hda-intel fine & no sound

[braulio]

Hi, before anything thanks for your help each time i had trouble with my old box. I'm from argentina and now i'm installing gentoo on an amd64 box, motherboard M2N-X and everything works fine but i have no sound. I did read a lot of post here but none of them helped me.
I had follow the Gentoo Linux ALSA Guide but had no positive results.

here is the info i think you should find usefull.

Hi,

the necessary modules seem to load. This is basically good. I assume that you also executed alsaconf as root to setup the soundcard and the /etc/init.d/alsasound script and altered the volumes for the channels with alsamixer or kmix or whatever.
What happens when you do as root "/etc/init.d/alsasound restart"? Any errors or does the alsaservice just restarts normally?
Do you have no sound in kde or in vlc or audacious where you can choose which sound output you want to use (alsa, jack, oss)?
Please also make a file in your home directory and name it ".asoundrc". Put this into the .asoundrc file.

Code: Select all

pcm.card0 {
    type hw
    card 0
}
ctl.card0 {
    type hw
    card 0
}

Afterwards check if the file has executable access. Otherwise do "chmod ug+rwx ~/.asoundrc" and restart the /etc/init.d/alsasound.

Just to check some basic things before getting more into troubleshooting and trying to recompile and all that stuff. I read a lot of threads with those nvidia sound chips and problems getting them to work. =0)

Hello. Your assupmtion is right, i did run alsaconf and had found hda-intel card, i also get this msg:

i set de volumes with alsamixer but nothing happend.
when i restart alsasound script get this:

i created the file but no results

[eracks]

I had this issue with my laptop, and solved it rather easily by passing the model= option to the snd_hda_intel module. Do a dmesg. If you see the snd_hda_intel complaining about an unknown device, edit /etc/modules.d/alsa and add the following line:

options snd_hda_intel model=<your model here>

I'm not sure what models are available, but I was able to make it work with the 'toshiba' model, even though I'm not actually using a Toshiba laptop. You could try the same (though there may be one better suited for your specific machine.)

Let us know if this helps

James

[your_WooDness]

ah...yes, i can remember that this also was an issue when i read about those sound problems. You can find the available models in the file /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt and search for ALC883 or just 883.
Unfortunately I haven't found any helpful hints in google so I guess you will have to trail 'n' error, except for someone knows which model to insert. =0/

Thanks for the help, i already tried that one but didn't work. Do i have to include something particular in the make.conf? Do i have to install the alsa drivers instead of include them in the kernel?

[d2_racing]

Why use the alsa-driver package when you can use the built in kernel driver.

We miss something...it's not a big deal a think...

Come on guys, we need to figure this out

[OmSai]

Why use the alsa-driver package when you can use the built in kernel driver.

Definitely.

Except it seems the nVidia hda-intel integrated cards series, new as they are, have kernel support after 2.6.22-r8 (since my MCP51 didn't work with that version)

[braulio]

Thanks all of you for this solutions. I really appreciate this. I could solve the problem upgrading to the latest kernel 2.6.23-r3. Now i have sound.

PD: sorry i didn't post before but couldn't solved till now. Thanks

[PhilD]

Hey guys, hope you don't mind me tagging on the thread here. I have a similar issue. Although mine has been working for the past year prior to some updates a while back. I have been gone for a while so I am not sure exactly when it broke, just that it did. I have ran the alsa info script and all information is up at:

http://pastebin.ca/871167

I have noticed that Dmesg gives the following error:

Code: Select all

hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...

I have tried all version of the option snd_hda_intel module in my modules.d/alsa file with no change. I must say, it is rather frustrating when something that has been working great breaks with an update.

Thanks for any and all help!

I'm using the same MCP51, as you, and also alsa-drivers instead of kernel sound.

If your sound broke with the update check your config files, maybe they got accidentally overwritten -

(Might be a little different depending on your motherboard...)

Code: Select all

# Alsa kernel modules' configuration file.
##
## 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.

##  OSS/Free portion
alias sound-slot-0 snd-card-0

# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-12 snd-pcm-oss

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.15rc1 ---
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---

and of course make sure you have the line -

Code: Select all

ALSA_CARDS="hda-intel"

If it wasn't there you have to re-emerge alsa-driver

If you updated your kernel, follow the Gentoo ALSA guide and make sure the configuration is what it should be.
Also, run alsaconf to see if ALSA can see your sound. You could probably just go through the whole setup, using the guide (above).

[PhilD]

As expected it is just my system.

I wasn't running the alsa-driver package, but switched to in during my attempts to fix the problem. I should have mentioned that. That is the current state on my box though. Our /etc/modules.d/alsa files match exactly as luck would have it. I have also ran through the Gento ALSA Guide to make sure I haven't missed something. When done by the book everything says it is happy but no sound, and that single hint in dmesg.

