Comment 37 for bug 741825

Ubuntu 11.04 (freshly installed and updated couple of days ago), Acer Aspire 522, CX20584 sound.
no skype, no mic.
removing pulseaudio and using some pavucontrol, gamix etc. utils did nothing.

Partially fixed the problem by setting snd_hda_intel model=laptop, dell-vostro position_fix=0,1
at least now I have my mic (pink jack) works fine in skype and phones (black jack) are shutting down internal speaking when inserted

so all the buzz with this problem is in setting "wrong" models of PCs?
