I have a eunavi PX5 4G/32G with an inbuilt VW Quadlock. The unit has following sound related issues (when in a Skoda Superb 2011);

- when no media is being played, significant background noise can be heard (white noise + clicks, etc). in particular, when downloading over wifi, the noise varies as the load on the CPU varies.

- visible engine noise in the rearview camera

- high level of background noise can be heard when media played from the USB, microsd and less noticeable with the radio.

when on the desk power supply,

- the is persistent low level white noise, but without the clicks, etc and no downloading induced noise.

- the low level white noise is persistent across radio, media, etc.

decided to bite the bullet, and open the unit up, hoping to install the DSP mod.

- Notably the amp chip is located next the power supply,

- the audio chip is on the rear side of the board from the powersupply / amp

- the clock does not have shielding around it, allow the board clearly was designed with that intention

can anyone identify the actual manufacturer of this board and help with the DSP mod

https://www.alibaba.com/product-det...ml?spm=a2700.icbuShop.41413.34.77eb1e36Nr5kPU

https://www.aliexpress.com/item/4000274050022.html?spm=2114.12010612.8148356.24.6030147dlf1vAh

I have updated the

- MCU to MTCE_HA_v3.40_1

- system to px5-userdebug 8.0.0.0 OPR5.170623.007 eng.hct.20190428.180147 test-keys

update went smoothly.

It would seem that the sound problems are a grounding and/or VW noise issue powered via the quadlock connector

(i note it is not possible to power via the quadlock connector on the bench - presumably because no canbus connected)

The big question is, can i install a DSP and will it reduce the white noise problem.
[MTCD Hardware Development] As7i:
I have the same media player with DSP, and have the same problems with background noise. Contacted the seller, and he sent me a new main board - the problem still exist, after replacing the board. The player is mounted in Honda Accord. Tried changing the capacitors - same **** different day ...

Will be following the tread if any solution comes up.
[MTCD Hardware Development] gwaitsi:
can you make a photo of the board and particularly identify where the DSP is.

thks
[MTCD Hardware Development] As7i:
No idea where the DSP is ... For me it is just a board with some elements and chips on it, no idea what is what. But there are the pictures of the board, if they could be in any help for you.

Copy and paste the link only without "<<<>>>" ... had to cheat the forum since new users are not allowed to attach or send links...
[MTCD Hardware Development] gwaitsi:
It's not the same board. It is almost the same, but obviously a different revision. Turn the rear view so your thumb is on top. bottom left corner. You are missing the audio ZL3560 chip and the one below it. slightly to the right of the ZL3560 you have a square chip but i cant see the number on it with the quality of your pic.

Do you here varying background noise when downloads are occurring over wifi.

i uploaded your pics for the benefit of others
[MTCD Hardware Development] As7i:
I have not used the WiFi yet. I had a varying background noise while I was browsing the menu, and every touch of the screen was reflected in the speakers. I gave the media to a repair shop and they changed all the capacitors. Now the noise from browsing the menu is gone, but still there is hell of a "turbo" noise. I can clearly hear my rpm in the speakers. And the problem is gone with other players. Tested the same player to a different car - same "turbo" noise. Tried a "hi-low" filter/converter - the idea was not to use the RCA out ... and the problem became even bigger.

Now the car is in a car audio service, the boys will try to fix the noise, or the medial will be replaced. If it comes to replacing the media unit, since the EUNAVI shop won't assist anymore, claiming that there is no way their media to have such a problem ... the defective unit will gladly be run over by my car ... several times - just to be sure it is dead ...
[MTCD Hardware Development] lennylen:
I've tried 3 different boards with and without DSP and the solution was to turn down the gain on the amplifier. I'm using RCA.

However, I noticed a significant improvement when I plugged the microphone into the back of the unit. Can you test this out and let me know? Both microphones broke on this unit, I'm not sure why, but the whining is gone until I turn the gain on my amp up. It sounds pretty good now, especially after tuning with the dsp board. I'll still be returning it though to try a Dasiata board.

Regarding USB audio: my eunavi board has terrible white noise pops clicks. My newest unit(CHS) has no issues over USB audio. It's flawless. Im thinking about using a HDMI to RCA converter for digital audio and hooking it up to a helix for auto digital /analog switching.
[MTCD Hardware Development] gwaitsi:
Interesting. From the menu, i also get basic touch screen noise. Downloading just makes it more prominent. I am use the ISO connector for Skoda.

I would say you probably have a ground problem if you are engine noise. You want to make sure, if using an ext amp, the two units are grounded together at the same point.

I will take a look at the caps as well.
[MTCD Hardware Development] gwaitsi:
I have a factory fitted blaupunkt amp and connection via the ISO connector. The gain is currently set to -12dB and the amp mode is set to auto detect.

I might take the oscilloscope out when it warms up and have a look,.
[MTCD Hardware Development] ELCouz:
I've been following noise issue on PX5 for a while (they all have them) but no one on this forum found the right fix (better ground, change caps, install DSP,ground heatsink of PX5, solder RCA directly nothing really fix it)

Did you solve the problem?
[MTCD Hardware Development] marchnz:
Could it be that the hardware is fundamentally flawed.
[MTCD Hardware Development] gwaitsi:
it's most likely a combination of cheap components e.g. capacitors, grounding issues and RF isolation/shielding and cheap design shortcuts. it is clear, if you disassemble the unit and move the screen away from the CPU & baseboard, there is less interference from the touch screen. Also supporting that, my unit has an onboard VW Quadlock so it direct plug/play. There is clearly engine noise which doesn't appear with the original blaupunkt unit. But you pay one tenth of the price...so what can you expect. the question is, if you can do enough e.g. add noise filters in line for the quadlock to reduce the problems to an acceptable level.

