 Posted: Mon Jan 20, 2003 9:15 pm Post subject: sound probs with alsa ?? |
 |
|
I installed gentoo, at the moment I'm trying to configure my sound with alsa. I read the manual and did the necessary steps. But with aplay .....wav I get nothing. But I don't know where the problem could be:
- Kernel/Sound:
Sound card support as module, rest no
kernel 2.4.20 gentoo sources
- my onboard soundcard:
C-Media CMI8738 -> snd-cmipci
- my /etc/modules.d/alsa ALSA portion
| Quote: |
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
alias snd-card-0 snd-cmipci
alias snd-card-1 snd-cmipci
alias snd-card-2 snd-cmipci
alias snd-card-3 snd-cmipci
alias snd-card-4 snd-cmipci
alias snd-card-5 snd-cmipci
alias snd-card-6 snd-cmipci
alias snd-card-7 snd-cmipci

Any help would be appreciated. I don't know where to look for the error. Thx. |

emerge alsa-utils
then use alsamixer, its a console style gui for the amixer program. You need to have Master and PCM both unmuted and turned up in order for sound to be produced.

I followed the manual and did the steps you mentioned. Doing this I got the following error:
SPAWN root # amixer set Master 100 unmute
amixer: Unknown playback setup 'unmute'..
My hardware is okay, using Suse 8.1 2.4.19 sound is fine. |

alsamixer, not amixer. Amixer is the hard way to do it :p
alsamixer is a console gui for amixer and is a bit easier to use.

I just checked the .config of the 2.4.19-Suse Kernel. I found:
| Quote: |
#
# Advanced Linux Sound Architecture
#
CONFIG_SND=m
CONFIG_SND_SEQUENCER=m
CONFIG_SND_SEQ_DUMMY=m
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_VERBOSE_PRINTK=y
CONFIG_SND_DEBUG=y
CONFIG_SND_DEBUG_MEMORY=y
# CONFIG_SND_DEBUG_DETECT is not set
|
I checked the .config of the 2.4.20 gentoo kernel and didn't find these entries. Where can I find the alsa options  |

Okay, it works now. Here's what I did
emerge unmerge the alsa stuff
rm modules.d/alsa
Repeated every step, now it works - don't know what the problem was.
Anyway thx for the help. |

be aware that the newest alsa does not use the snd_ prefix in the config anymore.
I was at first a bit stumped when I updated /re-emerged alsa and my soundcard wasn't found anymore.
I followed the alsa install guide from the user docs.
http://www.gentoo.org/doc/en/alsa-guide.xml
Now this is how /etc/modules.d/alsa should look like :
| Quote: |
# ALSA portion
alias char-major-116 snd
options snd major=116 cards_limit=1
# OSS/Free portion
alias char-major-14 soundcore
|
And this is wrong in the guide if you are using
| Quote: |
* media-sound/alsa-driver
Latest version available: 0.9.0_rc6
|
| Quote: |
# ALSA portion
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
# OSS/Free portion
alias char-major-14 soundcore
|
Just erase the snd_ prefix and everything works again  |
