** Summary changed:

- Dell Inspiron 1525, 
+ Dell Inspiron 1525 mic port doesn't work

** Description changed:

  I put 8.04 on my 1525 and I eventually got the sound figured out, and it all 
worked fine.
  I upgraded to 8.10, and sound output works fine, but the mic port does not 
work anymore. If I set the Input Source to Mic, I can hear sound from the 
internal mic in the front, but if I select Front Mic, I get nothing. When I 
mute and un-mute the capture level, it sounds like it's switching something on 
and off like it used to, but I get nothing from it.
  I looked at some guides here, but nothing seems applicable. I have gone 
through and tried a bunch of things in the Alsa mixer, but nothing has worked. 
I looked through the list of Alsa codecs, but there none of the drivers for 
SigmaTel STAC9228 seem to be the one I want.

  there was a fix suggested:
  The fix was to append "options snd-hda-intel model=3stack" to 
/etc/modprobe.d/alsa-base and to reboot.

- I will confirm that it works as soon as I can.
+ This fix worked for me.
