 Posted: Thu Jan 04, 2007 4:54 pm Post subject: Trouble installing and initializing alsa. |
 |
|
I having trouble installing and initializing alsa. I compiled my kernel with alsa support built in. I edited the alsa modules file correctly and the alsa mixer says the volume is at 90%.
The only sound I can get however is the bell beeper on my motherboard.
My question is do I need to load the sound module (snd_emu1k01) with: /etc/modules.autoload.d/kernel-2.6 ?
If not what have I missed to get my sound working? |

Hmm I was getting trouble with mine, but it was because I was trying to do both.
Your building alsa into the kernel so you can't use the module... try using the module.
http://www.gentoo.org/doc/en/alsa-guide.xml
Good luck, not sure it's helpful or not... helped me

Using alsa provided with the kernel is more stable IMHO.
Enable alsa option in the kernel (choose yes).
Enable all other options under sound as modules.
Disable OSS.
You may enable ALSA OSS emulation.
enable support in the kernel for auto-loading modules.
reboot.
issue the command: lsmod
are snd modules listed.
issue the command:
/etc/init.d/alsasound start
post the error you get.
also post the last few lines that are output from dmesg. |

This is stupid, I know, but I have to ask cuz I forgot to do it a few weeks ago myself. Did you make sure to add your user to the audio group? I'm not trying to insult your intelligence, but even after more than a year of installing Gentoo on various systems, I wasted 3+ hours troubleshooting my audio because I forgot to do that.

If it's built in to the kernel like mine is why would you need to load the module? |

You could test your alsa using command | Code: | | cat /dev/urandom > /dev/dsp |

I'm not getting an error. In fact I just found out that my headset which plugs in via usb is playing sound but my regualr speakers connected via my Audigy ZS2 card is not playing sound.
I guess I should mention that the card plays fine under SuSE and Fedora.... so I'm guessing with all this going on that it's some kind of configuration error.
Here is the output:
Station-LV426 tylerm # /etc/init.d/alsasound restart

And what about | Code: | | cat /dev/urandom > /dev/dsp |
?
Did you hear some noise? If yes, your problem is probably desktop or sound application related. You can use command aswell. |

I did not hear any noise.
\the output from speafer-test looks ok but no sound:

My last suggestion. Could you reboot and not start X-session? After that make sure that alsamixer is unmuted ( Master and PCM ) and run speaker-test ?
I am realy curious. |

Same thing. Alsa does find the usb headset. All sound is playing fine out of it. (DVD's, mp3's...etc)
Is there an eslect operation that can choose the alsa output? |
