Strange sound probleem

[DaFixer]

Hi i have very strange audio probleem
I have try to get coax work on my onboard sound card, The realtek HD audio.
Analog (6 channel direct) works great. But when i use coax on my Logitech z55500. I hear that the sound stops for a half secLast Moonday) i get the Club3D Theatron Agrippa DTS with the post

And soax works great, But i have now a anhoter error/plroblem.
When i play a movie the backgrond music workts but the vol for speaking is very low
In wmp 11 works the sound normal

I think it is a codec probleem.
I have tryed in ACfilter but i can not fix it.

Can someone fix it?