I use alsaconf to configure the card and no errors or warnings are generated. I did have a problem a few months ago that the card would quit working and I would have to rerun alsaconf. But it would always come right back.

Thanks for the suggestions! I worked through them all.... Any others?

PhilD

[OmSai]

I did have a problem a few months ago that the card would quit working and I would have to rerun alsaconf. But it would always come right back.

I would guess then that your hardware is faulting
But let's rule out everything else before going there...

First off all, to rule out external hardware, use a working pair of headphones (for example) instead whatever speakers you were using previously.

Then check if you can see the moving sound meter when you run:

Code: Select all

aplay -vv /usr/share/sounds/alsa/Front_Center.wav

You can also try to play a sine wave tone with

Code: Select all

speaker-test -t sine

If all is well with those commands but still no sound, check into your alsamixer settings.
Unmute all, turn up the volume to say 80% and also set output to 2ch
I had an issue where my XFCE volume control would sometimes kill my sound.
I finally found out that just opening the xfce-mixer gui in my taskbar somehow switched my card over to 4ch output (but still displayed 2ch?!? on the gui)
I work around that by resetting it to 2ch using alsamixer.

Another idea, though you've probably tried this already, is to look at the unofficial ALSA troubleshooting guide

[PhilD]

Well, a quick update. I did finally get it to work again with the 6stack-dig model, a lot of rebooting, and probably some luck to go along with it. I am not sure why it quit working in the first place, but hopefully now that the module is called out it will stay working.

I had tried the head-phones with no luck. I wasn't expecting it to work since I was getting a codec error in dmesg. I did a kernel update and some more playing with the /etc/modules.d/alsa options and finally got a load that would not produce errors when /etc/init.d/alsasound restart was issued. I had to add the 6stack-dig as well as the fix_position= 1 (I think that is correct). After a update-modules the correct position and model was loaded with a restart. My old mixer settings were also loaded in.

Like I said above, not exactly sure what did it, but hopefully the fix will last. Thanks for the help!!!!

=== All the above is when the loaded kernel is : linux-2.6.30-gentoo-r5 ===
And there I also posted a diagnose script here:
http://pastebin.ca/1629579

Also:
Something small but ugly must be in the way, because:
alsamixer -c 0 opens:
Card: Conexant CX8811
Chip: CX88
and:
alsamixer -c 1 opens:
Card: HDA ULI M5461
Chip: Realtek ALC882

while it is exacty the opposite when the working linux-2.6.29-gentoo-r2 kernel is loaded (alsamixer -c 0 opens ULI M5461 as it probably should, etc.). I did boots galore... to no avail to get the linux-2.6.30-gentoo-r5 (nor linux-2.6.31-gentoo-r3 for that matter) to work...

=== When kernel is : linux-2.6.29-gentoo-r2 ===

Audio works for programs, mplayer, audacios or any and KDE 4.3 is fine in all regards, for root and user. Adobe-flash in Firefox or Konqueror works...

Well, if I don't get quick fix from an obliging reader soon (but thanx anyway), I'll leave the linux-2.6.30-gentoo-r5 for now, and enjoy my Gentoo on linux-2.6.29-gentoo-r2 in my work and rare spare time...

This issue is clearly not purely Gentoo, but Gentoo-wise only on this thread I find closely similar problems (solved or not).

I also read:
/usr/src/linux/Documentation/sound/alsa/HD-Audio.txt
and associates.
I didn't find much even there for my case, as KDE 4.3.1 on linux-2.6.30-gentoo-r5 starts and ends nicely audibly (so the sound works...), but KDE won't let me use any audio programs...
Annoying...

in the top post via editing the .asoundrc or straight in the /etc/modprobe.d/alsa.conf didn't help any...
And in a rather unlikely place I seem to have found the solution.
But I don't have time now to tell you... Sorry!... I have other work on my hands.
You can send me email if you really can't work this out...
No, I'm only joking. I know occcasional Gentoo user will be reading this, because it's a dead end if you have abnormal drivers trying to make you pull your hair by grabbing card0 position and not letting you play anything out on your audio...
That's what they say you need to put in your
/etc/modprobe.d/alsa.conf
You can do this on your Gentoo:
echo "# Prevent abnormal drivers from grabbing index 0" >> /etc/modprobe.d/alsa.conf
echo "options cx88_alsa index=-2" >> /etc/modprobe.d/alsa.conf
Here is why:

That does seem to have prevented me from smashing things in my environment out of despair this evening
I hope this helps.
