    First, let me WELCOME you to openSUSE Linux and to openSUSE forums.

    Further to what caf4926 posted, I recommend before you start deep into troubleshooting you read our "stickie" : NEWBIES - Suse-11.1 Pre-installation PLEASE READ - openSUSE Forums

    and also brush up on openSUSE concepts: Concepts - openSUSE ... the concepts are important. ... without a rough understanding of that, the reason why you are asked to do things will often be totally lost on you.

    Now the general advice I give for sound problems is to start trying to work your way through the openSUSE audio troubleshooting guide: SDB:AudioTroubleshooting - openSUSE which is what caf4926 noted.

    Do NOT use the startup system sound as your criteria for stating sound does not work. Also be certain to check your mixer. Its not uncommon for a mixer setting (master, pcm or speaker) to be muted upon boot. In KDE your mixer is "kmix" (the small speaker in right hand corner). In Gnome your mixer is "alsamixer".

    Note, when testing if you have sound, please copy and paste the following speaker-test into a Gnome terminal or a kde konsole:

    speaker-test -Dplug:front -c2 -l5 -twav

    Note Linux is case sensitive, and D is not the same as d. To stop the above test, while the konsole/xterm has the mouse focus, press <CTRL><C> on the keyboard. Note you should check your mixer settings (kmix if using KDE, and alsamixer if using Gnome) to ensure that PCM and Master Volume are set around 95%. Once you have basic sound established you can back off to lower volume levels. Note the test for surround sound is different.

    If that test yields errors (and its not uncommon to get errors there), try instead this more simple test:
    speaker-test -c2 -l5 -twav
    You should hear a female voice saying 'FRONT LEFT', 'FRONT RIGHT' five times. Its quite common that one of those speaker tests will work and one will NOT work, so don't be distressed if that is the case. IF that test gives sound, stop now, post that the sound test gives sound, and we will look at other possible causes for your applications not giving you the sound you want (such as missing codecs, using the wrong packaged version ... etc ... ).

    Or alternatively, for testing the simple playback, use aplay program. Prepare a WAV file and simply run like:
    Code:
    aplay -vv somefile.wav
    With the option -vv, aplay shows the verbose information of the PCM device, and a VU-peak meter during playing the file.

    Try those speaker-tests as both a regular user, and also with root permissions. If you have a headset, try with your headset plugged in, and also with your headset not plugged in (for speakers).

    Assuming no sound, can you provide more very detailed information so a good recommendation can be given? For openSUSE-11.1, you can do that, with your laptop connected to the internet, by opening a gnome-terminal or a kde konsole and twice copy and paste the following into that terminal/konsole
    Code:
    /usr/sbin/alsa-info.sh
    Run it the 1st time with root permissions. It will ask if you wish to do an update of the script. Select YES.

    Then run it again (as either a regular user or as root). This time it will diagnose your PC's hardware and software configuration for audio, and it will post its output on the Internet/web. It will give you the URL of the web site. Please post that URL here. JUST the URL.

    Also, please copy and paste the following commands one line at a time into a gnome-terminal or a konsole and post here the output:
    rpm -qa | grep alsa
    rpm -qa | grep pulse
    rpm -q libasound2
    uname -a
    cat /etc/modprobe.d/sound
    ... with that information I may be able to make a recommendation.

    Also, do NOT waste too much time on this. Simply post on our forum if you get stumped, and continue to look for help that way.

    We have a wireless sub-forum where our wireless experts hang out. That sub-forum is here: Wireless - openSUSE Forums

    Please go there, and make a new post with an appropriate title.

    Our wireless experts will NOT see this current thread with the title "unable to detect compaq presario laptop audio drivers" as needing their help, and hence it is very important you go to that wireless sub-forum and make an appropriate post asking for wireless help.

    BEFORE posting on that sub-forum, please read the 3 stickies on the top. Those stickies also advise what information you should provide in a post. If you do that, it will make getting your wireless working take place a lot quicker.
