Default no sound on fedora core 3

Hello Linux users,

I gave a try to Fedora Core 3 and I must say I finally found a distro
that fits my needs. I have configured everything to have a coherent and
functional desktop system I mean software, firefox plugins : i can even
view quicktime movies via mplayer-plugin, the only problem is that I
can only "view". not the slightest sound out there. My sound chip
(AC'97) seem to be detected and fully functional. I am running KDE,
could the problem come from ARTS sound server ?
There is no hardware problem with my sound card as it functions
correctly under windows and Knoppix.

Any suggestion ? thanks

PS: I got the same problem with Mandriva (formerly Mandrake) 10.1 (I
left it because of its inherent X server and font display problem and
its slowliness despite version and PC change)

I have the same sound chip. Here is the info from my audio devices probe:

Vendor: VIA
Model: Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller
Module: snd-via82xx


Probe for the sound card and then install the snd-via82xx series driver. It
took me a complete cold reboot for my system which I think must be
something in a hardware switch on board the AC97 chip.

Default Re: no sound on fedora core 3

Hi again Linux users,

I think I have identified the problem but still can't resolve it.

I have killed -SIGTERM ARTS server, then tried cat file.au >
/dev/audio, at that time I heard a little sound, I ran kmix and put the
master and PCM levels to the max, I repeated cat file.au > /dev/audio
and I could clearly hear the sound. Unfortunately :
1- Each time I quit Kmix or KDE the default parameters (low levels)
come back
2- I don't know what to do with ARTS

Does somebody has an idea about it ?

ciao

Usually kmix should save the settings on exit. Settings are stored
in ~/.kde/share/config/kmixctrlrc. Probably an access right
problem. In any case run alsamixer (assuming you're using ALSA)
from a terminal and set the card from here.Additionally make sure
KDE is configured for the sound system you are using (Control
Center->Sound & Multimedia->Sound System)

> 2- I don't know what to do with ARTS


Arts takes control over the sound device to allow simultaneous
sound events. When arts locks the device no other application can
use it.

To use arts with non-kde apps they either need to have build-in
arts support or you need to
- turn off arts before runnung them
- set arts to a low auto-suspend time (also in Sound System)
- use artsdsp

I guess your mplayer was not build with arts support.
