sound card and driver on RH 7.1 laptop
in [Linux Hardware]
|
From: Allan Adler on 24 Feb 2007 22:05 I'd like to start working with sound on my Dell Latitude CsX laptop running RedHat 7.1 Linux. I'm pretty clueless. All I really know is that several years ago, when it was running RH 6, I had installed Csound and was producing some sounds with it, but I don't remember any details of how the sound was actually produced, except that I think I might have been using the resident xmms and some driver that was a demo, maybe oss, which expired after a month. When I upgraded to RH 7.1, I completely wiped the HD, so there are no traces of the earlier experiments with sound. On the theory that I did use oss, I downloaded an OSS3D demo and installed it. The install script says it succeded: Installation completed! Plugin installed to /home/allan/.xmms/Plugins/libxmoss3d.so and I checked that it is really there. Then I ran: [allan(a)localhost OSS]$ xmms /usr/share/sounds/gnibbles/laughter.wav and got a popup window telling me to check for the following: 1. I have the correct output plugin selected 2. No other program is blocking the soundcard 3. My soundcard is configured properly I don't know how to check these things. I also don't know how to find out what sound card I have. I executed dmesg and didn't see anything about sound cards. I also looked in /var/log/messages and found lots of occurrences of lines such as these: Feb 23 08:46:01 localhost modprobe: modprobe: Can't locate module sound-slot-0 Feb 23 08:46:01 localhost modprobe: modprobe: Can't locate module sound-service-0-0 I have no idea whether they are actually relevant, except for contaning the word sound. Apart from wanting to use xmms directly on sound files, I want to be able to use plaympeg to play mpg files that might have sound tracks. Presently, when I use plaympeg on mpg files such as: http://www-staff.it.uts.edu.au/~don/vogmovies/balmm.mpg it plays them but gives error messages such as: mcop warning: user defined signal handler found for SIG_PIPE, overriding Warning: Couldn't init SDL audio: No available audio device Will ignore audio stream This goes away if I run plaympeg with the --noaudio option. Now, admittedly, the mpg file in question doesn't have any audio, but I don't think that is the reason for the error message about audio. I think the reason has something to do with the absence of a driver for the sound card. In the hope of being able to make some sense out of the workings of plaympeg, I downloaded some stuff from http://www.libsdl.org and am trying to read the docs. Since they mention OpenGL, I should probably point out that I am not, as far as I am aware (which is not very far) using OpenGL. I use the Gnome desktop. Since someone will inevitably tell me to upgrade either my operating system or my hardware, I need to emphasize that neither is an option for me at this time. All I know is that sound used to work on this machine and I think it should still be possible to get it to work and probably all that is required is to find old versions of the right drivers. I just don't know exactly what to look for or where to look. -- Ignorantly, Allan Adler <ara(a)zurich.csail.mit.edu> * Disclaimer: I am a guest and *not* a member of the MIT CSAIL.

You might also try Googling "linux sound" and the name of your laptop. -- Q: Could you see him from where you were standing? A: I could see his head. Q: And where was his head?

I just tried it. The part of the output that looks relevant is: Multimedia audio controller: Neomagic Corporation NM2360 [MagicMedia 256ZX Audio] Now what do I do? -- Ignorantly, Allan Adler <ara(a)zurich.csail.mit.edu> * Disclaimer: I am a guest and *not* a member of the MIT CSAIL.

If it's less then that you could try a lightweight distro like Damn Small Linux. There has been a huge amount of progress in handling multimedia in the many years since Rh 7.1 came out. You could also see if you could install the mplayer RPMs, http://www.mplayerhq.hu/design7/dload.html
