(BTW, just a curisotiy - would these surround and/or CLFE work as outputs?

The current auto-config code in patch_sigmatel isn't 100% suitable for the laptop-style configurations but rather for the desktop machines. So, we need a slight redesign of the configurator at first. Let's get things straight now. Please write down the pins you have on your device and what controls should appear. I suppose you have - a HP pin - a speaker pin - a mic-in pin What else? And, for these controls, we'll have - Speaker volume/switch - Headphone volume/switch - Captuer volume/switch - Input Mux but no Master (as STAC codec controls these outputs individually). > > I'm sure that this would break many other devices.

For example, we can add another field to indicate what is the primary output type (line-out, speaker, HP) and stop moving the pin information itself, so that the check of primary output is kept as simple as now, and the original information won't be lost.
