FC4 Video and Audio with Compaq Presario 2200 notebook


Hello,

I have installed Fedora Core 4 on my recently aquired Compaq Presario 2200. Install went ok. However, post install revealed that the sound card fails to initialize, and the resolution only goes up to 800x600. The machine came with Windows XP home already installed: the embeded wifi, audio and video al function properly there of course. So the problem is software, not hardware.

I have seen information on how to enable the wifi via ndiswrapper, I have not finished attempting install of the drivers just yet.

Please advise. I'd rather not use Windows full time.

Peace.

You should say what your lan, sound, and video cards are... output of lspci and dmesg should help here.

I've been able to fix the video.

You fixed the video - great! Please say what you did... after all, someone searching for just this issue will end up frustrated if you don't.

I take it you got as far as the sound test and heard nothing?

the first thing to try is running alsaconf as root.
then run alsamixer to make sure nothing is muted

--- failing that -----
AC97 is a supported codec, so it is the chipset driver you most probably lack.

Intel Corporation 82801DB/DBL/DBM
This is the same audio controlla as Dell Latitude D600 in the HCL. This works with the ALSA intel 8x0 module (SND-intel8x0) ... which is the same one I use and FC2 is supplied with it.

This leads me back to alsaconf.

I remember, I had an issue where sound vanished on me... and it turned out that the default stereo-out jack changed over. Swapping the speaker jack over solved the problem (and left a puzzle - I mean: how the... ?)

With most people it is just that everything is muted in alsa or something.

I found the fix for the vide via google. For what ever reason, FC4 didn't accurately detect the display. So i had to go to system-config-display (?) > Generic LCD > Generic 1024x768 (the actual text may not be accurate). I selected 1024 as I know that's the higest Windows up to on this laptop.

When I run system-config-soundcard, and try to play the test sound, the following erros show up, and the app stalls, with the button stil down:

"amixer: Unable to find simple control 'PCM-2',0

amixer: Unable to find simple control 'DRC Range',0"

I have no idea how to get more output. So it's not a matter of just not getting sound. It's a matter of the sound not gettign anywhere.

OK - apropos alsa will give you the range of alsa related tools.
In my box -
Code:
[~]$ apropos alsa
aconnect             (1)  - ALSA sequencer connection manager
ainit                (8)  - configuration tool for ALSA
alsactl              (1)  - advanced controls for ALSA soundcard driver
alsamixer            (1)  - soundcard mixer for ALSA soundcard driver, with ncurses interface
amidi                (1)  - read from and write to ALSA RawMIDI ports
amixer               (1)  - command-line mixer for ALSA soundcard driver
aplay                (1)  - command-line sound recorder and player for ALSA soundcard driver
arecord [aplay]      (1)  - command-line sound recorder and player for ALSA soundcard driver
aseqdump             (1)  - show the events received at an ALSA sequencer port
aseqnet              (1)  - ALSA sequencer connectors over network
speaker-test         (1)  - command-line speaker test tone generator for ALSA
Meanwhile, you have googled those errors right?

Run amixer directly from the command line.
You may need ainit, alsactl and alsamixer as well. It's probably something similar to the video card bug - FC4 and the card are not talking properly. Blame the card.

It's intreguing because I have neither of those controls and mine goes fine.
