You are missing the correct sound driver for your hardware. |

You could use Google to find out which kernel module is required for your |
| 61 |
hardware; or, quicker and potentially more accurate would be to set up *every* |
| 62 |
driver as a module in your kernel and reboot. The correct module will be |
| 63 |
loaded and will show up in dmesg and lsmod. Then you can deselect the rest |
| 64 |
and rebuild your kernel. |
