Today repaired my MacBook Air mid 2011. The charger and USB is working fine but my MacBook Air says their is no audio hardware. So I have no audio input or output from my MacBook Air it self anymore. Even if I plug in my airpods nothing happens. Airplay and bluetooth audio works fine.
I checked the installation of the I/O board and it is installed in the right way. After that I did a Safe mode boot, PRAM reset, SMC reset, a new OS instal and a complete disk repair. Nothing seems to help. So, the only left possibility is a hardware failure of the I/O board?
