transfering my old headset onto my new pc issues

Hi everyone, i have been using these razer kraken pro since many years now and they provided me with absolute hearing power and they still do. My computer was getting old and it was time to change it. Installed my new rig on the desk follow by the usual updating/restarting required. Reinstalled razer synaspe for the surround pro. At this point surround was not activated, and the difference i could hear just from the swap between the two pc's was; sound volume was very low and on the systray it was set at 100% compared to the 50% on the old pc which was just loud enough without hurting my ears. Before trying a game i wanted to enable the 7.1 surround sound threw synaspe without success. I can hear the volume increase when i switch it on but there is (dont know how to call it) distortion, static? I tried many step-by-step from razer tutorial to whatever platform i could find since the last few days, without success. There is one thing that catched my eyes tho; - on the old pc windows default sound device is realtek digital output(realtek high definition audio) / inside razer synaspe it's the same and they never change no matter if surround is on or not. Well except maybe scenerio's where the portable speaker is on. - the new one, razer synaspe has speaker(realtek(R) audio) and window default output is the same without surround on. when turned on, synaspe stays the same and windows switches to speakers (razer surround audio controller). My first guest was it was working as intended but i do not explain the distortion. Let's check the mic, at least ill be able to talk back ingame. Nothing at all, but works fine on my old pc. If anyone could enlighten me i would greatly appreciate it
