Hello, i noticed after a while of using, that there is a background music (like a menu jingle repeating) playing in very low volume, no apps are running in the background and I tried to kill every process and the background music doesn't stop. Anyone knows what that music is?

Thanks

Never had a problem like this. One reason can be that your head unit's radio interferes (change broadcast channel to transmit "white noise") or there is a program on Cardongle going bonkers. If this would happen to me I'd do a factory reset. Keep us informed what you found out.

Bye for now  Fred

@lupaiolis Hope you didn't install too many programs. Before doing a factory reset please write down the software and firmware numbers (I've got OS 2.4.64 and SW 2.3.86). Thanks in the name of all forum member who benefit from your findings.

Bye for now  Fred

@ap756 only thing installed is Torque pro, maybe is that but I don't reckon a menu song and also the app is forced close, is there anyway to understand the opened processes hidden in background

@lupaiolis First of all install "open settings" (DXIdev) from Playstore. If you can't find the problem in Android you might root your device (see Tutorials&Guides) and then you can be the boss of your Cardongle :-). By the way Torque pro isn't the problem (most used program on my dongle).

@ap756 please take a listen at the video

 
No apps running
No Bluetooth activated on the phone just hotspot wifi
If I lower the volume on audio settings using open settings app it doesn't change 

How to replicate:

Enable audio from Bluetooth to get the top right icon and tap on it

@lupaiolis Sure, I heard your problem. This is a typical electrical noise caused by crosstalk and electrical interference. What I can't interpret from your video is the source of the music and on which path this sound is injected. Will try to find the time to check my setup tomorrow. Probably this problem exists for all of us and we didn't realize until now...

@ap756 wait you hear just electrical noise? Don't worry about the electrical noise is my amplifier.. just listen when I press the Bluetooth audio button on the top right corner.. a music starts playing and keep repeating, I had to turn up the volume because the music is played super low volume

@lupaiolis Yes, this kind of music is electrical noise for me 😀 (just joking). Well, in technical terms there is an unwanted electromagnetic transmission from radio receiver (sounds like radio) to the Cardongle I suppose due to insufficient shielding of your radio receiver or Cardongle. One of both aren't fully compliant to the electromagnetic compatibility directive 2004/108/EC. Maybe repositioning Cardongle using an extension cable would help. If you cannot live with interference like that and you are not able to sort the problem with your head unit/amplifier you might discuss with Cardongle about sending it back. Sorry to have no better answer for you.

Bye for now  Fred

@lupaiolis Please carefully read my mail again. I'm sure you'll be able to understand. I already explained that I hear the music and I already explained why you and me can hear it. And you got an info how to do countermeasures. What else do you want to hear?

Bye for now  Fred
