Acer 4530: Sound lost after updating OpenSUSE from 11.2 to 11.3

Hello all.

I am currently running OpenSUSE 11.3 x86_64 on an Acer Aspire 4530 laptop. A few weeks ago, I updated OpenSUSE from v11.2. After the update, no sound comes out from the laptop (for any events such as system notifications, media playback on Amarok/ SMPlayer, etc).

Running “/usr/sbin/alsa-info.sh” gives the following output:
http://www.alsa-project.org/db/?f=4d051161c2b3ca2f1d382a7b85a7c373cd690fb6

Invoking “rpm -qa ‘alsa’” outputs the following:

alsa-utils-1.0.23-1.8.x86_64
alsa-oss-1.0.17-29.2.x86_64
alsa-plugins-1.0.23-1.9.x86_64

alsa-plugins-pulse-1.0.23-1.9.x86_64
alsa-plugins-32bit-1.0.23-1.9.x86_64

Invoking “rpm -qa ‘pulse’” gives the following:

libpulse0-0.9.21-10.1.1.x86_64

pulseaudio-0.9.21-10.1.1.x86_64
libxine1-pulse-1.1.19-1.pm.44.3.x86_64

Invoking "rpm -q libasound2 " gives:

libasound2-1.0.23-2.12.x86_64

Invoking “uname -a” gives:

Linux rep 2.6.34.7-0.3-desktop #1 SMP PREEMPT 2010-09-20 15:27:38 +0200 x86_64 x86_64 x86_64 GNU/Linux

Invoking “cat /etc/modprobe.d/50-sound.conf” gives:

options snd slots=snd-hda-intel
# M71A.L0dcPjIVUjB:MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio
alias snd-card-0 snd-hda-intel

Please help and thanks in advance.

As su -

Please try:

rcalsasound restart

Obviously check all the Mixer settings that it’s not muted.

Sometimes the ‘update’ as opposed to a clean install simply … does … not … work.

The diagnostic script output is clear. Your sound hardware is NOT identified by the alsa sound driver.

From my perspective, you have three choices:
(1) update your kernel from 2.6.34.7-0.3-desktop to 2.6.34.7-0.4-desktop where that latest version fixes some user’s sound problems, or
(2) update alsa per the guidance here: SDB:Alsa-update - openSUSE where you not only have to install alsa-driver-kmp-desktop but you also should update all of your other alsa apps, or
(3) install openSUSE-11.3 again, but this time do a CLEAN install and not an update.

Also, please be certain your sound is switched ON in your PC BIOS (if there is such a control).

@caf4926 and oldcpu
Thank you both for your quick replies. I was able to restore the audio back. :smiley: :smiley:
God speed!

Great
Usually it’s good, if you can, to say how or what helped. So others can read and perhaps benefit later.
