Just for a base line try getting a list of running process.
Code:
ps aux| awk '{print $1, " ", $2, " ", $11}' >> Startup.log
Then run the code again but change the Log Output to another file. Check for any differences in the files. That will give you at least a start. Let me know if that does not help. If it does not we will have to come up with something else.

Thanks stephen for the help.
This is what I did.
Code:
[sumesh@saha ~]$ ps aux| awk '{print $1, " ", $2, " ", $11}' >> Startup.log
[sumesh@saha ~]$ ps aux| awk '{print $1, " ", $2, " ", $11}' >> Startup1.log
Both Startup.log and Startup1.log are exactly the same. In case if u want to have a look at the processes, I am pasting the output from one.

Code:

hmm.. try to check your syslog and see if any errors where logged regarding audio. Also does this just happen for a certain audio player? try restarting the pulseaudio.

I checked the following files...none of them made any sense...Are these the files, u suggested me to check?

Code:
[sumesh@saha ~]$ vi /usr/lib64/rsyslog/
[sumesh@saha ~]$ vi /sbin/rsyslogd 
[sumesh@saha ~]$ vi /etc/sysconfig/rsyslog
This happens with all my players...there is no sound at all !!!

I tried restarting the pulseaudio...this is what happened..
Code:
[sumesh@saha ~]$ pulseaudio restart
N: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration. However, we lack the necessary priviliges:
N: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant us priviliges. Dropping SUID again.
N: main.c: For enabling real-time scheduling please acquire the appropriate PolicyKit priviliges, or become a member of 'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user.
E: pid.c: Daemon already running.
W: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted
W: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted

E: socket-server.c: bind(): Address already in use
E: module.c: Failed to load  module "module-esound-protocol-unix" (argument: ""): initialization failed.
E: main.c: Module load failed.
E: main.c: Failed to initialize daemon.
E: pid.c: PID file '/tmp/pulse-sumesh/pid' not mine!

So, I changed to root..and,
Code:
[sumesh@saha ~]$ su
Password: 
[root@saha sumesh]# pulseaudio restart
W: main.c: This program is not intended to be run as root (unless --system is specified).
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL front:0
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL front:0
^C[root@saha sumesh]#
but had to press control+c to come out...
sorry for being dumb in replyin..but i am just tryin to learn linux.
And many thanx for helpin me. What shall I do now?
Thanks
Sumesh

I have my Sound Preference Devices set to ALSA and normally all is OK.

Default Mixer Tracks gives a choice of devices: HDA Intel (Alsa Mixer), USB Device Ox46d (which is my webcam), and Realtek ALC 861 (OSS mixer), which I believe is my on-board sound chip.
When HDA Intel (Alsa Mixer) is selected, all works OK.

My Volume Control gives the same choices, where the USB Device Ox46d is selected.

Sometimes on start up, Default Mixer Tracks sees only the USB Device Ox46d,
and the Volume Contol only sees HDA Intel (Alsa Mixer), and I get no sound at all.

Restarting sometimes cures the problem, and sometimes I have to shutdown and then restsart, but there seems to be no pattern to the occurences.

I am running Fedora 9, with Linux Kernel 2.6.27.5.41

Any suggestions will be appreciated.

I would venture out and say yes. So it sounds like a module issue where it is coming unloaded or something else is going on.
