Description of problem:
During the installation of FC5. my soundcard have been detected .
After i have configured tvtime,i got the image but instead of the normal sound
output on tv channels i had a horrible noise ( gresillements).
system-config-soundcard works intermettency.
I try to solve the problem by changing few parameters in /etc/modprobe.conf
like it is described in the alsa project documentation for my soundcard.
But it stills don't work.
Sorry for the english .
Version-Release number of selected component (if applicable):
i add the version of alsa.
when i try to run system-config-soundcard i had a failure on soundcard
detection. I' don't hear any sound.
When I run mplayer or xine i hear sounds but it's very low.
Steps to Reproduce:
1. # system-config-soundcard

Does mplayer/xine work for you? Have you checked the "alsamixer" utility for
setting up your card?
Yes mplayer and xine function correctly. I used the utility alsamixer however
the channels master and master-mono does not have any effect on the sound. Only
the channels pcm and via dxs modify the sound level. Via dxs seems to have
taken the place of the master control.
The channel line in works when i run tvtime and the horrible noise stopped when
i mute line in.
But as i said previously only for tvtime or xdtv i have horrible noise (
gresillement) instead of normal audio output from the current tv channel.
Please check the latest ALSA drivers (1.0.12.rc2), how-to is here:
