From Openmoko
Waveform of GSM interference on GTA02v6 (?) while calling. Left channel is Mic1 (no headset connected), right channel is Mic2 - both with Mic1/2 Capture Volume set to 3.
Mic1 audio is the only one routed through ALC_MIX and the external capacitor; Mic2 audio directly sent to right PGA. "Mic Sidetone Mux" is set to "Right PGA".
