To fix this issue permanently the audio IC chip must be replaced by a qualified technician as this repair requires a high degree of difficulty and precision. Furthermore an additional jump wire must be soldered on to permanently make good connection in case the chip becomes loose again.

How did my audio IC break?

It’s widely believed the problem is ultimately due to the phone bending at a weak point which happens to be where the audio IC is located, along with a couple of other important chips. When the motherboard inside bends, the solder pad connections to the flat audio IC get strained and eventually broken.

What does I²s stand for in digital audio?

I²S ( Inter-IC Sound ), pronounced eye-squared-ess, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device.

How is audio transmitted in an I²s system?

For stereo material, the I²S specification states that left audio is transmitted on the low cycle of the word select clock and the right channel is transmitted on the high cycle. It is typically synchronized to the falling edge of the serial clock, as the data is latched on the rising edge.
