If you have not already done so, check out the HDA documentation at: |

/usr/src/linux/Documentation/sound/alsa/HD-Audio.txt and HD-Audio-Models.txt |

Sometimes (usually?) alsa fails to detect the exact configuration of |
| 15 |
your audio chipset. You can force it to use a certain configuration |
| 16 |
when the alsa modules are loaded. For example, I have to use |
| 17 |
"6stack-digout" on mine. |
