I have an Audigy 2 ZS which I upgraded to from onboard realtek sound
after having installed Half Life 2. I played the game with 2 speaker
settings and headphones and changed to 5.1 speakers but kept headphones
on through to the end and it was fine.

However recently Ive dumped the headphones and been using speakers and
today when I decided to play for a bit after not having used it since
headphones I find that the sound is static and crackling!

2 speaker sound and headphones = fine
5.1 sound and headphones = fine
2 speaker sound and speakers = fine
5.1 sound and speakers = crackling!

I don't get stuttering and also in Counter Strike source the sound is
fine on 5.1 with speakers!!!

Anyone had similar?

I found on the steam forums that doing
snd_mixahead -1 (negative 1) fixed the problem, though I think it made
in-game stuttering a little bit worse (I never really had a stuttering
problem).

I tried snd_mixahead -0.5 as well which I think was good too

start>run>dxdiag
then select either sound1 or sound2 tab whichever is the right one for your
audio card.

then play around with the acceleration, like try each differen setting
in-game and see if any other setting then the one its on now helps the
static.

also before doing this make sure the mixahead and mixprestep commands are
default, wrong values of these commands could cause this static.

dont have hl2 installed to tell you the exact cvar name but you should be
able to find it.
