HI,
I use a newly installed Fedora 8.Everything was working fine until I clicked on my volume control icon following which I wasn't able to hear any sound even after a reboot.

Here are somethings which would provide some info of my sound devices... etc.. etc

  [root@localhost ~]# cat /etc/modprobe.conf

From the evidence you have given me, there are 2 possible causes.

1. Check that your optical out isn't selected, you can find that on the switches tab of KMix

2. Sometimes your audio gets stuck in non-audio mode.

To verify 2:

on a konsole, as user, type in

Code:

iecset

Normal output:

Quote:

Mode: consumer
Data: audio
Rate: 48000 Hz
Copyright: permitted
Emphasis: none
Category: PCM coder
Original: original
Clock: 1000 ppm

If you see Data: non-audio

Try

Code:

iecset audio on

And see if that helps
