Hey guys,
my sound works, but only through headphones and my internal mic doesn't work.
I got my sound working using this guide: http://ubuntuforums.org/showthread.php?t=205449
I already tried to find the correct model using this one:
And I looked up my model here:

I tried:
options snd-hda-intel model=hp
options snd-hda-intel model=laptop-hp
options snd-hda-intel model=intel8x0
options snd-hda-intel model=hp-dv6736

and some others I forgot. I also tried:
options ac97_quirk=hp_only

But nothing seemed to work.

charly@lucy:~$ cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20549 (Venice)

I want to phone my girlfriend in Germany, I'm currently living in Japan. I'd be really happy if someone could help me.
Thanks in advance,
