Help Auxiliary Audio Not Working

[Salt and Ducks]

Hello. I need some help.

I recently bought a Galaxy S4 smartphone and it doesn't seem like the auxiliary audio works. Not in our car and not with any headphones we use. It came with stock earphones, but I gave them away because they hurt my ears; I never tried them.


When I plug either the car's cable or the headphones into the jack port of the S4 smartphone, the sound continues to be played from the smartphone's own speakers, and no sound comes from the headphones or the car's speakers.


I see on the internet that this is a general problem, but I still don't understand what exactly the problem is and what the solution is. If I have to buy new headphones and new auxiliary cables for the car, then I'll return the phone, so that's really the last resort.

• Is there an app that can fix this?
  
• Are there some obscure settings I have to set?
  
• Is there a cable that I can plug in between my phone and my headphone or car cable to convert the signal into something that works?
  
• Can I have the smartphone modified by a technician?

My goal is to use my existing equipment with this phone. They work with everything else; there's nothing wrong with anything but this phone.

Thank you for your post. However, there are currently 23 different models of the Samsung Galaxy S4 and over 1,000 different stock Samsung firmware versions covering 3 different Android platforms. Not all issues affect all models or firmware releases and your answers to the following 3 questions may help in the forum's answers to your specific query.

#1 Could you post your Model number and Android version...

To locate these, go to...

Settings > More > About device > Model number and Android version

This will give you the model of Samsung Galaxy S4 that you have and which Android version you are on.


#2. Your current Firmware version, (this feature has been disabled on some models. If so, give your Baseband from #1, above)...

To locate your current firmware version, go to the stock, Samsung, dial pad and type in...

*#1234#

This will give you your, "Version", details in full, usually 3 lines of information which may all be relevant.


#3. Also helpful would be your carrier, (service provider), and if your phone is rooted or not and running a custom ROM, (give details).


Thanks. The above helps us to help you and hopefully someone will be able to reply to you shortly.



(Tip: You can go to the green bar at the top of this forum and click on, "User CP", which will take you to your User Control Panel and then select, "Edit your details", under the heading, "Your profile", on the left hand side. Here you can fill in your model and firmware under, "Current devices", in, "Additional Information". This ensures that your device details are shown under your user name on the left, in every post you make. You can update this as often as you like and will help other users immediately identify your current phone and firmware details.)

The smartphone is not rooted and I haven't touched the ROM. I haven't changed anything about it that wasn't designed to be changed, and I got it new from best-buy mobile.

 

[ironass]

I see that you are on the old Jelly Bean, Android 4.3, firmware for Sprint. You could try updating to the latest KitKat, Android 4.4.2, firmware release and see if that solves your problem.

I did the update, it didn't affect the problem.

Any other ideas?

Is your device in a case? Sometimes you'll have to push the plug in really hard to get it to work with a case. In fact, my case is quite thin, and I still have to push it in especially hard to make sure it's properly seated in the socket.

 

[Salt and Ducks]

Thanks for the suggestion. Even when I'm sure it's plugged all the way in, it still doesn't work.

I had sort of the reverse need - force sound to speakers even when something was plugged into the headphone jack:

The app ********** works for me. Can switch between the two modes with headphones in (audio routed to speakers and audio routed to headphones).

Wow. I typed the name of the app and it was replaced by asterisks.

**********

 

[electricpete]

did it again.

sound about
**********
sound about
**********

some weird censorship/substitution is automatically imposed by the forum.
When I typed the name of the app which is "sound about" without the space between, it replaces it with asterisks.
That's just bizarre.
