Z2 EARPHONES NOT DETECTED...again - Xperia Z2 Q&A, Help & Troubleshooting

Since update to marshmallow, the audio jack can't be used anymore. Had similar problem last year but it was quickly solved by mutiple times of plugging in the earphones this time it seems dead.Tried different earphones, no luck. The sound still playing on the phone speakers and not through the earphones. Sometimes a certain earphone would have sound but only on one side. Should i flash previous firmware? im not sure if it was caused by the update or the hardware problem. Phone is not rooted btw. Tried cleaning the audio jack as well. Any help would be appreciated

[Q] headphone jack not playing any audio

hello,
i dropped my phone into water, have since dried it off and recovered all functions.
however, the headphone jack and inverse camera have stopped working, i don't really care about the camera, but i really need the headphone jack to work.
i did a factory reset on my phone and the jack worked for about a week, then stopped. i assumed it was a hardware issue and ordered a replacement part, which i then installed, but the phone still wont play any audio. once i plug earphones in i can hear music for about half a second, which then cuts off, no matter how much i jiggle the jack or play around with the parts. i can see that the phone recognises that there are earphones in the jack, but no sound whatsoever comes through the earphones, so i'm wondering if this could possibly be a software issue...
anyway, im stumped right now, so any help whatsoever would be greatly appreciated. thanks in advance!
If you suspect that it's a software issue you could add information of what software you're using in the post. What version of android are you running, which audio player are you using etc.

[Q] Issue with Audio Jack Working Only On Some Headphones

Hello Dear Xda,
I am having a very strange issue with the Audio Jack. When I got my phone I used samsung headphones and they seemed to have worked perfectly. Now when I tried using other headphones - i.e. the ones that work perfectly with my other devices, it simply wont register. I put the jack in, but nothing happens. the music keeps playing. I thought its only that headphone so I tried others, such as my Car's cassette adapter still the same issue arises.
Now I tried my mothers phone which is a Galaxy SL and it works perfectly with all the headphones that wont work for me. then I decided to squeez teh headphone a bit harder and turn it around in different directions and it started to work a bit, with terrible quality, but it worked. and if i hold it into a certain awkward position you could hear the sound almost flawlessly.
I have came to the conclusion that my jack might have a problem. But I am not aware how to fix the problem. Cause it works perfectly with some headphones, but it wont with others. Does this requires full change of the jack, or can it be fixed by readjusting it somehow?
inb4: I have restarted the phone several times, changed to factory setting and even changed rom to no avail, so this clearly is no software issue.
Thanks in advance
Replace jack. Should be YouTube videos around/Google search might reveal how to do it, but in all honesty, if you're not competent with microelectronics (like me), take it to someone who knows what they're doing (local mobile repair shop). Shouldn't be expensive to fix as the jack is a cheap part, main component of the fix will be labour.

Headphone Jack issue after update

Hi,
Friends! I am having a very serious issue with my Xperia Z2 d6502. (never rooted) I recently updated it to official firmware .232 via OTA. Yesterday i realized that my device is not recognizing any headphone (original sony, other brands etc, all are working fine with other phone or laptop). Device is simply not reacting to any headphones, i even tried changing headphone type from sound setting.
I thought its faulty jack, but then I installed SoundAbout.apk and changed phone and media audio output to wired headphones, and then all headphones started to work but even the call tune is routed toward headphone by the app and its sounds perfectly.
Please assist me what is the nature of issue? is it hardware or what?

Strange issue with my headphones and HTC One M8

I have an HTC one M8 running stock 6.0 Marshmallow. I've been using these Amazon headphones for over a year with no issues. However as I was entering my house yesterday the music I was listening to all of the sudden stopped and whenever I plug the headphones in, any audio (call or music) plays through the phone's speakers.
I tried the headphones in my computer and they work fine. I also took another cheaper of headphones I have laying around to see if the headphone jack was the issue and I was able to get sound from the cheaper headphones.
I also tried rebooting the phone to see if it was some sort of software glitch. This whole thing is pretty strange. Any suggestions or insight would be greatly appreciated. Thanks.

No sound on speakers after LOS update (Kate)

I updated to the latest version of Lineage Os and my speakers stopped working, the back speaker and the front speaker. I can't hear when people call me and also cannot listen to music on loudspeaker, but I can hear everything with headphones. A little hand anyone?
Bro,I think Phone is stucked in headphone mode.
Try putting on earphones And pulling them out Of headphone jack a multiple times your problem will be solved.
If not then try blowing air in the headphone jack a few times and it will definately work.
I have also faced such problem but I solved by this method!!
