Audio IC for Apple iPhone 6s Plus 64GB

The Audio IC is the central audio processing chip in your Apple Iphone 6S Plus 64Gb. It controls all audio input and output — including the loudspeaker, earpiece, microphone, headphone jack, and call audio routing. When it fails, you may experience total audio loss, one-way call audio, microphone failure, or headphone jack not working — all from a single chip failure.

If multiple audio components fail at the same time — for example both the speaker and microphone stop working together — the Audio IC is the likely cause rather than individual hardware components. Single-component failures such as just the speaker or just the mic are more likely to be that specific component. A technician can confirm with board-level diagnostics on your Apple Iphone 6S Plus 64Gb.

Yes — one-way call audio, where the caller can hear you but you cannot hear them or vice versa, is a classic symptom of Audio IC failure on the Apple Iphone 6S Plus 64Gb. Replacing the Audio IC is the standard board-level fix for this issue.

No. The Audio IC is a BGA or QFN chip soldered directly onto the Apple Iphone 6S Plus 64Gb motherboard. Replacement requires a hot air rework station, stencils, flux, and professional board-level repair skills. Attempting this without the right equipment risks permanent motherboard damage.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip is soldered onto the board it is considered used and is not eligible for return. For more information, check out SAHII's Return Policy.
