Only by using its kernel, too. Then you would just copy the kernel (and |
| 11 |
initrd, if needed, but this might be a bag of problems if the initrd |
| 12 |
depends on stuff from the base system) from /boot and the according |
| 13 |
module tree from /lib/modules. |
| 14 |
|
| 15 |
I think it would at least be interesting what /proc/asound/version is |
| 16 |
like on the redflag distro. Also it would be interesting if they use |
| 17 |
in-kernel ALSA or separate drivers and if the latter is the case, then |
| 18 |
they might provide source packages -- which potentially include patches |
| 19 |
that add support for your device. |
| 20 |
|
| 21 |
Before trying all that: Did you had a look at the kernel log (use |
| 22 |
"dmesg")? Were there errors or warnings around the lines that were |
| 23 |
printed when the ALSA driver was loaded? |
| 24 |
|
| 25 |
When you emerge alsa-drivers, also make sure that there are no stale |
| 26 |
in-kernel modules in /lib/modules/$(uname -r)/kernel/sound/*. You can |
| 27 |
delete them manually, just run "depmod -ae" afterwards. |
| 28 |

| 30 |
|
| 31 |
look at the output of "dmesg" (e.g. piping it to "less": dmesg|less). |
| 32 |
However, for me (different card and all works well), there is zero |
| 33 |
output. You might change that by enabling ALSA debug output in kernel |
| 34 |
configuration, though... But I'm not sure whether that's worth it. |

The newer ALSA versions are at least supposed to handle the hda better |
| 46 |
w/ regard to supported hardware configurations. Doing a little |
| 47 |
recherche for the little I know about your laptop, I came across this |
| 48 |
thread: |
| 49 |
http://www.mail-archive.com/alsa-user@×××××××××××××××××.net/msg20707.html |
| 50 |
which seems to indicate similar problems which were partly solved by a |
| 51 |
newer version of alsa-driver. When experimenting with out-of-kernel |
| 52 |
drivers, always keep an eye on potential conflicts in |
| 53 |
/lib/modules/$(uname -r), and compare /proc/asound/version against what |
| 54 |
you think it should be. |
| 55 |
The thread also indicates that problems with HDA based audio is not a |
| 56 |
seldom thing to see. |
| 57 |
|
| 58 |
You can download newer versions of alsa-driver from their homepage and |
| 59 |
experiment with it in /usr/local/src. Currently they offer -1.0.15rc3, |
| 60 |
you might want to try it, it lists changes w/ regard to the hda driver. |

Yes, that's the culprit with distributed versioning systems. You have |
| 77 |
to download the full change history. I've not used mercurial recently, |
| 78 |
so I don't have a suggestion how to only download HEAD or something |
| 79 |
like that, if that's possible at all. |
| 80 |
|
| 81 |
I think at the moment there is no point in using a current Mercurial |
| 82 |
checkout. From what I see on |
| 83 |
http://hg-mirror.alsa-project.org/alsa-driver/ |
| 84 |
the last changes after 1.0.15rc3 don't matter in your case, so start |
| 85 |
trying that (as said, you can download it from their homepage). |
