Fujitsu P1610 Sound 82801G (ICH7) SigmaTel STAC9228

Auto-detected and uses the snd-hda-intel driver. The Fujitsu has a microphone attached to this sound card, but it does not seem to be auto-detected. A microphone attached to the microphone jack works well with the default kernel.

The microphone works with the following settings in alsamixer (or KMix)...

Input -- (Optional) Mux1 turned on, and set to at least 1/4 -- this is the equivalent of microphone boost, I think. (Optional) Capture1 turned on, and set high.

Switches -- (Optional) Mic as Output turned off (muted). There does not seem to be an ADCMux equivalent. To avoid feedback loops, I turn off the Analog Loopback (muted).
