 |
|
I'm trying to make the sound card work on my laptop. I've followed the alsa installation guide:
http://www.gentoo.org/doc/en/alsa-guide.xml#alsa-utilities
Alsa manages to find my card, installs itself saying it's all right. If I try to play a mp3 in Audacious, it starts to play, as if it were in fact sending the data to the audio board. I've already checked alsamixer for muted or low volumes. No problems like that. All kernel stuff was compiled to be loaded as modules. In /etc/modules.autoload.d/kernel 2.6 I have:
| Code: | snd_hda-intel
snd-mixer-oss
snd-pcm-oss
snd-seq-oss
|
loaded at boot. The alsa init script is also being loaded at boot. Alsa configuration was made with alsaconf.
Here is some useful data:
| Code: | # lspci -v | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
|
| Code: | cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf0d00000 irq 22
|
]
| Code: | # cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.14 (Fri Jul 20 09:12:58 2007 UTC).
|
| Code: | # cat /proc/asound/oss/sndstat
Sound Driver:3.8.1a-980706 (ALSA v1.0.14 emulation code)

I haven't got a single sound in linux! The computer is dual-boot, in Windows XP the sound is working fine. Any ideas on what I'm doing wrong? Thanks!

I had a lot of trouble making this work.
Here's what fixed it for me:
| Code: | | echo up > /proc/acpi/ibm/volume |
(Assuming you have the ibm acpi module thingy loaded, which is part of the kernel.)
Oh, and that assumes this is a thinkpad.

| Turn up all playback levels in alsamixer at the same time. The correct mixer in cards I've tried can be hard to guess. |

Thanks for the reply!
Unfortunately I don't have this ibm module nor anything similar in that directory. Well let's keep trying! |

All levels are at maximum. None of them is muted. Is there anything "special" besides this, that I should try?
Thanks! |

| Cheat a bit. Download a small live distro like Slax 6 and see if/how it gets sound. |

I've finally found the solution. I'm posting it so that others can perhaps benefit from it.
This audio card is supported only by a very new version of alsa, that comes with the (at the moment) unstable kernel 2.6.24.
If one emerges gentoo-sources/kernel-2.6.24-r3 or newer, the card will work out of the box.
On previous kernels the card is not supported. However alsa detects it as previously mentioned, thus making the user confused.
Well let the mp3s play!!  |

| If you use kernel <2.6.24 you can emerge >=media-sound/alsa-driver-1.0.15 which supports ALC268 as well ... |
