Chuwi Hi8 Android Unusable with pluged in Headphones

[gary]

I started having this issue watching Netflix…was very annoying. My workaround was to use Bluetooth headphones.

Go to settings -> Application and uninstall Google Search. That is all 🙂 Work for me.

How to uninstall? I’m only be able to deactivate it.

Issue still there also with google search disabled 🙁

[Gogeta]

I have done:

Root the tablet

Install titanium backup

uninstall Google search

 

The problem still there. If i play a video on youtube, after few seconds pause and play itself. Like pressing a pause/play button on headset.

Work only with bluetooth headset 🙁

Great news!

I’ve got it!

After lot of hour of studying this issue, i have found that the headphone/jack send a Keycode to the system, like pressing a button on a headset. This keycode corresponding at HEADSETHOOK function that will play and stop youtube videos. I have changed this keycode to another!

We must have root access and edit this file located in /system/usr/keylayout/baytrailaudio_Intel_MID_Audio_Jack.kl

from

key 256 HEADSETHOOK WAKE

to

key 256 FOCUS

With this mod, issue fixed!

Next step, for my knowledge and for optimize this solution, is that i want to disable completely the headset recognition, i want to force only the headphone connection, but i don’t know where to start. May be recompile the kernel? how to do it?

Thanks!

This works, interesting solution. Nice work!

I have noticed this behavior as well. Although it only happens when the tablet is charging. When I disconnect the charging cable, earphones work normally. Both regular earbuds and those with stop/play button and mic. Anyone else notice this? I will try the fix mentioned earlier and see if that solves the issue

Try downloading soundabout from play store. With this app I can use my headphones.

Hi all. I found new solution. Buy USB to jack audio adapter (or DIY, there is no electronic elements, just simple cable) . Micro USB has audio signal in standard. In my chuwi Hi8 it works fine. Connect your headset to adapter instead in build-in jack.