The bigger issue in my mind is the inbuilt malware. My unit tries to contact a tencent IP address, and also probes the ports on my firewall if i connect the wifi to my guest network ;-)
[MTCD Hardware Development] gwaitsi:
So finally, I bit the bullet and started to work on solving the issues.

First step is to reduce the engine noise on my 2011 Superb 3T5 Diesel,

which is also particularly amplifier when using USB DAB.

Two possible options

1) so-called camera Rectifier is a 1000uF/16v cap on the input side with a IN4001 rectifier diode and a small cap (probably 10uF not sure) on the output.

2) so-called car power Filter is an inductor with a 2200uF/25V cap on the output side of the inductor.

You can see on the 2nd photo there is an inductor and 4700uF capacitor. I didn't trace the circuit yet,

but I guess this is on the power input from the RCA connector strip and not the Quadlock/VW ISO connector.

I hooked up a scope to the Quadlock connector power and there was noise and a sine wave on it. Although the Quadlock diagram for the Superb shows

12 – Voltage supply, negative, terminal 31

15 – Voltage supply, positive, terminal 30

16 – Anti-theft coding control signal, SAFE, positive

I connected one box of 1) on pin 15 and one box of 1) on pin 16.

There is about a 1v drop on the power to the unit i.e. 14.1v to 13.1-2v but the solution solved the engine noise and significantly reduced the noise of the DAB.

There is still some screen noise, but I noise there is provision for RFI shields around the various components (which have not been installed). I will try to replace the PCB caps and add some shielding to see if i can cut the screen noise out.
[MTCD Hardware Development] marchnz:
What are the frequency(s)/period of the noise?

The inductor, what is the physical size?

Have you considered using a shottkey diode instead of the 1n4001?
[MTCD Hardware Development] marchnz:
OK, so youre unsure not sure how to design filters, select the correct components, including filtering and reducing voltage drops.

Not over analyzing, just knowing what the right path is to reducing switching noise.
[MTCD Hardware Development] gwaitsi:
I provided two links;

1) Half Wave Rectifier

2) Low Pass Filter

of course, you can do this with the raw components for a few cents.

But the two aliexpress links provide them in plastic packaging, which makes them convenient for installing in the car. The half-wave rectifier is a smaller package, so I installed that first. It solved the problem in a much smaller form (given I put in two - without having checked the onboard Quadlock connectors). On the design of my motherboard, it is evident there are no capacitors in the power rails connected to the Quadlock connector (which is the 68pin dual-in-line connector)

While the low pass filter will have less voltage reduction, in this case it makes no difference to the head unit as it is simply reducing the noisy 14v to a clean 13v which is still with range, so frankly, I consider that part of the problem solved.

Hi,

my wife got a Fossil smart watch for christmas and I kinda like the standard Fossil watch face.

I tried to look for something similar in the Galaxy store or at Facer but didn't find anything.

Does anyone know if there's a watch face like this for the Galaxy Watch (46mm) - especially with the clock font?

Hello is it possible to make the safety net issues undone with snapchat netflix etc. without any hiding tools like magisk etc.?

At last I used PIXEL EXPERIENCE ROM and now I'm flashed the original global eu rom for mi9t pro V11.03.0.

But I can't find netflix snapchat etc. in the play store, but root is successfully deleted and i have installed the clean original eu rom.

It means that my mi9t pro can be used normally with every apps like from fabric without any safety net issue.

Hope for your help, thanks

I have done it countless times, to check what is causing the volte problem.

Yes you can do it with stock recovery, because it doesn't matter!

You have to download fastboot rom, (download 10.3.3.0 or 10.3.5.0 if you want dual 4g option) (do not download recovery rom)

Extract the .tgz fastboot rom file and place it in your desktop folder (if you place it in any other folder, it may cause location not found error.)

enable usb debugging in settings and enter fastboot mode in redmi y2/s2 and connect to pc.

Launch mi flash in your PC, click select and select extracted rom folder, then click refresh.

[Android Q&A, Help & Troubleshooting] ColinOH:
Hello Everyone!

Due to finding no Ringtones to allot to my new email, and only a lot of files in that location, I stupidly removed the files to see if the ringtones would then appear. They didn’t”! I now seem to have deleted most of my photos in my Samsung Galaxy S4 Active mobile Gallery along with all the recorded data on my S Memo pages. And, probably, many other items that I have not yet discovered as missing!

I have downloaded an App called DiskDigger for photos. It has pulled up over 1,000 photos, some of which are duplicates or more. On wading through them and choosing an awful lot to restore, I am given the following choices where to restore them to - Bluetooth, Email, 3 named emails, Save as, Save to Drive, WhatsApp, WiFi Direct. However, once again I found a problem as I cannot move the number of my selected photos to the apps as there are too many chosen photos. I therefore took the second option and selected a named file.

That done, I found that they had ‘miraculously’ appeared in my Gallery! A further search and selection will, hopefully, repeat that.

I then downloaded an app that supposedly recovers documents named, strangely enough, 'Document Recovery'! It has recovered some documents which are proving a little difficult to open successfully to read. They go to a blank page after the indication that they are - 'Loading' - 'Opening' - then nothing!

I would also seek advice about a way to recover the details previously recorded on the S.Memory pages, if possible, (an app that works like a notebook where text etc can be written and saved.) and how to successfully open the documents recovered by Document Recovery and placed in an automatically named “All Recovered Documents” file.

Many thanks in advance for any advice!

Regards,

Colin.
