Comment 33 for bug 582199

Next step: Trying a patch file.

I'm attaching a patch file, please put the file in the /lib/firmware directory. After that, add this line to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel patch=optiplex-380-patch.snd-hda-intel.fw

(If there is already a line starting with "options snd-hda-intel", add "patch=optiplex-380-patch.snd-hda-intel.fw" to that line rather than having two separate lines.)

Then reboot. The card should now be functioning from start without having to use hda-analyzer.

In addition, I think that BIOS has mislabeled Line In as an additional Mic input. In the patch file, there is a command that tries to override this mislabeling. Could you please confirm that
1) You have "Line in" and "Front mic in" to choose from as input
2) Recording from both line in and front mic work as expected.

Thank you!
