Hi @PapayaSinMiedo  sorry to hear that you are getting that experience when using headphones together with a dongle. Well I can tell you that I use a dongle (usb c to jack 3.5 mm) on an Android 10 and never had the same issue as you describe here.

Do you have a chance to test with a headphone that don’t need the dongle to connect, in other words using a 3.5 mm jack connection? 

It might be that the dongle is not compatible with your device even that you mention it works in other app’s.

Also I would double-check on Android settings if there is anything you can turn off to avoid the auto-start.

I have a Google Pixel 6 smartphone. 

 

When I connect my headphones through usb c dongle (aux to usb c) My Deezer app start switching songs nonstop. It switch forward. It doesn't happens with Spotify or other streams apps like Netflix or outdoor products Youtube.

 

Also every time I connect the dongle it start google assistant. I tried to deactivate the assistant but still no difference. 

Using headphones through a USB-C port can sometimes present various issues. Some common problems and their potential solutions include: If you plug in your headphones, but there is no sound, ensure that the headphones are compatible with your device and that they are correctly connected. Try unplugging and reinserting them, and check if the volume is turned up. If you experience poor audio quality, it might be due to issues with the headphones themselves or the audio settings on your device. Try using the headphones on another device to see if the problem persists. Sometimes, USB-C headphones may experience interference or disturbance due to electromagnetic interference. If possible, try using a USB-C dongle or adapter with a built-in DAC (Digital-to-Analog Converter) to improve audio performance. Not all USB-C ports are designed to support audio output. Check your device's specifications to ensure that the USB-C port supports audio….
