With both 2.6.20 and 2.6.22 kernels on Ubuntu 7.04 on my Sony Vaio SZ240, I'm unable to get my mic connector working at any cost.
Well, almost...reading from /dev/dsp, I do see a minute change from 127 for 126 or 128 if I tap my external mic. This would imply the jack-retasking feature of this darn STAC chipset, right?
How can I change the jack retasking with the Intel HDA drivers or get further insight into this problem?
First, show the contents of /proc/asound/card0/codec#* files...

Thanks in advance, Daniel
