 Posted: Thu Mar 30, 2006 2:02 pm Post subject: Sound Card's problem of AC97 |
 |
|
| Code: | * Loading ALSA modules ...
* Loading: snd-card-0 ... [ ok ]
* Loading: snd-seq-oss ... [ ok ]
* Loading: snd-pcm-oss ... [ ok ]
* ERROR: Failed to load necessary drivers [ ok ]
* Restoring Mixer Levels ... [ ok ] |
And there are only two devices in /dev/snd, seq & timer
When I have mknod the follow devices controlC0 pcmC0D0c pcmC0D0p pcmC0D1c & pcmC0D2p, yet that.
My sound card is ac97 based on the nForce4 Ultra MotherBoard. With the module of intel8x0.
The modules followed snd_pcm_oss, snd_mixer_oss, snd_seq_dummy, snd_seq_oss, snd_seq_midi_event, snd_seq, snd_seq_device, snd_intel8x0, snd_ac97_codec, snd_ac97_bus, snd_pcm, snd_page_alloc, i810_audio & ac97_codec, had been loaded automatically.
I think that is the VANILLA kernel's error, besause that I have tried both 2.6.16-gentoo-r1 & 2.6.16-nitro-git9.
And there is no problem in 2.6.15-nitro3.

I have nForce4 w/ the same sound.
Do this:
Add the following line to /etc/make.conf
ALSA_CARDS="intel8x0"
Please use Gentoo sources and compile Sound into the kernel (not as a module). Do not compile any ALSA or OSS options into the kernel, just the base Sound and *nothing* else under Sound.
Then, after you compile the kernel and install modules, "emerge alsa-driver".
This will add the ALSA modules to your kernel.
Reboot.
Things will work well, then. See the rest of the ALSA document in the Gentoo Wiki.

I had a similar problem with alsa when i installed gentoo 2006.0 . As suggested in the udev manual and somewhere in the forum, i emerged coldplug and added it to the boot runlevel.
emerge coldplug
rc-update add coldplug boot
The problem got solved. |
