Windows 7: Low volume on headset

My volume on my Steelseries 5H v2 is pretty low and im pretty sure it started after i got win 7 64bit. My volume should play twice as loud as it does right now, it also makes a little constant noise when no sound is played witch is annoying.

I tryed checking everything in the sound options and my Realtek HD Audio Manager witch is the software for my Asus P5Q Pro motherboard witch i use as soundcard. Every thing in windows and realtek is at 100% and other software as winamp. The volume scrool on my headset is at 100% too ofcourse.



My friend have exactly same headset and its twice as loud and i tested on my fathers Win XP and worked like a charm. Though im not sure its caused by windows 7, but i have a strong feeling.

Hope you can help me

EDIT: I have used the search button and didn't find anything that could help me.

What driver are you using? Is it working in device manager?

Device manager. You mean Playback Devices in windows sound options?
Realtek HD Audio Manager im using 6.0.1.5859 and audio codec is ALC1200.

I tryed updating the program and it worked Must have been a bug then.

...let me ask you something please..
don't know why but from not so long ago I don't hear dialog voices in my games.
It's something new because it was not my issue about month ago.
I have sound,I can hear everything but when two people speak to each other I can hear just a little bit,like they are far far away....
what seems to be my problem anyone can help?
best regards

EDIT
actually no problems any more...just reinstalled high def audio drivers and seems ok now
