Somebody in the thread at some point said: | Joerg, | Sorry about the wrong message.According to Len's report today, grounding | of pin6 at JK4401 is not work.
What about grounding pin 4 directly, did it make any change?
Maybe try this during a buzz call too, it changes preamp1 to use MIC2 instead of MIC1 in case the buzz leaks in somehow there:
echo "33 40" > /sys/devices/platform/soc-audio/codec_reg_write
We are meant to ignore preamp1, just a long shot.
