Reply to Sound Card Manager / Audio Manager

Does any one know of any decent software for managing the sound in windows?

The built in windows audio control for playback devices is not a bad attempt at it but really want something where I can select multiple "sound devices" and test sounds with latency etc.

The reason for the question is I have a Vestax SPIN on Win 7, I plugged in, drivers self installed via Win Update and used the TSI map a very decent chap on here created (Oldfashioned I believe?). I also got told to install ASIO drivers, which I did and no matter which I select the sound is the exact same.

When I set Audio to Spin man the sound is awful, you can hear the beat pulsing static to the speakers without anything from the song coming through in an audible manner.

I believe the latency may be out, but I'm no sound engineer, so something of this standard would be fantastic.

I also bought a Numark IO soundcard... wondering if this is that much better than the built in spin controller that it would be beneficial to run it through it, or sell this unit on?

If I run via the onboard settings, sound is perfect but I'd really like to have this playing through external speakers!
