[Realtek ALC269] ALSA test tone not correctly played back, still [possible solution included]

I submitted this as a bug back in beta 1. It was then marked as a duplicate as a similar (but slightly different) bug, and then it was closed. However, in the RC, it still doesn't work. Again, the driver seems to exist, but there is one slight problem with the auto-configure error. Here is what need's to be fixed:
