Horrible clicks and popping noise on pulseaudio/alsa playback on F10

Can anyone help me diagnose where to start with my awful symptoms of sound playback. Generally the sound plays well but for some annoying pops and clicks every 10 secs approx, like a scratched record!!

My (varied) setup is:

Server: Audio files on NAS1 -O/S - FreeNAS (v. 0.69b4 Sareer (revision 3864)) Server running firefly media server (v. svn-1586)

Client Software: Using RhythmBox (v. 0.11.6) for playback using ALSA (don't how to find out version number) and PulseAudio (Server v. 0.9.13, compiled with library version 0.9.8)

Client Hardware:
Creative Labs (v. 02:00.0 Multimedia audio controller: Creative Labs [SB Live! Value] EMU10k1X)
Client modules loaded:
lsmod|grep snd
snd_emu10k1x           18436  5 
snd_rawmidi            22528  1 snd_emu10k1x
snd_ac97_codec         95264  1 snd_emu10k1x
snd_seq_dummy           6660  0 
snd_seq_oss            30364  0

soundcore               9416  1 snd

snd_page_alloc         11016  2 snd_emu10k1x,snd_pcm
PA is obviously running. But I'm sure where to start - Client or Server - if it is server I will follow forums to firefly and Freenas. If Client - Hardware? or ALSA? or PA or Client Software?

Please let me know if you require anymore information

Think I'll jump in here just to get e-mails if / when this thread is updated. I have the same or similar issues with sound on my laptop. PulseAudio with Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller. Cracking / popping sounds during audio play back.

Edit This thread may be interesting. http://forums.fedoraforum.org/showthread.php?t=203708 Similar issues there?
