I have just done another test, and it seems my internal mic is now working
fine, at leas for now ;-)
To reconfigure the mic, before pulseaudio loads, I just created a small file:
/etc/rc2.d/S01mictest (and chmod 755)
With this content:
#! /bin/sh
### BEGIN INIT INFO
# Provides: mictest
# Required-Start:
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: set mic stuff
### END INIT INFO
echo reconfig audio `date` >>/tmp/test.log
echo 0x0e 0x411111f0 > /sys/class/sound/hwC0D0/user_pin_configs 2>>/tmp/test.log
echo 1 > /sys/class/sound/hwC0D0/reconfig 2>>/tmp/test.log
And now the mic seems to work after my reboot...
I'll attach my alsa-info, in case someone can use it to make a real fix.
Greetings,
Thijs.
