First, pulseaudio is not needed. It is not recommanded if you don't know what 
to do with it.

Did you check you turn on your audio system ? (quite often, it's basically set 
to mute).
Does your kernel recognize your audio system ?
Does kde recognize your audio system (there is a config panel about it) ?

Check that, and get back, you will help us to help you.
I am not the guy who will help you, I am not skilled in audio and alsa. But I 
know what others will ask for.

Additionally, have you added yourself to the audio group? The ALSA guide
is a good source for how to do these things:

What do the logs say? What gets printed on the console when you start
juk or vlc? Just seeing the message doesn't help. There are numerous
reasons for a device to not work.

The video plays but the first few seconds of audio is looping. The Flash
player in browser has also problems. The Youtube video plays only 3 seconds
and stops. Then if used the slider. then plays 3 seconds from new position
and stops. The video was fully buffered. still have this problem.

You have emerged alsa-firmware, but have not defined any device that may use 
said firmware?


BTW, please try not to top post - see my replies further down this thread.

Odd ... this is like a caching/buffering problem.

These are not related to your problem.  I get them here and there is no audio 
problem with my machine.

It may help to print your alsa-info output.  Someone who is better versed in 
audio matters may be able to see something amiss in there.

From a very quick scan I see:

!!Sound Servers on this system
!!----------------------------

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - No

I can't recall from your earlier posts.  Have you tried enabling pulseaudio?


Either way, I also see:

Simple mixer control 'CD',0
 Capabilities: pvolume pswitch penum
 Playback channels: Front Left - Front Right
 Limits: Playback 0 - 31
 Mono:
 Front Left: Playback 0 [0%] [-34.50dB] [off]
 Front Right: Playback 0 [0%] [-34.50dB] [off]

If juk reads this I am guessing that it will not make any sound.

You said in your second message that VLC works fine. Maybe your problem
is related to Xine (KDE applications use that usually)? What happens if
you switch the sound backend in KDE's configuration to VLC (that should
be the other there IIRC)? In either case, what do the logs
like /var/log/messages say?
