 Posted: Fri Dec 01, 2006 4:01 pm Post subject: I'm unable to get alsa working following alsa guide [solved] |
 |
|
Hi,
I have a Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)
(as seen with dmesg) and I'm trying to get it to play some sound.
I'm following the alsa guide so, once detected the driver I need (via82xx) I compiled in as a module in the kernel and run alsaconf
After detecting my soundcard and selecting it the process continues and exits de "blue screen" and then there is a lot of text scrolling down.
This text:
| Code: |

Finally the screen is cleaned and the usual "all is ok" notice appears
| Code: | ====
Now ALSA is ready to use.
For adjustment of volumes, use your favorite mixer.
Have a lot of fun!
|
Unfortunately if I run alsamixer I get this:
| Code: | | alsamixer: function snd_ctl_open failed for default: No such device |
Of course I don't have snd_ctl_open it failed just before.
I've also tried to build the drivers in the kernel, instead of building them as a modules and the output is the same.
My conf file can be found here.
lsmod returns:
| Code: | Module Size Used by
snd_ac97_bus 6656 0
snd_page_alloc 12432 0
fglrx 465012 8 |
but right now I have the sound modules built in in the kernel, so I think this doesn't matter.
my kernel is 2.6.17-gentoo-r8 and the architecture is AMD64.
If there's any information that can help i'll be happy to provide it.
I'm sure I'm missing some silly point... or forgetting to do something basic... but I can't see what. I've searched for errors like mine but I wasn't able to found anything that answered my question...
If anyone can lend me a hand I'll be very grateful.
Thanks!

try this for /etc/modules.d/alsa
| Code: | alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd cards_limit=1 |
then make sure that /etc/make.conf includes
| Code: |
ALSA_CARDS="via82xx"
|
rebuild alsa-utils and confirm that your kernel has
| Quote: | ~ # cat /usr/src/linux/.config|grep CONFIG_SND_VIA82XX
CONFIG_SND_VIA82XX=m |

First of all, thanks for your answer dcoats I followed your recomendations but I still cant make it work.
I recompiled my kernel with the drivers for the soundcard as modules.
Now my config is this:
/etc/modules.d/alsa
| Code: | alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.13 ---
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx
# --- END: Generated by ALSACONF, do not edit. ---
|
my make.conf file has ALSA_CARDS="via82xx"
and cat /usr/src/linux/.config|grep CONFIG_SND_VIA82XX returns:
CONFIG_SND_VIA82XX=m
# CONFIG_SND_VIA82XX_MODEM is not set
I reemerged alsa-utils
The odd thing is that now, when I run alsaconf I get this:
www.telmun.net/screenshot.jpg
I get the same errors than before trying to configure any of the "two" cards.
I'm stuck there :\

| alsaconf is not always correct, It creates/writes /etc/modules.d/alsa so try the /etc/modules.d/alsa i pasted you and rc-update add alsasound default then reboot see if everything finds itself correct... |

the /etc/modules.d/alsa I pasted is the modified version, by default alsaconf created just this:
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.13 ---
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-via82xx
# --- END: Generated by ALSACONF, do not edit. ---
after running alsacfg i added the lines that you suggested and tried again, it didn't work :\

does alsasound start?
/etc/init.d/alsasound restart |

according to http://www.telmun.net/config you have them built into the kernel and not as modules......
CONFIG_SND_VIA82XX=y
CONFIG_SND_MPU401_UART=y
CONFIG_SND_AC97_CODEC=y
CONFIG_SND_AC97_BUS=y
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_RAWMIDI=y
CONFIG_SND_SEQUENCER=y
CONFIG_SND_SEQ_DUMMY=y
CONFIG_SOUND=y
try them as m |

yes, that was the configuration prior to recompiling them as modules
EDIT: I've just actualized the file (www.telmun.net/config) to the current one.
if I try to restart alsa that's what i get.

And alsa gets started but whenever I try to play any sound it pops out errors.
Edit:
this seems strange to me also:
| Code: | # modprobe via82xx
FATAL: Module via82xx not found. |

| Code: | | rm -rf /lib/modules/$(uname -r)/alsa-driver |
This is all in the gentoo alsa guide...
http://www.gentoo.org/doc/en/alsa-guide.xml
"The above issue is caused when you switch from alsa-driver to in-kernel ALSA because when you unmerge alsa-driver the module files are config protected and hence get left behind. So, when you switch to in-kernel drivers, running modprobe gives you a mix of alsa-driver and in-kernel modules thus causing the above errors." |

OMG.
It's working.
I'm sorry.... I never reached the section "problems and issues".
Now I feel bad for wasting your time!
Sorry.... And a ton of thanks... I'm putting the solved in the first message and learning to read all of the guides.
