Frequently Asked Questions (FAQ)

Following are some common questions related to USB C to AUX ports and 3.5mm Jacks :

How to fix the hissing sound from the AUX?

To understand how to fix this issue, you must first know what causes it. The culprit is called the “ground loop effect.” In simple words, it is caused when multiple devices are connected to the common ground through different circuits. This creates a loop of feedback which causes a humming sound that can be heard from your speakers and headphones. 

Now that we are on the same page, here are three easy ways to fix the hissing sound from the AUX cable. 

  1. Use a power bank to charge your phone while using the AUX port
  2. Use high-quality cables with appropriate shielding. 
  3. Use a ground loop isolator.

Is your USB C to AUX adaptor not working?

Here are a few ways to fix your USB to AUX adapters if they are not working correctly. 

  • Clean the audio port: Audio ports tend to gather dust particles. Your first move should be to clean it with canned air, or a cotton swab dipped in rubbing alcohol. It should get rid of all the debris that might be blocking the connections inside the port. 
  • Restart your phone: Sometimes, the audio drivers of your phone crash which might cause the USB C to AUX adapter to become unresponsive. Simply restarting your phone is another possible fix for it. 
  • Updating your OS: If the issue is still not resolved, there is a high possibility that your phone’s OS needs an update. It will automatically update your phone’s drivers too, which can fix this issue. 
  • Replacement: If the issue persists, cross-check the adapter on another device and replace it if it still doesn’t work.
