My MacBook Air has no output sound
my MacBook Air has no output sound, I have tried resetting the PRam, SMC and updating os, when I done a diagnostics on it error code VFF001
Apple의 MacBook Air 13" 2014년 4월 업데이트에는 참신한 듀얼-코어 i5 및 i7 프로세서와 더불어 배터리 성능을 약간 향상시켰습니다.
Same mbp, same error code VFF001. Also SMC reset did not fix.
Note however, I still have audio on the HDMI, like when connected to a TV. And I can use air-play, and possibly blue-tooth devices, like headphones/speakers. So these may be a work-around if not worth it to fix the mbp.
If it’s a MacBook Air, the Cirrus Audio chip is located on the IO board. Replacing the IO board resolves the VFF001 alert in most instances. If it’s a MacBook Pro, inspect the area where the Cirrus Audio IC is located - it’s not as easily replaced as it is on the Air.
The VFF001 alert doesn’t appear when the headphone port is dirty / obstructed, it usually only appears when there is chip/component/trace damage affecting the audio circuit.
