No sound from RealTek audio card? [Solved]

khalderon · 2008-01-18 13:08:25

I can't hear any sound from my laptop. This is what I executed:

pacman -S alsa-utils
gpasswd -a yourusername audio
alsamixer
aplay /usr/share/sounds/alsa/Front_Center.wav
alsactl store
nano /etc/rc.conf
DAEMONS=(syslog-ng network crond alsa)

I checked alsamixer once more:
headphones mm
PCM 75<>75 (tried even 100, which means gain = 0)
Front 75<>75 00 (which means unmuted)

No effect.
Then I issued
lsmod | grep '^sound'
which gave only:
soundcore 6496 1 snd

ls -l /dev/snd/
gave usual results like controlC0, pcmC0D0p etc.
What to do then?

Make sure to un-mute all channels. I noticed that some times muting PIM also mutes Main (even if it is at 100%), and try again.

You only need to do:
# pacman -S alsa-utils
# alsaconf
add alsa to modules in rc.conf

Everything else is taken care of by the alsaconf-script (like loading the necesary modules for your soundcard, which might be the problem with your install)

Nope. Even alsaconf didn't help me. It detected 2 devices - the HDA Intel and a legacy one. Since the legacy one was not recommended, I chose the first one.
I checked the alsamixer several times - no effect.
Could it be that under Vista I use a driver from RealTek High Definition Audio Driver?

khalderon · 2008-01-18 17:47:38

Just to give you more information, there is the output of amixer:

khalderon · 2008-01-18 17:52:28

Since I downloaded the drivers from the RealTek website, I noticed there are also drivers for Linux:
http://www.realtek.com.tw/downloads/dow … Down=false

Does someone know whether and how this will work?

khalderon · 2008-01-19 09:13:03

The drivers fail to install.
I post the output of 3 commands issued, as the wiki suggests:

http://nopaste.php-q.net/14947
http://nopaste.php-q.net/14948
http://nopaste.php-q.net/14949

I tried everything I could with no effect. My Arch system will remain silent. A huge downside of it.

click on the last link u posted, all the channels are set to zero, That means they are MUTED!

khalderon · 2008-01-19 14:56:45

But how do I unmute them?

ralvez · 2008-01-19 15:57:34

Use the arrows up and arrow down in the keypad to increase or decrease the volume in alsamixer.

R

khalderon · 2008-01-19 16:02:04

I have done this several times with no effect. Headphones, PCM, Front, Mic front and Mic boost are near max and still no sound at all.

ralvez · 2008-01-19 16:13:10

Well ... I do not know what to say.
This is what I do in all my setups and always works, take a look; perhaps you skipped some step?

0. make sure you add yourself to the audio group
1. insall alsa (pacman -S alsa-lib alsa-oss alsa-utils alsaplayer gstreamer0.10-alsa alsa-plugins )
2. run "alsaconf" to detect and configure your audio card.
3. at a console type: alsamixer --> use it to adjust volume (to start make everything at lest 60%)
4. aplay /usr/share/sounds/alsa/Front_Center.wav --> Test that sound works
5. issue "alsactl store" --> Save Settings (as root)
6. add alsa to the daemons line (/etc/rc.conf)

Hope this helps.

khalderon · 2008-01-19 18:02:29

I don't see a real reason why would I download that many packages (+11 MB)?
It doesn't help. I am sick of repeating one and the same thing over and over again. I'd better go for installing X and a DE.

ralvez · 2008-01-19 18:05:37

Suit yourself

synorgy · 2008-01-20 00:59:23

If I understand you correctly, you have installed all required alsa packages and tried to configure. What doesn't work is attempting to push up the volume via alsamixer/aumix etc., unmuting also does not work.

Am I correct?

If so, you may have a similar issue to what happened to me a ways back. Is your current kernel up to date? The problem I had involved the fact that my sound card (though it was extremely common and, well, sh*tty) was affected by a feature regression in the ALSA code and an incompatibility with kernel in what was then [current]. I had to wait for the kernel to catch up to ALSA to do anything, but the regression had to be fixed before I could do anything useful.

Moral of the story (also known as the 'tl;dr' or 'too long; didn't read' version) - Try updating your kernel if all else has failed. If nothing useful comes out of that, try searching the ALSA site.

khalderon · 2008-01-20 06:44:23

You are partially correct. I use alsamixer to raise up the volume. There I see these bars: Headphones, PCM, Front, Front Mic, Mic Boost. Only Headphones and Front could be unmuted (mm->00). I tried everything to be max (gain = 0). No sound.
I've updated via pacman -Syu several times. No change.

jacko · 2008-01-20 07:39:23

try pacman -Syyu instead to force the database sync. I had a weird problem one time when the database would not sync therefor what I thought was a current up to date system was an out of date one.

Its all u got left to try at this point, see what happens.

khalderon · 2008-04-22 06:15:05

Nope. After a few months I did try it again. The same problem. Arch hasn't moved forward. It just doesn't want to work on my absolute simple laptop

khalderon · 2008-04-22 08:32:21

I got it! I had to edit /etc/modprobe.conf and add "options intel-snd model=acer" or something like that! Now it works flawlessly! I wonder only why no one pointed me to this simple solution???

synthead · 2008-04-22 08:52:17

Nice going Don't forget to mark this thread [solved]. The next user the encounters the same problem can use this thread as a reference.

Perhaps because you never mentioned, until now, that you have an Acer laptop
They seem to have that problem, mine did.

khalderon · 2008-04-22 12:37:44

Yeah, we all made a few mistakes. Now it is time to go forward...
