It seem this patch also affect gigabyte ma78lmt-us2h motherboard with 6
audio jacks

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5346


M61PME-S2, G41M-ES2L and GA-880GM-D2H are motherboard with 3 audio jacks at
rear panel

motherboard with 3 audio jack should try model=3stack-6ch or 3stack-6ch-dig
to create a "channel mode" to retask blue and pink jack as outputs

For alc8xx  may need to extend channel mode from "2, 6" to "2,6,8"  to
support 8 channel with HP at front panel as "side speaker out" and the three
audio jacks are rear panel
