the text "install-recovery-2.sh"), but then it has to parse out and rewrite the SuperSU part before writing its own.

Since it always has to be checked, it's simpler to just to write an install-recovery-2.sh from scratch than to fool around with recreating the SuperSU portion.
[MTCB Android Head Units Q&A] mike.s:
So, " it is that simple, just add," except when you can't just add and have to parse for a special marker and deconstruct the existing file. OK, whatever - your definition of "just add" is different than mine.
[MTCB Android Head Units Q&A] clearchris:
You need the google login so you can download from the play store. Unless it was bought outside the play store.
[MTCB Android Head Units Q&A] devilsoft:
HiMike,

I will implement this into a new version of the app if I have time tomorrow. Is this also compatible with Malaysk firmware ? I know Malaysk firmware has install-recovery.sh and install-recovery-2.sh.
[MTCB Android Head Units Q&A] mike.s:
I'm not sure. I'm running a fairly new one, update_4_4_4_800X480_RK3188_2_MAL_NEXT_LAUNCHER_11_06_2015, and there's no install-recovery-2.sh in it, so maybe he's not doing that anymore.

Car record/ Daily roads

So today i started with a fresh newest image from Malaysk.

It is a very nice running image with good looks.

But again, my camera won't work like it should.

The way it is now it ain't usable at all.

On the original mcu 2,4 and android 4,2 it did work a bit better but also nog usable.

Malaysk 28.06.2015 firmware

Hi all first time poster, long time reader here.

I've installed Malaysk lastest release the : June 28, 2015 for 800X480 (Great work, looks really good. Love the JY apps).

However I do have a few problems, that I have not been able find a solution for via the search here.

First some unit info

I have an unit supplied from Eonon so called GA5166 ( I think it is a Klyde RK3066 with MCU MTCB-KLD1 ), the unit

sits in a BMW E53.

1. MCU

I used the provided MCU_KLD_1_Sleep_Musik.rar from Malaysk MCU post.

However I got no sound when I setup my factory settings correct again, after flashing the MCU. When I reverted

to MTCB-KLD1-V2.51 (from google drive), everything worked fine again. But then no delayed power off (sleep mode).

Has anyone any solution or even got this problem before here? Can I try other KLDs, is that safe.

I really wants the sleep function, the sound mod is not that important as my sound is pretty good now.

As my car is a BMW, it could be that the modded MCU does not provide the "Power up" signal to the AMP

and the radio antenna? This is an "issue" to be aware of with BMW (maybe other cars as well?)

2. My Huawei (E3131) 3G dongle worked fine with stock 4.4.4. But does not work with the rooted 4.4.4.

I think its safe to assume that it is not underpowered (i've tried the power hub just in case), as it worked fine before.

Does anyone know what I can do to get this one working again?

If not I'll start digging into the logs on the unit, to see if I can see anything there.

Only been playing with this release for a short time, but everything seems to work good and now the unit does pair with my BT ODB2 reader again.

Appreciate any help or tips on what to look for with these issues!

Cheers

[MTCB Android Head Units Q&A] Viking8:
Confused yet? Yup!

Hi everyone,

I have been looking into getting a nav system for my 2004 bmw x5 (e53), but it is really confusing which one to choose. I get that they all pretty much fall into one manufacturers line or another, even if the the reseller gives it a different model. But of course that makes things very confusing. How can a person tell what actual manufacturer has made a specific unit when the reseller has taken credit for making the unit and changed the original model number?

Is there a good, better, best between the manufacturers, based on quality products and support? What should I look for specifically, that would indicate a particular unit is upgradeable by the mcu/android firmware files listed in this thread? Has there been any new information that has come out about updated units with better hardware and possibly Android auto that would make me wait a little longer before taking the plunge and buying now? And finally, what in all of your opinions is the best place to buy one of these types of head units in North America?

Thank you VERY much, for any and all help you can give to me! :D

[MTCB Android Head Units Q&A] DiGiTY:
A creative and powerful way around this is to drive the headrests with a Raspberry Pi 2 running OpenELEC (Kodi/XBMC embedded OS) and using the remote control app for Kodi/XBMC (called Kore) from the head unit. That way you can control video (and music and photos) output and playback independently from head unit, free up head unit's resources and output HDMI or RCA. Kodi on the Raspberry Pi 2 can even stream media to the head unit (it can probably take a 128 GB microSD, unlike some head units, which is better for storage).
