Hi,
I'm running Arch on Linux 3.10.6 on a MacBook Air 5,1 (late 2012).
Everything works mostly fine except for the microphone. The sound is provided by an Intel Corporation 7 Series/C210 Series Chipset.
I'm experiencing the following, very annoying issues:
1. After resuming from suspend, the microphone no longer works
2. If I enable sound chipset power saving, the microphone never works---not even straight after booting.
Two important facts:
* The speakers always work
* The microphone seems to be wrongly mapped. Mic doesn't show up under alsamixer, only mic boost. Furthermore, arecord only captures the microphone sound if I record in stereo mode---despite the fact that the mic is mono. The mic mono channel is mapped to the right stereo channel.
Any ideas? People with similar chipsets should be able to help me too.
