--- Comment #24 from Raymond superquad.vortex2@gmail.com 2011-01-06 03:15:18 CST --- alsa seem only implement the capture devices only
do you have additional capture device (hw:0,2) ?
arecord -l
Take a look at block diagram of alc889 datasheet and the codec-info section in the output of alsa-info.sh
Ten DAC channels support 16/20/24-bit PCM format for 7.1 sound playback, plus 2 channels of concurrent independent stereo sound output (multiple streaming) through the front panel output
The "6stack" or "6stack-dig" model connected both HP and Line Out (Green) to the front channel [Audio Output].
you need to implement a new model "6stack-dig-fronthp" which connect your alc889's alt_dac_nid 0x25 to HP out at Ext Front and modify the driver to create stream_analog_alt_playback (device 2) and create the volume control/switches
0x02, 0x03, 0x04, 0x05 [Audio Output] connected to those four [Pin complex] Line out at Ext Rear ( Color = green, black, orange ,grey )
0x25 [Audio Output] - connect to [Pin complex] HP out at ext front
