Sound card not working

asprakash · 09-26-2007, 04:29 AM

In my acer laptop, I have installed FC6. My sound card is not working.

My laptop configuration is, AMD Athlon 64 bit, nvidia Geforce 7000 series inbuilt network and sound card. I downloaded the driver from nvidia portal. The network and graphics card is working fine. But sound card is not working. Early I installed ALSA, OSS and xmms player with mp3 plug-in. When I played a mp3 song, the software is playing wel; but I cant get any sound. Even, i tested the sound detection option. It has detected the hardware. But not giving any sound.

Help me to solve this problem.

Several problems possible, you will have to investigate

1: sound card not configured, or muted.
Run alsaconf as root (in a terminal window) to verify that it is set up properly

2: Sound Muted
Run alsamixer as a user (in a terminal window) to verify that sound is turned up and not muted (or you can use the gui tool)

3: Programs are not set to use the correct sound device
Dig threw program options to find what sound device they are using, change if nessesary

4: Another program is blocking access to the sound card
Process of elimination to find offending program, then change its config to make it play nice

Thank for your reply.
@Kahless: Ya.I checked all the factors. But still the same problem.
I have installed latest open suse 10.3 beta, Ubuntu gutsy Beta and F7. Open suse and Ubuntu detected the h/w when i installed the OS. But the sound is not working. F7 cant able to find the h/w.
@DiBosco: In ubuntu it says,
0 [NVidia] : HDA-Intel - HDA NVidia
HDA NVidia at 0xf448000 irq 18

When i checked with alsamixer, the card type ::HDA NVidia
Chip ;Realtek ID 268

In Open suse:
0 [NVidia] : HDA-Intel - HDA NVidia
HDA NVidia at 0xf448000 irq 17
In alsamixer, card type:HDA NVIDIA
Chip: Realtek ALC268

Have a look here:

http://forum.mandriva.com/viewtopic....69074&start=25

Check my post about half way down where I say I have had some success.

It's probably worth trying this first:

Quote:

For us you need to mod the /etc/modprobe.d/sound file by adding at the bottom:

options snd-hda-intel model=toshiba index=0

By us I meant Mandriva users. Ubuntu users have a slightly different format. I don't know where Suse forked from and therefore where your file would be.

If that doesn't work alone, then try the newer Alsa drivers.

Good luck.

Aft 3 weeks back, I solved my sound card problem.Here i have mentioned the steps, what i had followed from OS itself.

* Installed Ubuntu Gutsy version for 64 bit
* login in console mode
* By default, the nvidia driver installed. Install the driver by using
$apt-get install nivida-glx-new
$sudo nvidia-glx-config enable
Then retsart the Laptop. Now almost the video problem will solved.

* Updated the packages.[kernel also updated.Really I dont know, whether its necessory or not. Simply I updated the latest kernel]
* Installed build-essential from package manager. It has resolved lot of dep problems.
* Downloaded alsa-driver-1.0.15rc3.tar.bz2
* Untar it
* $./configure
* $make
* $make install
* sudo vim /etc/modprobe.d/alsa-base
added this "options snd-hda-intel model=acer" in almost last line. Aft that save it.
* Reboot
* Now my lapy logged in with nice Ubuntu sound. Now the sound card working fine.
But FYI, still some bugs r there in this driver. Hope v can a stable driver soon..
Thanks to ALSA and Ubuntu....

I had a similar problem on my Gateway MX3228 with Debian Etch, or really with Linux in general. The way I fixed this problem was by going under /usr/src to see if there is a directory called Linux or Linux2.xxxxx . If there is a directory I suggest getting the latest build of alsa and compiling it from the source code, if there is not I built a custom kernel, which one would put in /usr/src/linux2.xxxxxx and then compiling alsa into that directory so it would look something like this:
yourname@yourcomputer`$cd /usr/src ; ls
alsa linux-2.6.23.tar.bz2
config-2.6.18-5-686 linux-image-2.6.23new1_2.6.23-10.00.Custom_i386.deb
linux-2.6.23

If there is nothing in here that says linux I would compile myself a kernel, if there is just compile the newest alsa build to here. There is a guide on compiling alsa right here http://www.alsa-project.org/main/ind...odule-intel8x0
just ignore the intel8x0 bit

Edit You can get the latest alsa build at http://www.alsa-project.org
