Comment 13 for bug 715877

I just tried your codec in an emulator, where it seems to work fine. If you run this command in a terminal: "modinfo snd-hda-codec-realtek"
Look at the filename on the first line - it should correspond to the path/file with Takashi's snapshot in. If you can't get it to work, let me know and I'll try making a dkms package for you to test.
