Is it a Dell with an ICH8 chipset? This is a well known bug and is fixed |

in alsa-1.0.15. I have this same problem on my Dell D830 which runs |

Gentoo and Ubuntu. |

On Ubuntu I use a backported kernel and |

'options snd-hda-intel model=dell-m42' in /etc/modprobe.d/alsa-base |

It's an HP dv6645us. I have ALSA modules built-in to the kernel. How can I set the model option with this type of ALSA configuration. |
| 27 |
If i choose to use the alsa-drivers ebuild do i include alsa in the kernel as a module or do i have to include it at all? |
