It's a Realtek ALC3271. I don't see any model options available for this, but I checked the code and it has the same codec vendor ID as ALC269 so I tried all the model fixups I saw in alc269_fixup_models with no luck. However, I noticed something interesting; when I enabled the "dell-headset-dock" fixup, the noises got louder, and I noticed a pattern. It seems everything else I do in the laptop results in a noise; moving the mouse, pressing a key on the keyboard, even a cursor blinking on the screen results in a distinguishable noise. After a while the noises lower in volume, as before, but the patter is still there, is just that I hadn't noticed. Any ideas? -- Felipe Contreras _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
