alsa audio not working


Hello Again !

After burying my Linux external drive for years I want to start using my Linux again !

I have a lenovo laptop but can not start the audio, in my old desktop machine where I was using this harddrive before, I could easily start audio by restarting the sound driver ( can not recall, I guess I was using rcalsasound start ... or something like that)



detailed info is available at http://www.alsa-project.org/db/?f=14...ab2bd4fa18f1a3

Since your drive has been put away or buried updating your system would be top priority first-

I'm not the sound expert but when I applied these stratigies in the terminal I had sound.

There is a WARNING for Alsa and your distro-
When updating ALSA, it is important that you ensure to install the ALSA drivers that are specific to your kernel version only. This Alsa-update for OpenSUSE should be helpful:

http://en.opensuse.org/SDB:Alsa-upda...kernel_version

Also looking at the link that you posted you have Pulse Audio installed but it is not running-
If it were me I would ensure that only one kind of Sound Application is in performance otherwise your distro or will undergo conflicting issue's.

If you still don't have sound try:
Open the mixer and raise up the pcm and the master.
Try running:
Code:
alsa+1 init
And add yourself to the audio group; log out and log back in.
Code:
adduser yourname audio
Open the terminal and type:
Code:
alsamixer
See a black/grey background with multiple column. Raise all columns all the way up, mute and un-mute each column. Do a sound test which is file noise.wav
{00} means un-mouted and {mm} means muted at the bottom of each colums-

The file to check on and make sure it's ok would be your
/etc/init.d/alsa-utils and the /usr/share/sounds/al

Here's the main page to your distro for additional help. The current version of your distro looks like 12.2
http://www.opensuse.org/en/
http://en.opensuse.org/Features#open...nd_Easy_Manner

Depending on which Lenovo you have you can run:
Quote:
lspci | grep -i audio
To find out which sound card you have and look for a driver if you deem it necessary-

Hope this helps;aarsh
