problem with ALSA and an audigy LS soundcaRD


hello

I am a new memeber of this forum, sorry if the question is simple.
I have a fedore 4 distribution. The sound card is a creative audigy LS one. I had some trouble during the installation of the distribution : the sound card was recognized (the hardware browser aisd so) but nothing was working....
I went to the ALSA website, read theHOIW\TO and begun to install trhe drivers, the lib and the util packages. After I ran these commands
./configure
make
make install
finally I used alsaconf to detect the card.

So, the card is recognized, I can play sound but the sound is completely weird, very noisy. Even if i used a command like this
sox source_file.wav -r 48000 target_file.wav
the sound is quite the same, even if the frequency rate is 48000 Hz (which seems top be the output rate after having seen speaker tests)

I do nor\t understand what happen and thank anybody who may help me

have u tried to use a .asoundrc file? I have an creative sound blaster live! 24 bit which is basicly the same as an audigy ls and if you say that alsa is working properly maybe u should try to use an .asoundrc file. Here is my .asoundrc file:

##################begin of .asoundrc file
pcm.sound-blaster{
type hw
card 0
}

pcm.sb {
type plug
slave.pcm "audigy"
}

pcm.audigy {
type dmix
ipc_key 1234
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
}

ctl.sound-blaster {
type hw
card 0
}

#the following lines create a multichanel sound device called default

pcm.!default {
type plug
slave.pcm "surround51"
slave.channels 6
route_policy duplicate
}
pcm.51mix {
type route
slave.pcm surround51
slave.channels 6
# Front-left
ttable.0.0 1
# Front-right
ttable.0.1 1
# Center
ttable.0.2 1.0
ttable.1.3 1.0
# Rear-right
ttable.0.4 1.0
ttable.1.4 1.0
# Rear-left
ttable.0.5 1.0
ttable.1.5 1.0
}

###########end of .asoundrc file

This configuration works for me but the bass is a bit too strong with the alsa drivers, in windows the bass is not so strong but I don't know how to fix this.... yet , anyway hope this works for u.
Good luck!!!
