if your motherboard have 6 audio jacks (pink, blue , green , black , orange and grey ) and digital output at rear panel, you should try model=6stack-dig
Simple mixer control 'CD',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 65 Mono: Front Left: Playback 0 [0%] [-35.00dB] [on] Front Right: Playback 0 [0%] [-35.00dB] [on]
Make sure that you have muted those playback volume control of "CD" ,"Line" to reduce noise from those input to your output
Simple mixer control 'Channel Mode',0 Capabilities: enum Items: '8ch' Item0: '8ch'
only those motherboard with less than 4 output jacks need the "channel mode" control to retask some input jacks as output jacks
no, the motherboard has 6 plugs, but no digital outputs on the back. Furthermore, I muted the CD channel, the line in was already muted, but I still have crap sound compared to my $20 mp3 player. Something else is wrong!

Take a look at the block diagram of alc880 datasheet
does it help when you use hda-analyzer to mute the amp-in value from node 0x0b in 0x0c ?
Node 0x0c [Audio Mixer] wcaps 0x20010f: Stereo Amp-In Amp-Out Control: name="Front Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=0 Amp-In caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-In vals: [0x00 0x00] [0x00 0x00] Amp-Out caps: ofs=0x40, nsteps=0x40, stepsize=0x03, mute=0 Amp-Out vals: [0x33 0x33] Connection: 2 0x02 0x0b
I selected node 0x0c in hdaanalyzer and see audio mixer [OxOb] in the Connection list, but I cannot select the radio button.

I've tried model 6stack-digout and have no noticable improvment in sound. An ubuntu live cd yields the same result. The sound is good in Windows7. My friend says the audio sounds compressed. :(

I selected node 0x0c in hdaanalyzer and see audio mixer [OxOb] in the Connection list, but I cannot select the radio button.
According to the block diagram of alc880 datasheet, it look like two mute switches for node 0x02 and 0x0b or checkbox in hda_analyzer
Node 0x0c [Audio Mixer] wcaps 0x20010f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-In vals: [0x00 0x00] [0x00 0x00]
Unfortunately hda_analyzer seem fail to parse your codec -info

I selected node 0x0c in hdaanalyzer and see audio mixer [OxOb] in the Connection list, but I cannot select the radio button.
Refer to your screen shot , the mute switches of node 0x0b seem to be val[2] and val[3] of the input amplifier
muting switches val[2] and val[3] have no impact on the sound, it's still poor sound quality, there must be something else wrong....

Is that it, a sound card driver that sounds poor, leave it broken, and no way to fix it?
