    Question Problems with audio and video


    Hello, I reccently installed Suse 11.1 in my laptop, but I have problems with the drivers of sound and video,

    laptop HP Compaq cq40 118AU

    Mi video card is ATI 3200 HD Series, and the max resolution is currently fixed in 24bits, in windows, I have until 32bits.

    There is no sound, I made a test and the alsa information is here:
    /tmp/alsa-info.txt.mqvd6goJw0

    Thanks, I'm new user in linux, and I will thank all the help you can give me.

    Its possible you have this set correctly, and you are running across different applications calling the same settings by different names, ... ie the 24-bit Linux is the same as the 32-bit Windows. ... I say "possible" as I am no expert in this. But I note: Color depth - Wikipedia, the free encyclopedia
    32-bit color
    "32-bit color" is generally a misnomer in regard to display color depth. While actual 32-bit color at ten to eleven bits per channel produces over 4.2 billion distinct colors, the term 32-bit color is most often a misuse referring to 24-bit color images with an additional eight bits of non-color data (I.E.: alpha, Z or bump data), or sometimes even to plain 24-bit data.

    Systems using more than 24 bits in a 32-bit pixel for actual color data exist, but most of them opt for a 30-bit implementation with two bits of padding so that they can have an even 10 bits of color for each channel, similar to many HiColor systems.
    ...

    Does that just obscure things, or does it possibly clarify ?

    OK, but I don't have access to your PC, and hence I do not have access to your PC's /tmp directory so I can not see that file.

    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

    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.

    I'm assuming openSUSE-11.1. If its not 11.1 tell me, and I'll change the above script command.

    Since you are new to Linux, here is a link to some basic openSUSE concepts:
    Concepts - openSUSE

    ... also, even though you have installed already, if you have not done so yet, you should now go through our installation stickie:
    NEWBIES - Suse-11.1 Pre-installation PLEASE READ - openSUSE Forums

    It has guidance that is useful after an installation, particulary wrt setting up your PCs software management repositories very conservatively (thats important for new users - ie only OSS, Non-OSS, Update and Packman repositories - leave no others permanently enabled)
