 Posted: Wed Jun 18, 2008 11:42 pm Post subject: Cannot get sound to work |
 |
|
lspci | grep -i audio
gives the following:
| Code: |
Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) |
This is the board I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131096
and the specification states:
| Quote: | Onboard Audio
Audio Chipset C-Media Superior Quality Audio 7.1 channel CODEC (Vista ready)
Audio Channels 8 Channels |
Now I've seen C-Media in the menuconfig and re-built the kernel and tried it out to no avail. I have also emerged alsa, all the gstreamer codecs, ffmpeg, lame, etc.. yet nothing will play audio. All my videos play without audio, no music will begin to play at all. alsamixer will not start, mpg123 (stating ALSA lib cannot find card '0') won't play a thing. gnome-volume-manager will not open (no error message). |

According to this message, nVidia HD audio chipset support can be found in the snd-hda-intel audio driver.
Device Drivers ->
Sound ->
ALSA ->
PCI Devices ->
Intel HD Audio [*] or [M]
This will get your sound going  |

| hmm, that didn't seem to work either. alsaconf is not able to find any PnP or PCI cards. |

Do exactly this:
1. Compile snd-hda-intel in to your kernel. [*] instead of [M]
2. Reboot off this new kernel if necessary.
3. Edit /etc/modules.d/alsa and change
alias snd-card-0 snd-**********
to
alias snd-card-0 snd-hda-intel
4. Start alsasoudn with /etc/init.d/alsasound start
5. Run alsamixer, or aplay -l to see if the sound card is working
6. Report any errors you might encounter
snd-hda-intel is definitely the proper driver. If this doesn't work then I've no clue what to do. |

If that doesn't work, compile it as M.
Blessed be!

Hmm.. mpg123 isn't kicking error messages any longer aplay -l gives the following:
| Code: |
$ aplay -l

Still not finding the on-board card though.
Just in case here's my alsa module

Okay, compile snd-hda-intel as [M], sorry for the oversight.

You have two cards in your system? Add your other card to /etc/modules.d/alsa as snd-card-1 in the same way you added snd-card-0. |
