Intel HDA - no sound

[AeroIllini]

Ok, I've been all over the forums and the web in general, and I'm stumped.

I have the following Intel HDA audio card:

Code: Select all

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

I have media-sound/alsa-driver-1.0.14 installed (although I have also tried all this with stable media-sound/alsa-driver-1.0.14-rc2-r1 with the same results -- I have also tried built-in drivers and kernel modules, to no avail). The computer is a Toshiba Tecra A8 laptop. Alsamixer shows the chipset as Realtek ALC262.

/etc/init.d/alsasound starts with no problems. alsamixer shows all the correct channels, which are unmuted with volume at reasonable levels. But still, I get no sound... not out of the speakers, not out of the headphones. The only sound I hear right now is my head against the desk.

What can I possibly be missing?

[PaulBredbury]

Your /etc/modules.d/alsa is incomplete - look at the top - "alsa portition, oss portion" - but there's nothing there.

Anyway, follow wiki article carefully, to reduce the number of silly mistakes made.

[LiquidAcid]

Nonsense, his /etc/modules.d/alsa is completly alright. I have nearly the same file, only with even fewer entries (removed the OSS part completly). The problem has to be somewhere else.

[PaulBredbury]

It should be:

Code: Select all

# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore

[LiquidAcid]

Code: Select all

 cat /etc/modules.d/alsa

Works perfectly one more than five machines.

[AeroIllini]

I tried PaulBredbury's solution of adding the alias lines to /etc/modules.d/alsa, but nothing changed.

I have been through all the wikis and all the howtos. Everything seems to work just fine: the modules load without error, dmesg indicates successful loading, alsamixer gives me proper channels which are unmuted and volume up'd, and when I play sound through programs such as aplay or xmms, they play without error as if the device exists. My /dev/dsp device exists, and writing /dev/random to it works without error.

But still there is no sound.

My guess at this stage would be that this is due to the complexity and intricacies of the snd-hda-intel driver itself. Looking through /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt, I see that there are lots of different sound cards and boards that all use the same driver, and it's possible that I don't have the right parameters passed to the module. Also, I think maybe the modem is on the same chipset, and perhaps that is interfering with operation of the sound card, but I don't know how to turn it off (there's no option in the BIOS dealing with the modem).

But keep the ideas coming, and I'll try 'em all.

(Note: this is not a hardware problem. I still have the factory-installed WinXP partition, and sound works just fine on that side of the dual boot.)

[Cyker]

Are you using the built-in kernel driver?

If so, dump it - Gentoo's main stable kernel is very out of date and lots of newer hda devices do not work with it.

You're much better off removing all the ALSA stuff from the kernel and emerging the "alsa-drivers" package which is much more up to date.

You need to remove all the bits of ALSA from the kernel before it'll let you install it 'tho, and that can be a bit of a chore.

Try to also undo any ineffectual config file changes you made as well, because weird crap can happen when settings the alsa-driver install makes trip over ones you've made - They can be irritatingly difficult to track down.

[AeroIllini]

I'm not using the in-kernel driver, although I did try it.

I'm running alsa-driver-1.0.14 unstable, and I have also tried alsa-driver-1.0.14-rc2-r1 stable.

Is there a list somewhere of all the config files I need to check? I could just delete them all, unmerge all ALSA packages, and start configuring from scratch again.

[LiquidAcid]

Have you taken a look in the alsa bugzilla if there is a (detection?) problem with your card? I've also a HDA intel chip and had massive trouble when I installed gentoo on my dell laptop. After some time things were fixed. They problem are the different types of HDAs that come out every month.

You could also try to enabled debugging on alsa-driver and see if that gives you some more information.

[Dirk.R.Gently]

To fix my HDA intel i followed pauls wiki to remove the kernel alsa driver. Then I removed alsa from the kernel .config and recompiled the kernel. Then remove .asoundrc ( it can mess things up if configured incorrecly , most times you won't even need it ). Installed the alsa driver and let alsaconf configure it. Alsaconf seems to work fine with the HDA intel card. If you still have troubles look at the bottom of that wiki and read the section on adding options to modules... that might do it.

[AeroIllini]

I am using the alsa-driver option.

I deleted all the module binaries in /lib/module/alsa-driver, and remerged alsa-driver with USE="debug". Then I added the following line to /etc/modules.d/alsa:

Code: Select all

options snd-hda-intel model=auto

and I see the following in dmesg:

I also got this message from /etc/init.d/alsasound start:

PaulBredbury,

I have tried that. I added 'enable=1 index=0 model=basic', ran 'update-modules', and reloaded alsasound. I adjusted levels and mutes in alsamixer. Still no sound.

[LiquidAcid]

Have you headphone plugs? Try using them and check if you've sound there.
You could also try to hook up a mic (if you have one) to the mic plug (if you have one *g*) and see if you can record something.

The best thing would be to get in touch with tiwai, who is responsible for the hda part of alsa. Simply write a bug report on alsa with all the infos you gave us. I think he will know what to do.

[AeroIllini]

I've tried headphones before. No dice.

Just now, I tried recording something with the command:

Code: Select all

arecord -f cd -t raw | lame -x - out.mp3

Then I copied the mp3 file to my desktop and tried to play it. There was sound, what I recorded, but the volume levels were really low, even though I cranked all the capture volume levels up high in alsamixer. So mic works, sort of.

[LiquidAcid]

Have you tried playing some very loud file (like some 0dB sinus tone) and cranking up all volume controls to the max?

I know there were some problems related to playback volume. The volume when the controls were maxed out was much lower than with maxed out controls in Windows. So there was some kind of (hidden?) switch in the codec to activate some pre-amplification.

Could you at least *try* to be a little less condescending?

[AeroIllini]

Worth a shot.

What's the best program to create such a tone?

[LiquidAcid]

I think Audacity can do this.

EDIT:
OK Audacity seems to be a bit of an overkill. sox can also synth sine tones.

[AeroIllini]

Ok, I created a 1 second sine wave tone at 440Hz in sox. I was able to play it no problem on my desktop, but even with volume cranked way up on the laptop, I got nothing.

I've posted to the ALSA bugtracker, #3265. We'll see what they say.

I also have a Toshiba laptop with an intel-hda chip. The trick has always been the /etc/modules.d/alsa file:

Code: Select all

##  ALSA portion
##  OSS/Free portion

# OSS/Free portion - card #1

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 1.0.14rc2 ---
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---
options snd-hda-intel model=3stack

The last line is the key line to get it working.

Edit: Don't forget to run "update-modules" and restart the driver (or reboot completely).

[AeroIllini]

I already tried the 3stack model option. Thanks for the idea though, keep 'em coming.

[mkk]

Even so, keep the 3stack option. I can almost guarantee you that the final solution will require it. I also get what look like reasonable input/output controls when using other options like auto, basic, and toshiba, but 3stack is the only one that actually works.

[mkk]

Also, could you humor me and print the output of lspci? I want to see if you have the same model number as I do.

[LiquidAcid]

I think he has already posted lspci output, see first post.
