In this guide, we will show you the steps to fix the issue of the headphone jack not working in custom/GSI ROMs. When it comes to stepping into custom development, then it’s the ability to flash customized firmware that has been at the top of the priority queue for numerous users. However, there are still quite a few devices out there that don’t have active custom ROM support. Well, for those devices, you have the option to flash the Generic System Image corresponding to the custom ROM.

These GSI images just consist of the system.img and you would additionally have to flash the vbmeta to disable the verification check in most cases. While that’s well and good, the major issue is once the ROM has been flashed. Since these are not device specific but generic in nature, they aren’t explicitly designed for your device. So you might come across a few issues during the normal course of its usage.

In the past, we have covered about issues related to 5G, Bluetooth, 90Hz Display, DT2W, and No Audio in Bluetooth/Wired Headphones. And now, there has been another entry to this list. Numerous users have voiced their concern that the headphone jack on their device is no longer working after flashing a GSI ROM. The audio instead ends up playing via the device speakers. If you are also in the same boat, then this guide will make you aware of a nifty workaround to resolve this bug.
